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° split point for enhanced hole-drilling performance, including quick starts and clean, burr-free holes. For use in wood, metal, plastics and fiberglass.
135° 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° which minimizes the over aggressiveness of a true parabolic flute
