Milwaukee Stubby Flat Boring Bit, 1/2 In. X 6 In. The stubby flat boring bits are ideal for tradesmen and women who demand a wood boring solution in tight spaces. Whether in crawl spaces or just drilling in between studs, the stubby flat boring bits provide versatility and dependability. The double wing spurs reduce vibration, prevent "break out" and produce easy hole formation. The patented cutting edge produces easier and faster wood boring over conventional models by having fast chip removal, which dissipates heat from the bit. The 1/4 in. quick-change hex shank allows use in all universal QUIK-LOK extensions. This product is manufactured in China.
