Description

Performance and Engineering
According to DEWALT, the bits in this set are engineered for high-speed performance and longevity:
- High-Speed Steel (HSS): The metal drill bits are manufactured from hardened HSS according to DIN 338 standards, featuring a 118° point angle and a tapered section to ensure fast progress and a longer tool life.
- Precision Drilling: The wood bits are designed with a brad point (centering tip), two shoulders, and peripheral cutting edges for fast, clean, and accurate hole placement, making them ideal for dowel and through-hole applications.
- Masonry Capabilities: The masonry bits utilize advanced carbide-tipped technology to maintain fast drilling speeds and produce cleaner, concentric holes in materials like brick and light concrete.
- Spiral Groove Design: Precision-ground spiral grooves across the drill bits help maximize drilling progress and ensure excellent concentricity for clean holes.
