Hole Saws
Bimetal Hole Saws (article 75) have got a crown made of HSS M3 steel with variable pitch toothing coupled with a body of special steel. This technology makes them very heat resistant and abrasion-proof during their high speed rotation. For this reason they are suitable to drill in thin metal sheets, plastic, synthetic resin, wood and multilayer.
Height: 45 mm. Useful height: 40 mm.
