The best rebar benders, compared.
Top pick: Zhildmosin bench bender, 4–14 mm – UK note that 14 mm steel was ample, stated at 4–14 mm, 5.0 from 4 ratings, at about £74.99. Not a lab test. Best value: MXBAOHENG bender, 1–14 mm – About £57.00, 5.0 from 4 ratings, and a UK review of 4 mm by 24 mm flat bar. Not a ribbed 14 mm trial. Updated 23 October 2026.
A rebar bender is a hand or bench tool that bends reinforcing bar, or a close cousin such as round bar and small flat. You buy one in the UK when a few hooks or a short return will not wait for a fabricator, and the bar is still small enough to bend cold on a fixed bench. Reinforcement normally arrives already cut and bent. Accurate bending needs a machine except on the smallest diameters. You tell a suitable tool by the printed diameter, whether the listing names ribbed bar or only smooth round, a former you can compare with the mandrel in BS 8666, and a base that stays put once it is fixed down. A listing that names no bent diameter is not that check. A structural schedule belongs with a fabricator. Diameter, mandrel and mounting are set out in the [rebar bender buying guide](/hub/diy-supplies/rebar-bender/sub/rebar-bender-buying-guide).

Personal buying guide
Question 1 of 2
What are you bending?
Zhildmosin's KQ-1908 is a bench pin stated at 4–14 mm, including deformed rods, at £74.99. The dimensions bullet gives a 22 by 15 cm base, a 30 cm solid handle, and a 40 cm hollow tube. Across 4 amazon.co.uk ratings the line is 5.0. A UK review from Wiltshire says the metal was more than ample for 14 mm steel. Two UK notes say it has to be mounted on a bench. Included parts are the mounting plate and the bender, not a listed bolt set. No former diameter is printed, so the 14 mm line is not a BS 8666 mandrel. It is the top pick in this set for someone who wants the one UK sentence about 14 mm steel, and it is the wrong tool if the bench will not take a fixed plate.
Pros
Cons
Best for: You want the UK note about 14 mm steel, and the bench will take a fixed plate.
Less suitable: A bench that will not take a fixed plate, or a job that needs a printed former diameter.
Specifications
Common questions
Does this listing say it bends 14 mm?
Yes. The bullets say 4–14 mm, including deformed rods, and a maximum of 14 mm iron bar. A UK review from Wiltshire says the metal was more than ample for 14 mm steel. No former diameter is printed.
Do I have to fix it down?
Included components name a mounting plate and the rod bender. Two UK reviews say it needs to be mounted on a bench. Bolts are not listed as a separate item.
How long is the handle?
The dimensions bullet says a 30 cm solid handle and a 40 cm extended hollow tube, and that measurements may vary slightly.
MXBAOHENG's ZWJ-14 is stated at 1–14 mm round steel and rebar, with threads included in the diameter, and a 180 degree claim, at £57.00. The handle bullet is 550 mm by 5 mm stainless steel. The item weight is 5.66 kg and the colour field is black. Across 4 amazon.co.uk ratings the line is 5.0. The detailed UK review bent 4 mm by 24 mm flat steel, filed weld crud off the turntable, and saw a slight twist when the set-up was not square. It does not describe ribbed 12 mm or 14 mm bar. Fixings are not in the included line, which says Machine. It is the best value here when flat bar and a long handle matter, and it is not evidence that 14 mm ribbed bar will follow the title.
Pros
Cons
Best for: Flat bar and a long handle matter more than a written trial of ribbed bar.
Less suitable: You need evidence that 14 mm ribbed bar will follow the title.
Specifications
Common questions
Is the 14 mm line backed by a UK review?
The bullet says 1–14 mm round steel and rebar, with threads included in the diameter. The detailed UK review bent 4 mm by 24 mm flat steel, not a named ribbed bar. Two of the four ratings have no written text.
What did the UK reviewer have to fix?
Welding crud on the turntable, filed off so the bar sat flat, and a slight twist if the tool is not set up squarely.
How long is the handle?
The bullet says a 550 mm by 5 mm stainless steel handle. Fixings are not in the included-components line, which says Machine.
CISSIYOG model 95193 is stated at 4–14 mm steel bars and small flat irons, at £60.99. The bullet gives a 220 by 150 mm base, a removable 300 mm handle, and 5 kg, which matches the item-weight field. Across 2 amazon.co.uk ratings the line is 5.0, and the listing has no review text, so nobody in this capture describes a diameter, a bench, or a fault. Fixings are not listed. The copper-pipe question is unanswered. Bullets also call the tool a sheet-metal bender and a pipe bender. Pins are described as quenched, with no diameter. It is a second CISSIYOG, not RebarBender01, and a silent 5.0 from 2 is not a reason to prefer it over a listing that has a written UK trial.
