Bimetal hole saws





Teeth are alternate and side set. Ideal for mild steel stainless steel, non-ferrous metals, aluminium, cast iron, copper, zinc.
TECHNICAL FEATURES :
- Perfect round back plate.
- Fast & easy center drill change.
- Thick steel body.
Bimetal Plus 8% CobaltPremium bi-metal with 8% cobalt provides Xtreme results in performance and up to 50% longer lifetime than the competition.
Tooth designSpecial tooth geometry with regular pitch provides a smoother cut and better chip clearance preventing clogging and heat build-up. Teeth are alternate & side set to minimize binding and friction, requiring less feed pressure.
Materials :
- Metals (up to 1000 N/mm2 strenght).
- Mild steel.
- Stainless steel.
- Non-ferrous metals, aluminium.
- Sandwich materials.
- Cast Iron.
- Copper, zinc, brass.
Speed kills! Operating at higher speeds than those recommended will shorten hole saw life and produce very inefficient cutting.
