Sgs 51107 Jobber Drill Bit 7/64 Inch Solid Carbide

Product Description

The SGS 51107 is a jobber-length drill bit designed for precision drilling in demanding shop and field applications. Built from micrograin solid carbide with a bright uncoated finish, this bit delivers the hardness and edge retention required for drilling ferrous and non-ferrous metals, plastics, and composites. It measures 7/64 inch (0.1094 inch decimal) in diameter with a 118-degree faceted point and a right-hand spiral flute. Overall length is 2-1/4 inches, with a 1-1/4 inch flute length and a maximum recommended drilling depth of 1.000 inch. The straight cylindrical shank seats directly in standard chucks without adapters. This bit is appropriate for machinists, tool and die techs, maintenance mechanics, and precision fabricators.

The SGS 51107 fits general-purpose jobber-length drilling applications where dimensional accuracy and tool life are priorities. The micrograin carbide construction holds up in higher-speed operations compared to high-speed steel alternatives. The web-thinned, tapered-web geometry reduces thrust and improves chip evacuation in through-hole and blind-hole work. Series 101 covers the 0.1000 to 0.1500 inch diameter range, and this bit sits at the lower end of that range at 7/64 inch. Typical use cases include CNC machining centers, drill presses, and hand-held power drills equipped with keyless or keyed chucks sized for small-diameter tooling.

Key Features

• Micrograin solid carbide construction for extended tool life and edge retention
• 118-degree faceted point with web thinning reduces entry thrust and improves centering
• Tapered web configuration promotes efficient chip evacuation in spiral flutes
• Bright uncoated finish maintains consistent diameter tolerance of -0.0005 to 0.0000 inch
• Straight cylindrical shank compatible with standard drill chucks — no adapter required
• Conforms to DIN 338 jobber-length standard for predictable dimensional consistency

Compatibility

Designed as an OEM-style replacement or direct-fit drill bit for any application requiring a DIN 338 jobber-length, 7/64 inch straight-shank carbide drill bit with a 118-degree point.

Installation Notes

This bit is installed by machinists and maintenance professionals using standard drill presses, CNC machining centers, or handheld power drills. Secure the shank fully in the chuck and verify runout before drilling to protect the small-diameter carbide from lateral stress. Carbide is brittle — avoid side loading, interrupted cuts without proper feed rate adjustment, and re-sharpening attempts without appropriate carbide grinding equipment. Always follow applicable shop safety procedures and machine manufacturer guidelines for small-diameter tooling.
