Cleveland C11682 Jobber Drill Bit Wire 28 Hss 135

Product Description

The CLEVELAND C11682 is a jobber length drill bit in wire gauge size 28, measuring 0.1405 inches in diameter with a 135-degree split point and a bright, uncoated high speed steel body. Designed for right-hand, spiral-flute cutting, this bit produces clean entry holes with reduced walking and less hand pressure required at the point. The web-thinned, tapered web design lowers cutting resistance, making it well suited for production drilling where consistency across multiple holes matters. Rated as heavy duty per NAS 907 Type B standards, it is appropriate for tradespeople and machinists who need reliable, repeatable performance from a small-diameter bit.

The C11682 is built for drilling aluminum as its primary workpiece material, though its high speed steel construction handles a broad range of non-ferrous and softer ferrous materials in typical shop and field applications. With an overall length of 2.875 inches and a flute length of 1.75 inches, it fits standard three-jaw drill chucks on corded and cordless drills, drill presses, and CNC machining centers used in HVAC fabrication, electrical panel work, sheet metal work, and general mechanical assembly. It ships as a single bit per package with no minimum order restriction.

Key Features

• Wire size 28 diameter: 0.1405 inches with tight tolerance of -0.0007 to 0.0000 inches for consistent hole sizing
• 135-degree split point reduces walking on contact and lowers thrust force needed at entry
• Web-thinned, tapered web construction reduces cutting resistance for faster penetration
• Bright, uncoated high speed steel finish allows easy visual inspection for wear and regrinding
• Straight-cylindrical shank fits standard drill chucks without adapters
• Meets NAS 907 Type B specification for heavy duty, repeatable performance

Compatibility

Designed as a standard jobber length drill bit for use with any drill press, hand drill, or CNC spindle accepting a straight-cylindrical shank of 0.1405 inches; fits three-jaw chucks and collet systems used in metalworking and mechanical trade applications.

Installation Notes

A licensed machinist or qualified tradesperson should secure the bit firmly in the chuck before operation and verify chuck key removal before powering the tool. Always wear eye protection and use appropriate cutting fluid or coolant when drilling metal, even though this bit does not have through-coolant capability. Do not exceed the rated speed range for the bit diameter and workpiece material as specified in the machine manufacturer or tooling reference charts. Inspect the cutting edges before each use and discard or regrind if chipping or dulling is visible.
