The Milwaukee 1/2" x 16" Flat Boring Bit gives you the extra reach you need without extensions. One bit does it all, saving time and eliminating the hassle. Double wing spurs reduce vibration, prevent breakout and facilitate easy 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 16" Flat Boring Bits in all universal QUIK-LOKTM extensions.
