Notes

• What is a "Depth Ring"?

Benefits

• Modified fish-tail point eliminates  backside breakout and splintering
• High flute volume supports high feed rates / chip loads
• Cutting edge geometry virtually eliminates chatter at high feed rates
• Flute geometry enhances rigidity for more accurate, single pass cutting at high chip loads

Applications

• Machining copper foil in zero-chemical 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
• Cutting and shaping mild steels
