3041003 Speedbor Max 3-pc. Drill Bit Set, Tri-flute, Hex Shank

The Irwin Speedbor Max 3-Piece Drill Bit Set is a spade bit set with tri-flute design for faster chip ejection and a full screw tip that allows the bit to self-feed. The grooved hex shank prevents slipping in a drill chuck and fits standard 1/4-inch quick-change chucks, making it suitable for drilling tasks where consistent, accurate results are needed.

This set is built from durable carbon steel, making it ideal for repetitive drilling applications. The tri-flute design helps maintain drilling speed by clearing chips fast. The three-edge cutting spurs add durability to the bit, while the full screw tip drives the bit forward for smoother operation.
