Dewalt Accessories DW1634 Self-feed Bit 1-1/2 Inches

Product Description

The DEWALT ACCESSORIES DW1634 is a 1-1/2-inch self-feed bit engineered for fast, aggressive wood boring in rough-in applications. The bit uses an optimized cutting geometry that increases drilling speed while extending service life compared to standard spade-style bits. An open-tooth design allows field resharpening without special equipment, keeping the bit productive over repeated use cycles. A 7/16-inch ball groove shank provides compatibility with quick-change chuck systems, reducing tool swap time on busy job sites. This bit is a standard choice for licensed plumbers and contractors drilling large-diameter holes through framing and structural members for pipe runs.

The DW1634 is suited for residential and light commercial rough-in work where plumbers, electricians, or general contractors need to bore clean, fast holes through wood framing, joists, and studs. It is packaged in a quantity of 5 per unit, making it practical for high-volume drilling tasks such as multi-story pipe chases or electrical conduit runs. The aggressive spur geometry initiates the cut quickly and helps maintain hole position on angled or difficult surfaces.

Key Features

Compatibility

Designed for use with power drills and right-angle drill drivers equipped with a 7/16-inch quick-change or hex chuck. Suitable for boring through dimensional lumber, engineered wood, and similar wood framing materials in rough-in installations.

Installation Notes

Self-feed bits are typically installed and used by licensed plumbers, electricians, and framing contractors performing rough-in work. Always confirm the drill driver is capable of handling the torque demands of a self-feed bit before use. Secure the workpiece before drilling and keep clear of the bit path. Inspect the spur and cutting edges before each use and resharpen or replace as needed to maintain clean hole geometry.
