Cle-line C18440 7/32 in Jobber Drill Bit 135 Hss

Product Description

The CLE-LINE C18440 is a jobber-length drill bit designed for precision hole-making in a wide range of materials. Built from high speed steel with a gold oxide coating, this bit features a 135-degree split point and parabolic flute geometry for fast chip evacuation and reduced walking on entry. The overall length is 3.75 inches with a flute length of 2.5 inches and a straight cylindrical shank at 7/32 inch diameter. Rated as heavy duty and web-thinned, it delivers consistent performance across production and maintenance drilling operations. Fabricators, machinists, and maintenance technicians are the primary users.

The C18440 is sized at 7/32 inch (0.2188 inch decimal) and is optimized for drilling aluminum and non-ferrous metals, as indicated by its primary workpiece material codes. The parabolic flute design handles deep-hole drilling efficiently by pulling chips out of the cut zone before they pack. The gold oxide finish provides mild lubricity and corrosion resistance during storage and use. This bit is suited for use in drill presses, hand drills, and CNC machines in light industrial, fabrication, and field service environments.

Key Features

• 135-degree split point reduces walking and cutting force at entry
• Parabolic flute geometry accelerates chip evacuation in deep holes
• Gold oxide coating provides surface lubricity and corrosion protection
• Web-thinned with tapered web configuration for reduced thrust requirements
• Straight cylindrical shank fits standard drill chucks without adapters
• Meets ASME B94.11M and DIN 338 standards for jobber-length drill bits

Compatibility

Designed as an OEM-style jobber-length drill bit compatible with standard 3-jaw drill chucks accepting a 7/32 inch straight cylindrical shank. Primary workpiece material codes indicate suitability for aluminum, non-ferrous metals, and plastics (material codes K, N, P).

Installation Notes

Install in a properly sized drill chuck and tighten securely before operation. Power down and lock out any machine before changing bits. Use appropriate cutting fluid or lubricant when drilling metals to extend bit life and maintain hole tolerance. Inspect the cutting edges for wear or chipping before each use, as a dull split-point tip increases the risk of workpiece damage and bit breakage.
