Tired of drill bits that dull quickly and snap under the slightest pressure? Then step up to DEWALT Black Oxide Drill Bits. These industrial-grade twist-drill bits are cut from super-hard, resilient black oxide for the ultimate in durability and strength. Each bit features a 135-degree split point for enhanced hole-drilling performance, including quick starts and clean, burr-free holes. For use in wood, metal, plastics and fiberglass.
- 14-piece black oxide drill bit set
- 135-degree split point drills on contact and prevents walking
- Parabolic flute design improves chip ejection in metal and wood drilling applications
- Black oxide-coated for greater wear resistance
- Helix is 31 degrees, which minimizes the over- aggressiveness of a true parabolic flute
