2-PACK DEWALT 5/16 in. x 12 in. Black Oxide Drill Bit DW1608

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.

• 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-degree which minimizes the over aggressiveness of a true parabolic flute
