FRACTIONAL & METRIC
Hi-PerCarb
• Double margin design
improves accuracy and
surface finish along
with increased strength
for aggressive drilling
• Specialized self-
centering notched point
eliminates the need for
spot drilling decreasing
thrust and deflection
• Engineered edge
protection improves
edge strength and
reduces edge fatigue
allowing for increased
feed rates
• Recommended for
materials ≤ 56 HRc
(≤ 577 Bhn)
