Applications

• Machining counter-board channels in matrix and composite materials.
• Slotting FR-4 and other electronic substrates
• Engraving in thin substrates

Benefits

• Shallow fish tail point insures smooth channel profile 
• High flute volume supports high feed rates / chip loads
• Cutting edge geometry virtually eliminates chatter at high feed rates
• Straight flute geometry eliminates lifting and gouging of the substrate