Pros
Cons
Best for: You are comparing a 4–14 mm listing with a printed 300 mm handle and a 220 by 150 mm base.
Less suitable: You want a written UK trial of a diameter, a bench, or a fault.
Specifications
Common questions
Is this the same tool as the other CISSIYOG?
No. This is model 95193, with a 220 by 150 mm base, a 300 mm handle, and a stated weight of 5 kg. The other CISSIYOG in this set is RebarBender01.
What bar does it claim?
4–14 mm steel bars and small flat irons. The copper-pipe question on the page is unanswered. No former diameter is printed.
What do the two ratings say?
The star line is 5.0 from 2. The listing has no review text, so there is no diameter, no bench note, and no fault to quote.
NiQiWuKin's Rb-58m is a hand bender stated up to 5/8 inch for flat steel and round rods, with a reverse head, at £76.91. The listing does not print millimetres, so it does not say 16 mm. The item weight is 2.7 kg and the package is about 89 cm long. Included parts are the bender and a user manual. Across 2 amazon.co.uk ratings the line is 5.0. The only text is a United States review: easier than a vice and pipe, dual pegs, welded, hollow handle that accepts a taper pipe. There is no UK review and no former diameter. It is the handheld in this set, not a bench plate, and a US sentence is not a UK trial of ribbed bar.
Pros
Cons
Best for: A handheld for flat and round steel stated up to 5/8 inch, not a bench plate.
Less suitable: You need a UK trial of ribbed bar, or a capacity printed in millimetres.
Specifications
Common questions
Is 5/8 inch the same as 16 mm on this listing?
The listing prints 5/8 inch and does not print millimetres. It does not say 16 mm. Flat steel and round rods are both named.
Is there a UK review?
No. The star line is 5.0 from 2. The only text is a United States review that praises the pegs and the welded build, and says a taper pipe can go inside the hollow handle.
What is the reverse head?
The bullet says a reverse head allows complex bends. No angle in degrees and no former diameter are printed. A user manual is in the included-components line.
KATSU Tools model 165193 is a bench-mounted metal bender for flat, round, square, and angle, at £164.99, with angles stated up to 120 degrees. The item weight is 29 kg. Forming parts are described as supplied, and the base has mounting holes. No rebar millimetre range is printed. This is not KATSU 165189 or 165190. Across 10 amazon.co.uk ratings the line is 4.4. UK reviews call it hefty and well engineered, medium duty, and, in one case, soft metal and cheaply made. A German review found the angle stop near 80 degrees. The hot-or-cold sentence is about supported sections, not an instruction to heat B500. Use it when the section is mixed, not when you need a printed 12 mm mandrel.
Pros
Cons
Best for: Mixed flat, round, square and angle, on a bench that can take 29 kg.
Less suitable: You need a printed 12 mm rebar mandrel.
Specifications
Common questions
Is this a 4–14 mm rebar pin?
No. Model 165193 is titled as a universal metal bender for flat, round, square, and angle, up to 120 degrees. It does not print a rebar diameter. It is not model 165189 or 165190.
What did UK reviews say?
One calls it hefty and well engineered, and had not tested the stated capacity. One calls it medium duty. One says it is made from soft metal and very cheaply made. The star line is 4.4 from 10, with four written reviews in the capture.
Will the stop reach 90 degrees?
The bullet says angles up to 120 degrees. A German review says the stop sat near 80 degrees, so that bend did not reach 90 degrees without a workaround. The machine weighs 29 kg.
CISSIYOG RebarBender01 is stated at 4–14 mm and 180 degrees, at £63.99, with 8.8-grade zinc-plated screws and a 7.5 mm U-block. The handle is 370 mm by 2.35 mm. The bullet says 6.4 kg and the item-weight field says 6.58 kg. The base is 195 by 180 mm with a 10 mm baffle. Across 5 amazon.co.uk ratings the line is 4.0. The only captured text is a German review that the tool broke on the third day, with no part and no bar size named. Four ratings have no text, and there is no UK review. The title also says pipe bender. Rank 21 in the browse node is not a quality score. Leave it if you need a UK sentence about 12 mm or 14 mm.
Pros
Cons
Best for: You are comparing the RebarBender01 listing, with a 180 degree claim and 8.8-grade screws.
Less suitable: You need a UK sentence about 12 mm or 14 mm bar.
Specifications
Common questions
What failed in the review?
The only captured review is from Germany. It says the item broke on the third day and that the buyer was disappointed. It does not name the part or the bar diameter. Four of the five ratings have no text.
