Diablo DSF2125 Self-feed Bit 2-cutter 2-1/8 in

Product Description

The DIABLO DSF2125 is a 2-cutter self-feed bit engineered for fast, efficient hole-making in soft woods and clean construction lumber. Heat-forged from premium steel, it features an aggressive low-thread-count feed screw that reduces pitch build-up and drives faster entry into the material. The 2-cutter head delivers consistent, smooth cuts with minimal resistance and clean finishes. Designed for use with cordless drills, this bit is built for tradespeople who need reliable performance over extended drilling sessions without sacrificing hole quality or tool life.

The DSF2125 is sized at 2-1/8 inches in diameter and 5-1/8 inches in length, making it well-suited for rough-in drilling tasks in residential and light commercial framing applications. Plumbers, electricians, and framers use this bit when running pipe, conduit, or wire through wood framing members. It is optimized for softwood and clean construction lumber and is designed to be driven by standard cordless drills. Each bit ships with a replacement feed screw and an Allen key included in the package.
