73320 Turbo Max Jobber Drill Bit, 5/16-In., High Speed Steel
Description
The Irwin 73320 Turbo Max Jobber Drill Bit is a 5/16-inch high-speed steel drill bit featuring a Turbo Max tip that eliminates walking on flat and curved surfaces, ensuring exact centering and burr-free holes. This jobber-length bit is built for reliable drilling performance with precision construction.
The 135° Turbo Max point geometry automatically centers the bit on the work surface, preventing deflection and walking. The precision-ground spiral flutes and black and gold oxide coating work together to reduce wear, keep the bit sharp longer, and resist corrosion during storage and use. The three-flattened shank provides superior grip in the chuck for stable operation.
