Precise Bits MM208 Extended Length

Overview

The MM208 series of end mills from PreciseBits are a 2-flute extended length carbide tool designed for materials such as woods and plastics. They are good choices for applications such as dimensional signage and 3D contouring.

The 'fishtail' tip helps to eliminate backside breakage and splintering while the high flute volume supports high feed rates / chip loads. The cutting geometry enhances rigidity for more accurate, single pass cutting at high chip loads. Compatible with ebony, rosewood and all other hardwoods
