Center Drill: Plain Type, #3/0, 90°, 1 1/4 in Overall Lg, High Speed Steel

Center drills with a plain tip are the standard choice for creating center holes in a piece of stock to prepare it for turning between centers on a lathe. High Speed Steel center drills offer good wear resistance, have some flexibility, and can absorb some shock and vibration. Bright (Uncoated) coating can be resharpened and is a good choice for use on soft materials, such as aluminum and low-carbon steel. 90 ° countersink angle is for standard (imperial) flat- and oval-head screws, as well as enlarging existing holes.