Are the screws a full zinc coating?
The bullet says 8.8-grade zinc-plated screws, a 7.5 mm U-block, and quenched pins. It does not give a zinc mass for the body. The title also says pipe bender.
Which weight is printed?
The bullet says 6.4 kg. The item-weight field says 6.58 kg. The handle is printed as 370 mm by 2.35 mm.
Mekturm's WQJ-1 is the cheapest 4–14 mm listing in this set, at £42.88, with a 180 degree claim and six bearing units. The item weight is 4.98 kg. Across 3 amazon.co.uk ratings the line is 2.9, and all three reviews are written out. One UK review bent 12 mm after screwing the tool down and sliding a tube over the handle. One could not bend 12 mm on a scaffolding board and hired a hydraulic tool. One says you must bolt it down, that shims change the radius, and that the finish is plainer than the photos. Screws are described as included. No handle length and no former diameter are printed. Use it only on a solid bench, and do not read the browse rank as a test.
Pros
Cons
Best for: A solid bench, the included screws, and a lower shelf price, if you accept a 2.9 star line.
Less suitable: A scaffold board, or anyone reading the browse rank as a test.
Specifications
Common questions
Will it bend 12 mm rebar?
The bullet says 4–14 mm. One UK review bent 12 mm after screwing it down and sliding a tube over the handle. Another UK review could not bend 12 mm on a scaffolding board and hired a hydraulic tool.
Are fixing screws included?
The portable-design bullet says it can be installed on the workbench with the included screws. The page asks whether instructions are included and the listing does not answer.
Can I change the bend radius?
No former diameter is printed. One UK review used home-made shims and packing pieces to change the radius after practice, and said the finish was not as nice as the pictures.
DOODLREAM's listing is titled as two desktop benders at £17.89. The steel-rebar line is 1–4 mm, also written as 1/6 inch, with 10 mm aluminium or copper and a lever. Mounting is screws or a bench vice. The material line is carbon steel. The item weight is 1 kg. The included-components field says no, which fights the title's count of two. There is no star line and no review text. No former diameter and no handle length are printed. It is the cheapest tool kept, and it is not a 12 mm or 14 mm bender. Treat the 1–4 mm line as the limit.
Pros
Cons
Best for: Steel rebar stated at 1–4 mm, or 10 mm aluminium or copper, at the lowest price in this set.
Less suitable: 12 mm or 14 mm reinforcing bar.
Specifications
Common questions
Will this pair bend 12 mm rebar?
No figure on the listing says that. The steel-rebar line is 1–4 mm. Aluminium and copper are stated at 10 mm. There is no star line.
How many tools are in the box?
The title says 2 pieces. The included-components field says no. The item weight is 1 kg.
How does it fix down?
The bullet says screw fixation or a bench vice. It does not print a former diameter or a handle length.
Singring's mini is stated at 1–6 mm rebar, or 10 mm aluminium rod or copper core, at £29.59. The title also says 1/4 inch pipe and rebar bender. Two fixed columns are 12 mm in diameter with a 10.8 mm gap to the bearing, which is the tool size, not a 12 mm bar capacity. The handle is 340 mm and the weight is 920 g. Screws are provided for a bench. The body is called stainless steel and the columns quenched. There is no star line and no review text. A 180 degree claim is printed. It suits small rod, and it is the wrong row for 8 mm or 12 mm reinforcement.
Pros
Cons
Best for: Small rod stated at 1–6 mm rebar, or 10 mm aluminium or copper, on a bench.
Less suitable: 8 mm or 12 mm reinforcement.
Specifications
Common questions
Is 1–6 mm the rebar limit?
Yes, that is the rebar line. The same bullet allows 10 mm aluminium rod or copper core. The title also says 1/4 inch pipe. There is no review text.
What is the 12 mm column?
The size bullet says the two fixed columns are 12 mm in diameter, with a 10.8 mm gap to the bearing. That is the tool, not a bar capacity of 12 mm.
How do you mount it?
The how-to bullet says fix it to the workbench with the screws provided, then place the material between the two uprights. The handle is 340 mm. The weight is 920 g.
Shelf prices, stars and review notes are the amazon.co.uk figures already stored for these nine listings. This is not a lab test and not a BS 8666 check. The number on each card is the star line scaled to 100: 5.0 is 100, 4.4 is 88, 4.0 is 80, 2.9 is 58, and no star line is 0. A 5.0 from two ratings, with no written review, is not a strength test. The top pick and best value are separate from that number, because four listings score 100. The top pick is the bench pin with a UK note about 14 mm steel. Best value is the lower-priced bench pin whose UK review describes flat bar.
