Jobber Drill Bit, #27, High Speed Steel, TiN

This notched-point drill bit is designed to withstand higher thrust loads with heavy web drills. It also features a parabolic flute form for tight hole tolerances, increased chip-breaking action, and improved coolant flow. Its wide flute spacing offers tighter, more manageable chips and reduced chip packing. The TiN (titanium nitride) coating helps to lengthen tool life and allow higher speeds with added lubricity. For ferrous metals, tough alloys, and nonmetallic materials.
