Dewalt Accessories DW1129 Black Oxide Drill Bit 29/64 in 2 Pack

Product Description

The DEWALT ACCESSORIES DW1129 is a 29/64 inch black oxide drill bit sold in a pack of two. It features a 135-degree split point tip that drills on contact, reducing bit walking and improving hole placement accuracy in metal, plastic, and wood. The patented core diameter design reduces breakage, and the tapered web construction adds durability through demanding applications. A no-spin shank prevents bit spin-out in the chuck during use. Black oxide coating resists rust and improves wear resistance for extended service life. This bit is a practical choice for trade professionals who drill into mixed materials regularly.

The DW1129 suits residential and light commercial applications where accurate, clean entry holes are required in metal, plastic, and wood substrates. Typical install scenarios include electrical rough-in work, plumbing bracket mounting, HVAC sheet metal penetrations, and general mechanical work. The 29/64 inch diameter is a common size for clearance holes and anchor pilot holes in light-gauge and structural materials. The two-pack format supports job-site redundancy without overstocking.

Installation Notes

Install and remove drill bits only when the drill is powered off and fully stopped. Secure the bit firmly in the chuck before drilling to prevent slippage. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and improve hole quality. Dispose of worn bits safely, as the black oxide coating does not indicate remaining service life.
