Product Description
The DEWALT ACCESSORIES DW1614 is a high-speed steel split point drill bit designed for professional drilling in metal, wood, and plastic. Measuring 0.5 inches in diameter and 12 inches in length, it features a 135-degree split point tip that starts on contact and eliminates bit walking without a center punch. The 31-degree helix angle moderates flute aggressiveness, striking a balance between aggressive chip removal and controlled cutting. A black oxide coating adds wear resistance, extending service life in demanding applications. This bit is industrial-grade tooling suited for electricians, plumbers, HVAC technicians, and general contractors who drill large-diameter holes through structural materials.
This drill bit is built for heavy-duty field and shop use where a full 12-inch reach is required. Typical applications include drilling through deep structural lumber, metal studs, pipe hangers, electrical enclosures, and similar trade materials. The parabolic flute geometry improves chip ejection, reducing heat buildup and clogging during continuous drilling in both ferrous metal and wood. Each package contains 5 bits, making it practical for crew stocking. The bit is compatible with standard 1/2-inch keyed or keyless drill chucks.
Key Features

- Parabolic flute design improves chip ejection in metal and wood drilling applications
- Black oxide coating improves wear resistance and extends bit life
- Industrial-grade high-speed steel construction for demanding trade use
- 12-inch length provides extended reach for deep drilling applications
Compatibility
Designed for use with standard 1/2-inch chuck drills. Suitable for drilling in metal, wood, and plastic across residential and commercial trade applications.
Installation Notes
This bit is installed and operated by any trade professional using a standard corded or cordless drill with a 1/2-inch chuck. Ensure the bit is fully seated and the chuck is tightened before operation. Use appropriate cutting fluid when drilling ferrous metals to reduce heat and extend bit life. Wear appropriate eye and hand protection in accordance with applicable jobsite safety standards.
