IDEAL Nailbiter™ 18 in. Ship Auger provides a smooth and reliable drilling application. The efficient driver-drill works its way through treated, wet and even nail embedded wood without jamming. The auger features an oversized head and dual cutting edges for easy, durable and efficient drilling. The unique 60 deg. angled design of the drill bit cuts through wood cleanly without generating excessive chips. Constructed using hardened machine steel with a black oxide coating the auger is long-lasting and resists corrosion. The bit's cutting edge can be re-sharpened easily when required.
