Bi-Metal Hole Saw 195mm (7-2/3") M42 HSS (High Speed Steel) Hole Saw Drill Bit Cutter for Wood Plastic Metal Sheet Plasterboard ABS Enclosures Linear bearings are linear motionThe bi metal hole saw combines high speed steel and cobalt. The hole saw body is made of superior grade M42 high speed steel, which has excellent hardness, wear resistance, and heat resistance. The cutting edges or teeth are made of a cobalt alloy, which further enhances hardness and heat resistance. The sprayed coating resists rust and corrosion. Sharp toothed edges allow for smooth, fast and easy cuts. Bi metal hole saws have larger numbers of
