Cleveland C03079 Jobber Length Drill Bit Letter G Hss

Product Description

The CLEVELAND C03079 is a jobber-length drill bit sized to letter G (0.2610 inches), ground from high speed steel with a bright, uncoated finish. It features a 118-degree standard point angle, a fast spiral flute, and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The straight-cylindrical shank measures 0.2610 inches in diameter and 1.25 inches in length, while the overall length is 4.125 inches with a flute length of 2.875 inches. It is manufactured to ASME B94.11M standards and carries a general-purpose grade rating. Licensed HVAC technicians, machinists, pipefitters, and general trade professionals install this bit in standard drill chucks for through-hole and pilot operations.

The C03079 is suited for drilling aluminum and similar non-ferrous or soft ferrous workpiece materials in both residential and light commercial trade applications. Its fast spiral promotes efficient chip clearing in softer materials, reducing heat buildup and extending tool life during repetitive drilling tasks. With a diameter tolerance of -0.0010 to 0.0000 inches, it holds close sizing for consistent hole quality across production or service-call drilling scenarios. This bit ships as a single unit and is well matched to hand drills, drill presses, and portable mag-base drills common on job sites.

Key Features

• 118-degree standard point angle with web-thinned, tapered web for reduced thrust on entry
• Fast spiral flute design promotes aggressive chip evacuation, especially in aluminum and soft metals
• High speed steel construction with bright, uncoated finish — no coating to chip or delaminate
• Right-hand cut, 2-flute configuration; straight-cylindrical shank fits standard drill chucks
• Manufactured to ASME B94.11M standards under Cleveland Series 2012

Compatibility

Designed as an OEM-style general-purpose jobber drill bit for use in any standard drill chuck accepting a 0.2610-inch straight-cylindrical shank. Primary workpiece material rating is aluminum; also suitable for general-purpose drilling in compatible soft to medium-hardness materials as appropriate for high speed steel tooling.

Installation Notes

Secure the shank fully in a keyed or keyless drill chuck before operation and verify chuck tightness before applying power. Use appropriate cutting fluid or lubricant when drilling metals to extend tool life and maintain hole tolerance. Inspect the cutting edges before each use — a chipped or dull point will produce oversized, rough holes and should be resharpened or replaced. Wear ANSI-rated eye protection and follow applicable shop or job-site safety procedures when operating rotary cutting tools.
