Description

Product Overview

The Cle-line C21165 mechanics length drill bit set is engineered for professionals who demand precision, durability, and speed on every job site. Constructed from 1875R high speed steel (HSS), each bit maintains a sharp cutting edge even under high torque and elevated temperatures, reducing the need for frequent replacements. The set spans a comprehensive size range from 1/16 inch to 1/2 inch, covering the most common diameters required for metal, wood, and composite applications. A distinctive black and gold barrel finish not only adds a premium visual cue but also resists corrosion, wear, and the buildup of debris that can impair performance. The bits are housed in a sturdy, compact barrel that keeps them organized, protects the cutting edges, and makes quick retrieval effortless during fast‑paced projects.

The bits’ high speed steel composition allows them to cut through hardened steel, stainless steel, and treated lumber with minimal wobble, ensuring clean, accurate holes that meet industry tolerances. The ergonomic barrel design enables technicians to carry the entire set in a tool belt or toolbox, keeping essential sizes within arm’s reach for on‑site adjustments.
