14-Piece Titanium-Coated Impact Drill Bit Set with 1/4-Inch Hex Shanks and 135° Split Points, 1/16–1/2 Inch
14-Piece Titanium-Coated Impact Drill Bit Set with 1/4-Inch Hex Shanks and 135° Split Points, 1/16–1/2 Inch
A titanium-coated impact drill bit set makes clean holes in ferrous and non-ferrous metal, cast iron, stainless steel, wood and plastic with quick-change convenience. The 135-degree split points start faster and resist walking, while titanium nitride coating is listed to last 2.5 times longer than comparable uncoated bits.
All 14 pieces use 1/4-inch hex shanks for compatible impact drivers, allowing fast changes without a keyed chuck. Sizes span 1/16 through 1/2 inch and include a duplicate 1/8-inch bit for a frequently used diameter. The compact case keeps each bit visible and ready for repair, fabrication or general construction work.
