Hertel 84577915 Jobber Drill Bit Letter G Hss 118 Deg

Product Description

The HERTEL 84577915 is a jobber-length drill bit sized to Letter G (0.2610 inches) and manufactured from high speed steel (HSS). It features a standard 118-degree point angle with a web-thinned, tapered web configuration for improved chisel-edge penetration on center starts. The straight-cylindrical shank measures 0.2610 inches in diameter and fits standard drill chucks without adapters. The bright, uncoated finish maintains tight dimensional tolerances straight from the factory. At 4.125 inches overall length with a 2.875-inch spiral flute, this is a general-purpose jobber geometry suited for production and maintenance drilling in metal, wood, and plastics.

This bit is used in general-purpose drilling applications across metalworking, mechanical maintenance, HVAC installation, plumbing rough-in, and electrical trade work where a Letter G hole diameter is required. The right-hand, regular-spiral, two-flute design handles ferrous and non-ferrous materials in both handheld and drill-press setups. Typical applications include tap drilling, clearance holes, and pilot holes in light fabrication and field service environments where a reliable HSS bit is the practical choice.

Key Features

• Letter G size — 0.2610 inches decimal equivalent for precise hole sizing
• 118-degree standard point angle with web-thinned, tapered web for easier center engagement
• High speed steel construction for general-purpose cutting in metal, wood, and plastic
• Bright uncoated finish preserves close dimensional accuracy out of the package
• Straight-cylindrical shank fits standard 3-jaw drill chucks without a reduction sleeve
• Two-flute regular spiral geometry promotes efficient chip evacuation in through-hole drilling

Compatibility

Designed as a general-purpose jobber-length drill bit for use in any standard drill press, handheld power drill, or drill motor accepting a straight-cylindrical shank in the 0.2500 to 0.3000 inch diameter range.

Installation Notes

Install in a properly rated drill chuck and tighten with a chuck key before operation. Ensure the workpiece is secured with a clamp or vise — never hold freehand when drilling metal. Apply appropriate cutting fluid when drilling ferrous materials to extend tool life and maintain hole quality. Follow applicable shop safety standards and wear eye protection at all times during drilling operations.
