DEWALT 1627 Black Oxide Reduced Shank Drill Bit 7/8 Inch HSS 1/2 Inch Shank

The DEWALT DW1627 is a professional-grade high-speed steel (HSS) drill bit designed for drilling large diameter holes with standard 1/2-inch drill chucks. This reduced shank bit features a 7/8-inch cutting diameter with a 1/2-inch shank, allowing you to drill holes larger than 1/2-inch using conventional drills without requiring a larger chuck capacity.

Key Features:

• Black oxide coating provides superior wear resistance and helps prevent rust
• 135-degree split point tip design drills on contact and prevents walking for accurate hole placement
• Parabolic flute design with 31-degree helix angle improves chip ejection in metal and wood drilling applications
• Tapered web design delivers extreme durability to resist breakage under demanding conditions
• 3-flats shank reduces spin-out in the chuck for secure bit retention
• High-speed steel construction for drilling through metal, wood, and plastic

This reduced shank drill bit is ideal for general purpose applications including drilling in non-ferrous metals, wood, and plastics. The black oxide finish enhances bit life while the parabolic flute geometry ensures efficient material removal. Perfect for professional contractors, fabricators, and serious DIYers who need to drill large diameter holes with standard equipment.
