Cleveland C11658 Jobber Drill Bit Wire 4 Hss 135 Deg

Product Description

The CLEVELAND C11658 is a jobber-length drill bit designed for precision drilling in metal and non-ferrous materials. Built from high speed steel with a bright uncoated finish, this bit features a 135-degree split point that reduces walking on entry and minimizes thrust force. The web-thinned, tapered web design improves chip evacuation and cutting efficiency. At 3.75 inches overall length with a 1.25-inch flute length, the C11658 covers standard jobber-length drilling tasks across a range of production and maintenance applications. It carries a 0.2090 inch diameter and conforms to NAS 907 Type B standards, making it a heavy-duty option for consistent, repeatable results.

This bit is suited for drilling aluminum and similar non-ferrous workpiece materials in both shop and field environments. The straight cylindrical shank fits standard drill chucks without modification. The regular spiral flute and right-hand cut make it a direct fit for conventional drilling setups. Machinists, maintenance technicians, pipefitters, and general tradespeople will find this bit appropriate for production drilling, fixture work, and general hole-making tasks where dimensional accuracy matters. It is sold individually and carries no minimum order beyond one unit.

Key Features

Compatibility

Designed as an OEM-style jobber-length replacement drill bit for use in standard drill chucks accepting a 0.2090 inch straight cylindrical shank, consistent with Series 2222 wire-gauge bits in the number 4 size range.

Installation Notes

Installation is performed by machinists or maintenance tradespeople using standard drill press or hand-drill equipment. Secure the shank fully in the chuck before operation and verify chuck key removal before powering the tool. Always use appropriate cutting fluid or lubricant when drilling metal to extend bit life and maintain hole quality. Inspect the cutting edges and point before each use and replace or resharpen if chipping or dulling is evident.
