TCFBA Carbide Auger Bit 25mm
Used for Crushgrind pepper Mills
This 400mm long Auger bit is ideal for drilling the bore down the middle of your grinders.
It drills a 25mm hole with two tungsten carbide cutters, making it especially appropriate for hard timbers.
I prefer the auger bits for this task because they clear the swath so much better than any other style of drill bit. However, I start the drilling of this hole with the more rigid Forstner bit that will accurately locate the centre and then change to the Auger bit once I have a hole approximately 50mm deep.
Lubricate your drill bits with linseed oil to put a halt to any of the squealing these drill bits can produce. (Brendan Stemp You Turn for more information )
