Frequently through-holes have to be made in wood, medium density fibreboard or also plaster boards. For this are hole saws ideal. But traditional bimetal hole saws are improper for this application area. Due to relative small sprockets and chip spaces, the hole saws are rapidly getting plugged up with chips. This only causes unwished heat and finally leads to a "burning" but assures no further progress of drilling.

Ideal for applications in all sorts of wood are the carbide tipped hole saws "Multi Purpose". Depending on the diameter these hole saws have different numbers of carbide sprockets. The big chip spaces around the carbide sprocket, in which the chips can be collected ideally, are always the same. So there doesn't accrue a plug of the hole saw with the well known aggravating consequences.

But these hole saws can do even more. Beside all sorts of wood (such as soft wood, hard wood, medium density fibreboard, chip trays and compressed wood) the Multi Purpose hole saws can also cut lots of plastics like nylon, Trespa and PVC.

Extremely professional you work with these hole saws also in materials like hard plaster, cellular concrete, gas concrete and flagging with a scratch hardness of max. 6. With these application areas the hole saws become an all-purpose tool and are indispensable for professional craftsmen and professional "Do-it-yourself" workmen.
