BI-Metal M42

Simmons’ Bi-Metal blades have especially hard tooth tips made of M42 high speed steel and an alloy backing with 4% chromium to allow the blades to withstand the severe stresses exerted by modern high production band saw machines. They are excellent for cutting all metals with a hardness maximum of 50 on the Rockwell C scale. They last approximately ten times longer than regular carbon steel band saw blades, which leaves you with far less down time for changing blades and a reduced cost per cut. Bi-Metal blades are advantageous to use for materials that are difficult to cut due to their hardness or their abrasiveness.
