Irwin 63905 Titanium Nitride Coated High-Speed Steel 135° Split-Point Drill Bit
The Irwin 63905 Titanium Nitride Coated High-Speed Steel 135° Split-Point Drill Bit is engineered for demanding metal-drilling applications on the job site or in the shop, and this family is available in sizes ranging from 5/64" to 11/32" to match a wide range of hole-diameter requirements. Every size shares the same core specification: a Titanium Nitride coating, premium high-speed steel construction, a 135-Degree split-point tip, and a straight shank sized for standard drill chucks. The Titanium Nitride coating resists heat and friction, extending cutting edge life up to 6 times that of other high-speed step drill bits, while the split-point tip starts drilling immediately with less force and eliminates walking across the work surface for accurate hole placement.

Why Irwin?
Irwin builds every size in this 63905 family from premium high-speed steel and applies a Titanium Nitride coating specifically to fight the heat and friction that shorten the life of standard bits, delivering cutting edge life up to 6 times longer than other high-speed step drill bits. The 135-Degree split-point tip is designed to bite in immediately and track true across the full 5/64" to 11/32" size range, reducing operator effort and preventing the tip from walking off-mark on the work surface. For professionals and serious DIYers who need metal-drilling bits that hold up to repeated use, the Irwin 63905 family combines durable materials with a purpose-built tip geometry and a straight shank for dependable, accurate performance in any size.
