Irwin claims their new Blue-Groove point and cutting edge promotes faster chip removal: 4x faster than standard spade bits. Other features include:
- double cutting spurs to scribe the outside of the hole, reducing breakout
- a 10% larger shank for added durability
- grooved hex shank to prevent slipping in drill chuck or bit extension
Irwin says it’ll fit all standard quick change chucks, and they come in short, standard, and extra-long lengths.