Star line
100%The card score is the amazon.co.uk star line times 20. A 5.0 is 100, a 4.4 is 88, a 4.0 is 80 and a 2.9 is 58. No star line scores 0. Stars are not a bend test, and a thin sample with no written review does not outrank a written UK note.
You are choosing a tool for reinforcing bar, round bar or small flat, not a fabricator. The nine amazon.co.uk listings in this set are not the same object: bench pins that print about 4–14 mm, two minis that state 1–4 mm or 1–6 mm, one 5/8 inch handheld, and a 29 kg workshop former. Shelf prices run from about £17.89 to about £164.99. None of them prints a former diameter you can set against BS 8666.
A rebar bender, for a UK shopper, is a hand or bench tool that bends reinforcing bar or a close cousin such as round bar and small flat. The Concrete Society says reinforcement normally arrives already cut and bent, and that accurate bending needs a machine except on the smallest diameters. On a small job you are choosing a tool, not replacing a fabricator. A structural schedule, a bar of 16 mm and above, or a bar you are trying to straighten out of concrete, belongs with a professional.
A bullet that says 4–14 mm does not say the bar is ribbed, and it does not print a former. Shopmp's GP-2, which is not in this set, already splits ribbed bar at 12 mm from smooth bar at 14 mm on a 25 mm radius core. Several of these bullets never make that split.
Singring states 1–6 mm rebar. Its 12 mm columns are the pins, not the bar. DOODLREAM states 1–4 mm steel rebar. Neither row becomes a 12 mm bender because the title says rebar.
UK notes say a bench pin has to be fixed down. One Mekturm review could not bend 12 mm on a scaffolding board and hired a hydraulic tool. A base that is not square can also twist the bar.
The first check is the bar you will bend, and whether it is ribbed B500 or smooth round. A trade tool outside this set limits a 25 mm radius core to ribbed bar at 12 mm and smooth bar at 14 mm. Several amazon.co.uk bullets never make that split. They print one range, often 4–14 mm. A mini that states 1–4 mm or 1–6 mm steel rebar is a different object. The 12 mm columns on the Singring listing are the pins, with a 10.8 mm gap, not a bar capacity of 12 mm.
BS 8666:2020 Table 2 sets the minimum mandrel at 24 mm for 6 mm bar, 32 mm for 8 mm, 40 mm for 10 mm, 48 mm for 12 mm and 64 mm for 16 mm, then 7d from 20 mm, which is 140 mm at 20 mm. The scheduling radius for 12 mm is 24 mm. Spring-back leaves a slightly larger radius. None of the nine listings prints a former diameter you can set against that table, so a 180 degree headline is not a 48 mm mandrel. Do not treat any listing here as BS 8666 compliant or CARES approved.
Three typical situations, each with a recommendation from this comparison.
You are fitting a few 8–12 mm hooks and the bench will take a fixed plate. Zhildmosin is the top pick at about £74.99, stated at 4–14 mm, with a UK review that calls 14 mm steel ample and 5.0 from 4 ratings. It is the wrong tool if the bench will not take a plate, and no former diameter is printed.
You are bending flat bar and want a long handle at a lower shelf price. MXBAOHENG is best value at about £57.00, stated at 1–14 mm, with a 550 mm handle and a UK review of 4 mm by 24 mm flat steel. That review is not ribbed 12 mm or 14 mm bar.
You also bend flat, square and angle, so a section former is closer than a 4–14 mm pin. KATSU 165193 is about £164.99, up to 120 degrees, at 29 kg, with 4.4 from 10 ratings. It prints no rebar diameter, and it is not KATSU 165189 or 165190.
The top pick is the Zhildmosin bench pin at about £74.99. The card score is 100, from 5.0 across 4 amazon.co.uk ratings, and a UK review says 14 mm steel was more than ample. It has to be mounted, and no former diameter is printed. That is not a lab test and not a BS 8666 claim. Best value is the MXBAOHENG bench pin at about £57.00, also a card score of 100, from 5.0 across 4 ratings. Its detailed UK review bent 4 mm by 24 mm flat steel, not ribbed 12 mm or 14 mm bar. The cheapest 4–14 mm pin, Mekturm at about £42.88, scores 58 from 2.9 across 3 ratings, so the lower price is not the award.
Zhildmosin bench bender, 4–14 mm
UK note that 14 mm steel was ample, stated at 4–14 mm, 5.0 from 4 ratings, at about £74.99. Not a lab test.
MXBAOHENG bender, 1–14 mm
About £57.00, 5.0 from 4 ratings, and a UK review of 4 mm by 24 mm flat bar. Not a ribbed 14 mm trial.
