Cle-line C18071 Jobber Drill Bit Wire Size 18 Hss

Product Description

The CLE-LINE C18071 is a wire size 18 jobber-length drill bit designed for heavy-duty metal drilling applications. It is manufactured from high-speed steel (HSS) with a black and gold oxide coating that helps reduce friction and extend tool life. The split-point, web-thinned tip at 135 degrees starts on contact without a center punch, reducing walking on flat surfaces. At 3.25 inches overall length with a 2.125-inch flute, this bit handles typical through-hole and blind-hole work in steel and cast iron. Licensed tradespeople and machinists are the primary users of this bit in production and service environments.

This jobber drill bit is suited for drilling steel, cast iron, and similar ferrous workpiece materials in both light manufacturing and field service settings. The straight cylindrical shank and 0.1695-inch diameter make it compatible with standard three-jaw drill chucks on corded drills, drill presses, and magnetic base drills. It is appropriate for residential and commercial mechanical, electrical, and plumbing rough-in work where clean, accurate holes in metal are required. The right-hand cutting direction and regular spiral flute provide efficient chip evacuation during standard drilling operations.

Key Features

• 135-degree split point starts on contact, reducing bit walking without a center punch

Compatibility

Designed as an OEM-style jobber drill bit in wire size 18 (0.1695 inches) for use with any standard drill chuck accepting a straight cylindrical shank of the same diameter.

Installation Notes

Installation of this drill bit is performed by electricians, plumbers, HVAC technicians, and general tradespeople using hand drills or drill presses. Secure the straight shank fully into the chuck and tighten all jaws evenly before operation. Always wear appropriate eye protection and secure the workpiece before drilling. Follow applicable workplace safety codes and equipment manufacturer guidelines for speed selection based on material and bit diameter.
