- Parabolic flute form and point combination produces closer hole tolerances, heightened chip breaking action, and improved coolant flow. Modified notch point increases stability and lessens work hardening. Wider flute spacing results in tighter, more manageable chips, and reduced chip packing. Titanium aluminum nitride (TiAlN) coating is resistant to oxidation and improves drill life, especially in conditions where high temperatures are generated.
