Overview

- A great choice for non-ferrous metals

These PreciseBits brand stub end-mills feature a fish tail point that eliminates backside breakout and splintering. The high flute volume supports high feed rates / chip loads while the cutting edge geometry virtually eliminates chatter at high feed rates. Flute geometry enhances rigidity for more accurate, single pass cutting at high chip loads. These bits are a good choice for machining non-ferrous and precious metals for jewelry fabrication, engraving plaques, signs and awards, shaping high mineral content reconstituted stone products, and cutting and shaping mild steels.

Applications
  • Machining copper foil in mechanical printed circuit etching
  • Machining non-ferrous and precious metals for jewelry fabrication
  • Machining cold-rolled and mild steels (with cutting fluid)
  • Engraving plaques, signs and awards
  • Shaping high mineral content reconstituted stone products
