[QUOTE="Armeg UK, post: 456713, member: 18568"] Feel I should point out that the Acceler8% is actually a sheet steel holesaw. It's maximum capacity thickness material is set at 1.6mm. The reason behind this is that the clearance is only on the gaps between the teeth. Cutting tools need clearance to function, giving somewhere for the waste material (swarf, fines, debris, chippings etc.) to go. If you drill through material that is too thick you overload the gaps between the teeth and the waste material has nowhere to go. This will stop progress and the natural reaction at this point is to push harder. Heat then builds up which will acceler8 (see what I did there :D ) the wear. Mdf, plasterboard, plywood etc are all thicker than 1.6mm generally and therefore beyond the capabilities of the Acceler8% Many people do use them on plastic trunking etc. but we find that although it will not wear them out as quickly as steel, the discs of waste material sometimes fail to eject due to the expansive/contractive nature of plastic.
