Features of Dimple Bar

Highly rigid steel shank and a lightweight head configuration designed by computer simulation analysis reduces chatter and improves the vibration damping properties.

FEATURES OF DIMPLE BAR

Deflection Resistance

DEFLECTION RESISTANCE

The unique cross sectional shape engineered into the dimple effectively balances the cutting forces (principal and back force), and reduces deflection by up to 17 %.
