Drill oversized holes in wood, metal and plastic without stepping up to a bigger drill. Every Irwin Silver & Deming bit is 6" long and carries a 1/2" reduced shank, so large cutting diameters still fit a standard 1/2" drill.

• 17/32" cutting diameter, 6" overall length
• 1/2" reduced shank fits all 1/2" drills
• Three-flatted shank design provides better chuck grip and reduces slippage - ideal for use in keyless chucks
• Constructed of M-7 high speed steel for high resistance to abrasion during tough drilling applications
• Standard 118 degree point for use in wood, metal and plastic
• Black oxide finish
• Size: 17/32"
