Plug and Tenon Cutters with Forstner Bits - Set of 4

This set contains four plug & tenon cutters and four perfectly matching forstner bits in 15mm, 20mm, 25mm and 30mm. Designed for use in a drill press, they will drill flawless holes and produce matching tenons and plugs in both hard and softwoods.

The plug and tenon cutters are manufactured from a special grade of high carbon steel which is extremely hard wearing and retains its hardness over prolonged use, resulting in a cutter that will not deform under heat and which will always keep the same cutting geometry, over its lifetime. The rim of the cutter finely scores the inner circumference of the hole, prior to five razor sharp cutting spurs removing the stock. This results in minimal fibre pull and tearing of the wood leaving extremely clean holes and plugs. They have an overall length of 140mm with a total available depth of cut of 80mm and 13mm round shanks

The forstner sawtooth bits are made from a special grade of high carbon steel which is extremely hard wearing and retains its hardness over prolonged use. The rim of the forstner bit is a fraction of a millimetre higher than the chippers which results in the bit entering the wood cleanly, prior to the chippers clearing the wood. The double-chip channels means swarf is quickly cleared, minimising rim heat, allowing for clean cut, flat bottom holes in hard, soft and exotic woods. The teeth have a skewed geometry to ensure minimal fibre pull and tearing of the wood. The bits are back tapered from the cutting edge to reduce friction and prevent binding and have been fully ground to give precise concentricity to ensure a highly accurate hole. The bits have an overall length of 90mm, with 10mm round shanks and are supplied in a wood box. ©
