Bimetal Hole Saws are toothed HSS strips laser welded to a tough alloy body and disc. These precision manufactured Hole Saws that have outstanding strength, resilience and shatter resistance are manufactured in Bimetal M3 & 8% Cobalt grades.

Bimetal M3 Hole Saws are manufactured using the superior M3quality of High Speed Steel that is better than the conventional M2 grade. The M3 cutting edge has higher alloying elements that enhances the performance considerably and is useful for cutting aluminum, bakelite, brass, bronze, cast iron, mild steel, plastic, wood, etc.

Cobalt Hole Saws have 8% Cobalt in addition to normal alloying elements that can sustain higher temperatures, has more hardness and greater wear resistance. They are therefore recommended for cutting difficult materials like cast steels, duralium, hardwood, inconel, inox, non-ferrous alloys, plaster of paris, stainless steel, etc.
