About This
- SUIT YOUR NEEDS: 3-step sizes include 1/4", 7/8" and 1-1/8". The 135 ° cutting angle reduces self-wear and provides a larger stress area, resulting in cleaner, more efficient drilling for home repairs and metalworking.
- IMPROVED Stability: Four cutting blades are designed for increased stability, effectively reducing deviation during the cutting process. It offers a significantly longer service life compared to regular step drills.
- M35 Cobalt Material: M35 cobalt high-speed steel, through heat treatment, achieves toughness and bending strength that surpasses standard high-speed steel, making this step drill bit more suitable for cutting hard materials.
