Cylinder Boring Bit, long version. Further details in the speed diagram

Bormax® 2.0 prima with exchangeable pre-drill bit, centre drill bit or guiding pin. Much less feed force needed as well as minimized friction and therefore less heat generation. Reasons: The two main cutting edges are grooved shifted, as well as the toothed linear grooved pre-cutters. A matching centre drill bit and an allen wrench are included in the delivery. Hexagonal shank for a better power transfer

The pilot-drill bit is ideal for drilling at an angle which is not 90° in workpieces surface, which occurs for example in the construction of staircase. Can be used with the centre point as traditional Bormax
