Bi-metal reciprocating saw blades: a high-speed steel tooth edge welded to a flexible alloy backing, so the blade cuts metal without shattering when it catches an edge or bottoms out in a cut.
Why this blade
Bi-Metal, Not Carbon Steel: A bi-metal blade is a strip of high-speed steel teeth electron-beam welded to a flexible spring-steel back. That combination is what lets it cut steel and still bend instead of snapping when the shoe rides off the material. High-carbon blades are cheaper and cut wood faster, but they will not survive metal.
Why 24 TPI: Thin-wall material: EMT conduit, sheet metal under 1/8 in., copper and PVC pipe, aluminium trim. The finer pitch puts more teeth in the cut, which is what keeps thin stock from snagging and tearing.
Shank and Fit: Standard 1/2 in. universal shank, so the blade goes straight into Milwaukee Sawzall, DeWalt, Makita, Bosch, Ryobi and most other reciprocating saws and cordless sabre saws without an adapter.

Fit: standard 1/2 in. universal shank - fits Milwaukee Sawzall, DeWalt, Makita, Bosch, Ryobi and most reciprocating saws. No adapter needed.
Safety: wear eye and hearing protection, clamp the workpiece, and keep hands clear of the cut line. Reciprocating blades cut on both stroke directions - never reach under the material.
Shipping & returns: ships from our own stock. If a blade does not match the description, contact us and we will make it right.

Cutting Metal Without Wrecking the Blade
Run lower speed and light pressure, and let the blade do the work. High rpm on thin metal work-hardens the edge and strips teeth. Keep the shoe pressed against the workpiece so the blade does not chatter, and clear chips rather than pushing through a packed kerf.
Buy the Pack, Keep Cutting
Blades are consumables, and a crew burns through them. Against the 10-pack the 25-pack works out about 25% cheaper per blade and the 50-pack about 33%, so a spare rides on the truck instead of costing a supply-house run mid-job.
Repeat Supply for Crews and Facilities
Buying blades on a PO cycle rather than one pack at a time is how shops and maintenance departments actually control cost. Tell us the lengths and tooth counts you go through and we will quote standing quantities.
