- Type QUAD EDGE™: unique combination of a 135° split point and four cutting edges: the 135° split point allows for precise and fast drilling without walking.
- Four cutting edges create smaller chips to prevent heat buildup for longer lifespan.
- Variable flute geometry: for faster material ejection. Helps the piece to operate cooler and not burn out quickly.
- Reinforced tapered web: wider core towards the drill's shank. Enhances the core to increase the overall flute strength.
- 3 flat sides on the shank for drills above ⌀ 5 mm for better grip and prevents chuck slipping.
- The 19-piece set includes drills with diameters:
- ⌀ 1 / 1.5 / 2 / 2.5 / 3 / 3.5 / 4 / 4.5 / 5 / 5.5 / 6 / 6.5 / 7 / 7.5 / 8 / 8.5 / 9 / 9.5 / 10mm.
