Sgs 51203 Jobber Drill Bit Letter C 0.2420 in Solid Carbide

Product Description

The SGS 51203 is a jobber-length drill bit designed for precision hole-making in metalworking and machining applications. Ground from solid micrograin carbide, it delivers the rigidity and edge retention needed for drilling hard and abrasive materials. The bit measures 0.2420 inches (Letter C) in diameter with an overall length of 3.25 inches and a flute length of 2 inches. The 118-degree faceted point angle with web thinning reduces entry force and improves centering. A bright, uncoated finish is standard. This bit is installed and operated by machinists, tool-and-die professionals, and skilled maintenance technicians.

The SGS 51203 is suited for production and maintenance drilling in machine shops, manufacturing facilities, and industrial maintenance environments. It is appropriate for use in drill presses, CNC machining centers, and hand-held drilling equipment where a straight-shank, jobber-length carbide bit is required. The Series 101 designation places this bit within SGS's standard jobber-length solid carbide line, making it a direct-use replacement or stock-up item for shops that run Letter C diameter holes routinely.

Key Features

• Solid micrograin carbide construction for extended tool life in hard materials
• 118-degree faceted point with web thinning for reduced thrust and accurate entry
• Regular right-hand spiral flute with 5xD flute-to-diameter ratio for efficient chip evacuation
• Straight cylindrical shank at 0.2420 inches for standard chuck compatibility
• Bright uncoated finish suitable for use with or without cutting fluid
• Conforms to DIN 338 standard for jobber-length drill geometry

Compatibility

Designed as a standard jobber-length drill bit with a straight cylindrical shank; compatible with any drill chuck or collet system that accepts a 0.2420-inch straight shank.

Installation Notes

Installation is performed by machinists or maintenance technicians using a drill press, milling machine, or CNC machining center. Secure the shank fully in a properly sized chuck or collet before operation. Carbide tooling is brittle — avoid side loading, interrupted cuts without proper support, or dropping the bit on hard surfaces. Always bring spindle to a full stop before changing tooling.
