Contractors and DIYers, listen up! This Ideal Nailbiter ship auger is seriously tough stuff. That dual-helix cutter head means smoother, faster drilling through even the nastiest wood - we're talking nail-embedded timbers and all! The 60-degree angled design shears through wood cleanly without excessive chipping, while the oversized lead section pulls through thick timbers like butter. Made from fully hardened machine steel with black oxide coating, this thing resists warping and corrosion while delivering long-lasting performance. Measuring 7-1/2 inches total length with a 1-inch diameter and 5/8-inch cutting end, it's perfect for running wires through wood construction or any heavy-duty drilling job. The tapered dual flutes make chip removal easy without constantly pulling back, and the quick-change shank works with most drills. If you're tired of drill bits that can't handle tough jobs or break when they hit metal, this Nailbiter lives up to its name - it eats through nails and keeps on drilling!
