The shortest flat boring bit on the market, the Milwaukee® 5/8" x 3-1/2" Stubby Flat Boring Bit lets you perform easy, clean wood boring in tight spaces. Whether you're working in a crawl space or drilling between studs, this bit provides the versatility and dependability you need. Double wing spurs reduce vibration, prevent breakout and optimize hole formation. A patented cutting edge makes wood boring easier and faster than with conventional flat bits. Chips won't cling, letting heat dissipate faster for maximum efficiency. For even greater versatility, the 1/4" quick-change hex shank allows you to use the Stubby Flat Boring Bits in all universal QUIK-LOKTM extensions.
