How to choose a masonry reciprocating saw blade

Updated: 22 October 2026

You are about to buy one masonry reciprocating saw blade, and the listing in front of you says concrete in the title. That word is not a decision. The useful order is the material, the printed exclusion, the working length, the tooth pitch, then the pack and the saw. A bi-metal blade at 8 to 14 teeth per inch belongs in a different category, and a short blade will not cross a thick cavity wall. This page is that decision order, not a ranking. The grid is the [reciprocating saw blade masonry comparison](/hub/saw-accessories/reciprocating-saw-blade-masonry). Peter F. checked the listings on 20 October 2026. This is not a lab cut.

Match the edge to the material

A carbide tooth is the edge for aerated block, hollow brick, fibre cement and ordinary brick. Carbide grit is a different tool. The PAYA PYRCB9G is a 228 mm, 40–50 grit three-piece pack at £21.50, named for tile, plasterboard, fibreboard, lightweight brick and sintered stone. No UK review text is stored, so it is a listing match, not a proven brick cutter. An 8–14 TPI bi-metal blade will skate or burn on masonry. Facing brick wants teeth. Tile or a brittle sheet wants grit.

Read the exclusion, not the word concrete

The TOLESA 300 mm 2 TPI blade at £17.99, the EXFEIN 305 mm 2 TPI two-pack at £23.99, and the EZARC 450 mm blade at £23.37 say they are not for stones, hard rocks, cement blocks or fine branches. The MUOZLOP 380 mm three-pack at £35.14 says it cannot cut concrete that contains stones. A title that still says concrete does not override that sentence. Under the Consumer Rights Act 2015, goods must match their description, so believe the exclusion when the title and the bullets disagree. A dense cement block in a garage wall is the worked example: the title looks helpful and the bullet rules the blade out. A dust-reduced or 50 percent faster line is not a measurement.

Length is the cut plus the shank

The shank stays outside the cut. Bosch’s S 1141 HM is 225 mm overall for a stated 175 mm cut. That gap is the holder. In this set, EXFEIN states 305 mm total and 253 mm working. EZARC’s 450 mm “entire block” line is a listing claim, not a measured depth. A blade of about 228 mm, such as the Saxton at £10.99, or a 10 inch Fyeme at £6.99, will not cross a thick cavity wall.

Pitch, the saw, and the pack

On brick, Hilti’s brick blades and Eclipse’s brick blade are both 2 TPI. On aerated concrete, Bosch and Hilti publish 3 TPI, still a coarse tooth. Where a listing leaves teeth per inch blank, do not invent a figure. Fyeme, both CECOMBINE packs and the EZARC 450 mm blade do not state a pitch. PAYA is grit, so teeth per inch does not apply. A 380 mm or 450 mm blade needs a saw that can hold a straight stroke. A small cordless saw often cannot keep a long blade from whipping. The CECOMBINE value pack at £19.99 shows 5.0 from one rating, says five pieces in the set name, and also says two items. Check the live count.

When not to buy from this set

Do not buy these blades for dense concrete, engineering brick, stone or reinforced concrete. A load-bearing opening is a builder’s job. If the wall is ordinary brick or cement board and the length clears it, the best reciprocating saw blade for brick page names one top pick and one best value. If the piece is aircrete, length against thickness is on the reciprocating saw blade for aerated concrete page. A dust-reduced slot is not the silica limit of 0.1 mg/m³ over eight hours.

Common questions

Do I need carbide teeth or carbide grit for brick?
For ordinary brick, aerated block, hollow brick and fibre cement, buy carbide teeth. Carbide grit, such as the 40–50 grit PAYA at 228 mm, matches tile, plasterboard and brittle sheet on its listing. No UK review text is stored for that grit pack, so do not treat it as a tested brick blade. A bi-metal blade at a fine pitch is the wrong category for either job.
Is 2 TPI or 3 TPI the masonry pitch?
Brick blades from Hilti UK and from Eclipse are 2 TPI. Bosch’s aerated S 1141 HM is 3 TPI, with 8.5 mm spacing, and Hilti’s aerated blades are also 3 TPI. Both are coarse. A higher pitch is for metal. If the listing does not print a pitch, the figure is not stated. Do not copy 2 TPI from a different EZARC page onto the 450 mm listing in this set.
What does “not for cement blocks” mean if the title says concrete?
Believe the exclusion. TOLESA, EXFEIN and EZARC say they are not for stones, hard rocks, cement blocks or fine branches. MUOZLOP says it cannot cut concrete that contains stones. When the title and the bullets disagree, the Consumer Rights Act 2015 expects the goods to match the description you relied on, and the safer reading is the stop list.
Is one blade enough if the pack count disagrees with the title?
One blade can finish a short job, and a second is rational because teeth snap when you force the cut. The CECOMBINE value pack says five pieces in the set name and two in the number-of-items field, with 5.0 from a single rating and no review text. Confirm the count on the live amazon.co.uk page before you pay £19.99 for a five-pack.
Does a dust-reduced bullet mean the cut meets the silica limit?
No. The Health and Safety Executive workplace exposure limit for respirable crystalline silica is 0.1 mg/m³ over eight hours. A slotted blade or a dust-reduced bullet is not that measurement, and it is not extraction. If the cut can be avoided, avoid it. The exposure rules are written for work, and they still describe the dust you would rather not breathe at home.
