These FISCH Forstner bits have a periphery ‘Wave Cutter’ edge, 2 cutters and centre point allowing them to bore a very clean accurate hole.
The wavy cutting edge virtually eliminates the risk of tear-out, around the edge of the hole. The Wave edge generates considerably less heat and allows cutting speeds to be increased with less effort required to drill the hole.
Forged from one piece of high quality tool steel for extra strength the 1/4
