Benchmark Abrasives 12" x 24 TPI bi-metal hacksaw blades combine a flexible heat-treated steel body with an 8% cobalt high-speed steel cutting edge for durable, controlled manual cutting. The finer 24 TPI tooth pitch increases tooth engagement for smoother cuts, making these blades a strong choice for smaller metal sections, pipe, angles, and other applications where a coarser blade may be too aggressive.
Designed for standard 12" manual hacksaw frames, these blades are well suited for fabrication, maintenance, plumbing, repair, and general shop work. The 24 TPI configuration provides a useful balance of cutting control and finish while still offering enough chip clearance for many everyday cutting applications.

Applications
24 TPI is a finer tooth pitch suited to smaller sections and applications where increased tooth engagement and a smoother cut are preferred.
Common applications include:
Metal pipe
Tubing
Angle iron
Smaller metal sections
Ferrous metals
Plastic
PVC
ABS
Occasional small wood cuts
Small nail-embedded wood sections
Fabrication and repair work
Plumbing and maintenance cutting
For best performance, select a tooth pitch that keeps at least three teeth engaged in the material throughout the cut.
Hacksaw Frame Compatibility
Designed for 12" manual hacksaw frames.
Compatible examples include:
Benchmark Abrasives Deluxe High Tension Hacksaw
Milwaukee® 48-22-0050
LENOX® 12132HT50
Bahco® 325
Verify that the blade seats securely on both mounting pins and that the frame can properly align and tension the blade before cutting.
Safety Tips
Wear safety glasses and any additional PPE appropriate for the material being cut.
Secure the workpiece firmly before beginning the cut.
Verify that the blade is properly installed, aligned, and tensioned.
Install the blade with the teeth oriented in the cutting direction specified by the saw frame.
Maintain adequate tooth engagement throughout the cut.
Avoid excessive pressure when starting a cut on an edge or corner.
Reduce pressure on the return stroke to help protect the blade teeth.
Replace blades that are damaged, cracked, bent, excessively worn, or missing teeth.

Frequently Asked Questions
TPI means teeth per inch. A 24 TPI blade has a finer tooth pitch than 14 or 18 TPI blades, placing more teeth in contact with the material during the cut.
24 TPI is well suited for smaller sections, pipe, angles, and other workpieces where increased tooth engagement and a smoother cut are preferred.
They are suitable for common manual cutting applications involving ferrous metals, plastic, PVC, ABS, small wood sections, and small nail-embedded wood sections when the workpiece thickness is appropriate for the 24 TPI tooth pitch.
Yes. These bi-metal hacksaw blades are designed for manual metal-cutting applications including pipe, tubing, angle iron, smaller metal sections, and other common ferrous materials.
24 TPI places more teeth in the cut, which generally provides smoother cutting and better tooth engagement on smaller or thinner sections. An 18 TPI blade provides more chip clearance and is a stronger general-purpose choice for somewhat larger sections.
32 TPI is the finer option when cutting light tubing, sheet, and other thin materials where maintaining adequate tooth engagement is especially important.
A useful general guideline is to maintain at least three teeth in the cut throughout the cut. This helps distribute cutting pressure and reduces the chance of individual teeth snagging or stripping.
Yes. The Benchmark Abrasives Deluxe High Tension Hacksaw is designed for 12" manual hacksaw blades.
These blades are designed for the standard 12" manual hacksaw format. Other frames to check for fit include Milwaukee 48-22-0050, LENOX 12132HT50, and Bahco 325. Confirm that both mounting holes seat securely and the frame tensions the blade correctly.
No. These are manual hacksaw blades for 12" hand hacksaw frames. They are not intended for powered reciprocating saws, pneumatic air saws, or industrial power hacksaws.
