Cle-line C18614 Jobber Length Drill Bit 11.2mm Hss

Product Description

The CLE-LINE C18614 is a jobber length drill bit engineered for heavy-duty metal drilling applications. Built from high speed steel with an oxide/gold coating, it delivers consistent performance in production and maintenance environments. The bit measures 11.2 mm (0.4409 inches) in diameter with an overall length of 142 mm (5.59 inches) and a flute length of 94 mm (3.70 inches). The 135-degree split point reduces walking on contact, enabling accurate hole starts without a center punch. A parabolic flute profile clears chips efficiently, reducing heat buildup during deep-hole drilling.

This bit is suited for drilling operations in ferrous and non-ferrous metals, plastics, and composite materials in both shop and field settings. Its straight-cylindrical shank accepts standard drill chucks without adapters. The heavy-duty grade designation makes it appropriate for repetitive use in fabrication shops, mechanical contracting, and industrial maintenance work where consistent hole diameter and extended tool life are required.

Key Features

• 135-degree split point for accurate starts and reduced thrust force
• Parabolic flute geometry for fast chip evacuation in deep holes
• Oxide/gold coating for improved lubricity and wear resistance
• Web-thinned, tapered web construction reduces cutting resistance
• Straight-cylindrical shank fits standard keyless and keyed chucks
• Heavy-duty grade for high-cycle production and maintenance drilling

Compatibility

Designed as a standard jobber length drill bit with a straight-cylindrical shank, compatible with any drill chuck sized to accept an 11.2 mm (0.4409 inch) shank diameter.

Installation Notes

This bit is installed by machinists, maintenance technicians, and trade professionals using corded or cordless drills and drill presses equipped with a compatible chuck. Secure the shank fully in the chuck before operation and confirm the chuck is tightened at all three key positions on keyed chucks. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and maintain hole tolerance. Inspect the cutting edges for wear before each use and replace the bit if chipping or rounding is observed.
