FRACTIONAL & METRIC SERIES
• 4-margin design
improves accuracy and
surface finish along with
increased strength for
aggressive drilling
• Specialized selfcentering 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)
