Made in Germany, these sets of high carbon steel Bormax forstner bits represent excellent value for money. The special wave form design of the bits reduces the surface area around the circumference of the bit which minimises friction and heat build up during cutting. Capable of cutting both hardwoods and softwoods, these forstner bits have a series of extremely sharp teeth which give an accurate, fast, clean cut and will also cut panel materials and plastic laminated boards without clogging. Precision machined to produce a true diameter, these bits perform extremely well when cutting overlapping holes or when drilling at an angle and create a flat bottomed hole. These forstner bits will retain a sharp edge and are fully resharpenable. In a recent test by an American woodworking magazine, these bits were voted best on test over seventeen other popular brands. These professional quality bits give outstanding performance. Presented in a wooden box, the set of five comprises 15, 20, 25, 30 and 35mm bits and the set of 15 comprises 10, 12, 15, 16, 18, 20, 22, 25, 26, 28, 30, 35, 40, 45 and 50mm bits.
