This IRWIN 3018003 drill bit is part of a twenty-nine piece titanium-nitride-coated set. It features a design that reduces friction and withstands heat, extending the life of the cutting edge. These drill bits are suitable for repetitive metal drilling with both portable drills and stationary drill presses.
Titanium-coated nitride drill bits are durable and maintain a sharp cutting edge.
The 135-degree split-point tip starts drilling immediately and helps prevent walking.
Reduced shank above three-eighths of an inch allows larger drill bits to fit in a three-eighths chuck.
