Sgs 51018 Solid Carbide Jobber Drill Bit No. 18 Wire

Product Description

The SGS 51018 is a solid carbide jobber length drill bit designed for precision drilling in demanding shop and field applications. Built from micrograin solid carbide, this bit delivers consistent performance in ferrous and non-ferrous metals, plastics, and composite materials. It features a 118-degree faceted point angle with web thinning for reduced thrust and improved chip evacuation. The two-flute spiral design with a regular helix supports efficient cutting in general-purpose drilling operations. At 2.75 inches overall length with a 1.625-inch flute length, it fits standard drill chucks used by machinists, toolmakers, and maintenance technicians.

The SGS 51018 is suited for production and maintenance drilling in metalworking environments, fabrication shops, and general industrial settings. The No. 18 wire size (0.1695 inches) is a common call-out for tapping undersize holes and close-tolerance drilling work. The straight cylindrical shank fits standard Jacobs-style and keyless drill chucks. It is sold and packaged as a single unit, making it practical for tool crib restocking or single-job procurement.

Key Features

• Micrograin solid carbide construction for extended tool life in hard and abrasive materials
• 118-degree faceted point with web thinning for reduced entry thrust and better self-centering
• Two-flute regular spiral design promotes efficient chip clearance
• Bright uncoated finish suitable for applications where coating buildup is a concern
• Meets DIN 338 standard for jobber length drill geometry
• Tapered web configuration adds strength at the cutting tip

Compatibility

Designed as an OEM-style replacement and standard tooling option for general-purpose drilling applications requiring a No. 18 wire size (0.1695 inches) solid carbide jobber length drill bit.

Installation Notes

Install and remove only with the spindle at a complete stop. Secure the straight cylindrical shank firmly in a properly sized drill chuck before operation. Machinists and toolroom technicians should verify chuck runout before use, as excessive runout accelerates carbide tip wear. This bit does not support coolant-through delivery; use external coolant or cutting fluid as appropriate for the workpiece material.
