Sgs 51076 Jobber Drill Bit Wire 76 Solid Carbide

Product Description

The SGS 51076 is a solid carbide jobber-length drill bit sized to wire gauge 76, equivalent to 0.02 inch (0.51 mm) diameter. Built to DIN 338 standards, it features a 118-degree faceted point angle and a two-flute spiral configuration with a web-thinned, tapered web for improved chip evacuation and reduced thrust at entry. The bright, uncoated micrograin carbide construction delivers hardness and edge retention suitable for small-diameter drilling in demanding materials. Overall length is 7/8 inch with a 1/4-inch flute length. Installation and operation are performed by machinists and tooling professionals working in precision fabrication environments.

The 51076 is designed primarily for drilling composite workpiece materials, though micrograin solid carbide construction makes it well-suited to other applications requiring tight tolerances and a sharp, stable cutting edge in small wire-gauge sizes. The right-hand spiral flute and straight-cylindrical shank allow direct chuck mounting in standard drill presses, CNC machining centers, and hand-held precision drilling equipment. The 5xD flute-to-diameter ratio supports controlled chip clearance in shallow-depth applications typical of wire-gauge drilling work.

Key Features

• Wire gauge 76 sizing: 0.02 inch (0.51 mm) diameter for precision small-hole applications
• 118-degree faceted point angle with web-thinned tapered web reduces walking and entry thrust
• Solid micrograin carbide construction provides hardness and dimensional stability
• Two-flute regular spiral design promotes efficient chip evacuation
• Bright, uncoated finish maintains as-ground surface for close-tolerance work
• Conforms to DIN 338 standards; diameter tolerance held to -0.0005 to 0.0000 inch

Compatibility

Designed as an OEM-style replacement or direct-application drill bit for operations requiring wire gauge 76 hole sizing in composite and similar materials; compatible with standard straight-shank drill chucks accepting 0.02-inch shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with small-diameter carbide tooling. Always ensure the drill press or machining center spindle is fully stopped and de-energized before changing or securing tooling. Carbide bits are brittle compared to high-speed steel; avoid lateral loading or flex during operation. Verify chuck runout is within acceptable limits before drilling at this diameter to prevent bit breakage.
