Best drill bit set

Updated: 2026-10-23

You searched for the best drill bit set and landed on boxes that all claim to drill everything, from £10.63 to £41.69. Those stars do not drill every material. The best drill bit set in this comparison is the listing that names your material and your diameter, and the skip is as useful as the pick. Prices and review counts are the amazon.co.uk lines in the [drill bit set comparison](/hub/drilling-and-accessories/drill-bit-set). Products Compared compared those eleven listings and did not run a lab test, on 21 October 2026. A qualifying purchase can earn a commission at no extra cost to you.

Best mixed set for shelves, plugs and screws

The Bosch 34-piece X-Line is £10.63 with 4.7 from 28,187 reviews, the deepest sample here. Masonry bits run from 5 mm to 8 mm, including 5.5 mm and 7 mm, and metal stops at 5 mm. It is the top pick when the plug is 5.5, 6 or 7 mm and the metal hole stays at 5 mm or under. The wood bullet prints 4/5/6/78 mm against a 4–8 mm contents line. Skip it for mild steel above 5 mm, a 10 mm plug, or stainless. The Bosch 50-piece X-Line is £14.49 with 4.7 from 16,733 reviews: HSS TiN metal from 1.5 mm to 6.5 mm, masonry from 4 mm to 10 mm, and spade bits at 16 mm and 22 mm. It is the best value once the plug pack asks for 7 mm or 10 mm. The weight field prints 18.1 g, and the material field says titanium while the bits are named HSS TiN. Skip it for 5.5 mm masonry, which this listing does not name. Do not fill the missing wood diameters from Expert Reviews or Screwfix. The 70-piece at £20.99 and the 91-piece V-Line at £31.52 are mostly screwdriver bits. Where a mixed case stops, including concrete, is the drill bit set for wood, metal and masonry. BLACK+DECKER’s A7188 at £15 names stone and does not list diameters. The 103-piece at £26.99 adds hole saws and skips 7 mm masonry.

Best set when the hole is in metal

The Bosch PointTeQ 19-piece is £14.12 with 4.5 from 5,060 reviews. Nineteen black-oxide HSS bits run from 1.0 mm to 10.0 mm in 0.5 mm steps, for alloyed and mild steel, non-ferrous metals, cast steel, cast iron and plastic. Masonry is absent, and the piece-count field says 1. It is the set for an 8 mm or 9.5 mm hole in mild steel. Reviewers praise the steps, and others say a bit snapped on first use. The Hurricane 230-piece at £41.69 repeats 1 mm, 1.5 mm and 2 mm and still stops at 10 mm. You are paying for spare small bits. No listing here is a clearly specified M35 or HSSE set. A titanium coat is still HSS.

Best set for thin sheet, and for softwood holes

Thin sheet is a step bit, not a twist bit that grabs as it breaks through. LSLANSOON at £12.99 does not list the steps, and a bullet says 118 degrees against 1183 in the spec. DelitonGude at £22.99 clashes HSS with a cobalt-steel field. Thickness is the HSS drill bit or step drill page. Softwood cable holes are the Bosch Expert six-piece spade set at £23.95: 13, 16, 19, 20, 22 and 25 mm, 1/4 inch hex, for softwood and particleboard, not hardwood, at 4.8 from 21 reviews. Skip it for oak. A faster-than-another-Bosch-part line is a claim on the page, not a test here.

Who should skip the top of the star list

The highest star line is 4.8 from 21 reviews, on the spade bits. The deepest sample is 4.7 from 28,187 reviews, on the 34-piece. Nothing here was lab-tested.

Common questions

What is the best drill bit set for home DIY?
For a shelf in brick and a few screws, the Bosch 34-piece X-Line at £10.63 is the top pick in this comparison, as long as masonry stays between 5 mm and 8 mm and metal stays at 5 mm or under. If the plug pack says 10 mm, the 50-piece at £14.49 is the better match. Best here means the listing that names your hole, not the highest star line.
Is the Bosch 50-piece X-Line enough?
It covers masonry from 4 mm to 10 mm and HSS metal from 1.5 mm to 6.5 mm, plus 16 mm and 22 mm spade bits, at £14.49. It does not include a named 5.5 mm masonry bit, mild steel above 6.5 mm, or stainless. The amazon.co.uk scope line cuts off the wood diameters, and the weight field of 18.1 g does not match a 50-piece case.
Which set is better for drilling steel?
The PointTeQ 19-piece at £14.12, from 1.0 mm to 10.0 mm in 0.5 mm steps. Mixed X-Line metal bits stop at 5 mm or 6.5 mm, so an 8 mm hole in mild steel is outside those cases. The Hurricane 230-piece reaches 10 mm as well, and most of the extra pieces are duplicate small sizes at £41.69. Skip both for a wall and for stainless.
Which set is for thin sheet metal?
The LSLANSOON step set at £12.99, with the limits on the page: steps not listed, 118 degrees against 1183 degrees, and dull-bit reviews beside one stainless-worktop comment. DelitonGude at £22.99 claims 44 sizes and conflicts on HSS versus cobalt, and the written reviews are not from the UK. A twist bit from PointTeQ is the better tool once the metal is thicker than thin sheet.
Which set should I skip for stainless steel?
All of them. No listing in this comparison is a clearly specified M35 or HSSE set. Titanium nitride on the Bosch metal bits, and the titanium coat on Hurricane and LSLANSOON, is still HSS. DelitonGude’s material field says cobalt steel while the title says high-speed steel, so that word is not settled. One LSLANSOON review mentions a stainless worktop, and that comment is not a reason to buy the set for stainless.
