Reduced Shank Drill Bit: 7/16", 135° Split Point, Black & Gold HSS, 3-Flats Shank

These high-speed steel jobber-length drill bits have a reduced shank that allows large diameter bits to be used in standard drill chucks. High Speed Steel drill bits absorb more shock and vibration than cobalt and carbide, making them suitable for use in manual drilling machines and handheld power tools. Jobber-Length drill bits are the most commonly used and provide a good balance of strength and accuracy when drilling into a variety of materials. Split Point drill bits are self-centering, requires less pressure to start, limits walking when used in stationary and portable drills. Spiral Flute drill bits are used in most general purpose holemaking applications to effectively evacuate chips as they drill into the workpiece.
