PreciseBits MM308 Deep Reach End Mill

Overview

The MM308 series of end mills from PreciseBits are a 3-flute deep reach carbide tool designed for materials such as woods and sign board.

The 'fishtail' tip helps to eliminate backside breakage and splintering while the high flute volume supports high feed rates / chip loads. The 3-Flute design reduces resonance and chatter under high chip loads, and the DeepReach design optimized for high-relief carving.
