FAMAG Series 1493 hardwood auger bit This hardwood auger bit from FAMAG is suited not only for European hardwoods but also for much harder tropical hardwoods such as bongossi. Without the pre-cutter usual for most hardwood augers, but with a special bottom blade. This keeps the heat build-up to a low level. Tool steel for a long service life. With hexagonal shaft for secure retention in a drilling machine.
Recommended rpm: 700 to 2250, depending on size, the bigger the size, the lower the speed. The recommended speed for a 12 mm drill bit, for example, is 1500 rpm.
