The Spyder Stinger™ auger bit features an innovative non-clogging, automatic-feeding precision tip for optimal speed, accuracy and no thrust drilling. Hardened cutting edges on this two-fluted bit run smoother than single-flute bits providing greater control and less vibration which makes them ideal for deep hole boring in nail embedded wood. Chuck them into your impacting tool for even greater drilling power. Up to 20x faster and 10x more holes per charge than conventional spade bits Stinger™ threaded tip automatically engages the work surface without clogging or wandering for faster no-thrust drilling 7/16-in impact-rated speed hex won't slip in the chuck and is ideal for use in quick-change battery-powered impact drivers Black oxide finish for increased durability and lubricity Hardened cutting edges power through nail-embedded wood with greater control and less vibration Two-flute design provides optimal chip flow and reduced cutting friction Ideal for use on soft and hard woods, wood with nails, plastic/PVC, plywood, laminated wood, MDF and particle board 6-1/2-In overall length Sub-Brand: Stinger Bit Diameter (Inches): 1-3/8-in Bit Length: 6-1/2-in Shank Size: 7/16-in Bit Type: Auger bit Case Type: N/A (no case) For Use on Metal: No For Use on Wood: Yes For Use With: Power tool Material: High-speed steel Package Quantity: 1 Quick Change: Yes Set/Individual: Individual Shank Type: Hex Warranty: None Brand/Model Compatibility: Universal CA Residents: Prop 65 Warning(s): Yes UNSPSC: 27112800
