Dewalt DW1634 Self Feed Bit 1-1/2 Inch

Product Description

The DEWALT DW1634 is a 1-1/2 inch self feed bit designed for fast, aggressive boring through wood framing, sheathing, and dimensional lumber. Self feed bits use a center screw point to pull the bit through the material, reducing the effort required from the operator and allowing for consistent, clean holes. This bit is a go-to tool for electricians, plumbers, and HVAC installers who need to drill large-diameter holes through structural members during rough-in work. The DW1634 is driven by a standard 7/16 inch hex shank and is compatible with most corded and cordless drill/drivers and right-angle drills used in trade applications.

The DW1634 is well suited for residential and light commercial rough-in work where 1-1/2 inch diameter penetrations are required through wood studs, joists, and plates. Electricians running conduit or cable, plumbers routing supply or drain lines, and HVAC techs pulling refrigerant lines or low-voltage wiring through framing will find this bit appropriate for their workflow. It is sold individually, making it a practical single-replacement option when a bit is worn or damaged on the job.

Key Features

• 1-1/2 inch cutting diameter for large-bore rough-in penetrations
• Center screw point self-feeds through wood, reducing operator push force
• Designed for use in wood framing, dimensional lumber, and sheathing

Compatibility

Designed as an OEM-style replacement self feed bit for use with standard hex-shank drill/drivers and right-angle drills commonly used in electrical, plumbing, and HVAC rough-in applications.

Installation Notes

Self feed bits are installed and removed by hand into any 7/16 inch hex chuck — no tools required for bit changes. Always confirm the drill is powered off and the chuck is secure before beginning a bore. When drilling through framing near existing wiring or piping, verify clearances before starting. Follow applicable NEC, IPC, or IFGC guidelines for minimum clearances when drilling holes in structural members for trade rough-in work.
