Sgs 51050 Jobber Length Drill Bit Wire 50 Solid Carbide

Product Description

The SGS 51050 is a jobber-length drill bit sized to wire gauge No. 50, with a decimal diameter of 0.0700 inches and an overall length of 1-3/4 inches. It is manufactured from micrograin solid carbide with a bright, uncoated finish. The bit features a 118-degree faceted drill point, a two-flute right-hand spiral configuration, and a web-thinned, tapered web design that reduces entry force and helps center the bit on the workpiece. The straight-cylindrical shank matches the bit diameter at 0.0700 inches. This is a Series 101 tool built to DIN 338 standards and is installed by machinists, toolroom technicians, and composite fabricators.

The SGS 51050 is engineered for drilling composite materials, making it well suited to aerospace, electronics, and industrial fabrication environments where small-diameter precision holes are required. The 5xD flute-to-diameter ratio and 7/8-inch flute length support consistent chip evacuation in shallow-to-moderate drilling depths up to 0.7031 inches. The bright finish is appropriate for composite substrates where coating adhesion or heat transfer to the workpiece is a concern. This bit ships individually and is suited for use in drill presses, CNC machining centers, and hand-held precision drilling equipment.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in composite drilling
• 118-degree faceted point with web thinning for reduced thrust and accurate hole placement
• Bright, uncoated finish compatible with composite and non-ferrous workpiece materials
• Right-hand cut, two-flute spiral design promotes efficient chip clearance
• Straight-cylindrical shank for standard drill chucks and collet holders
• Manufactured to DIN 338 standard; diameter tolerance of -0.0005 to 0.0000 inches

Compatibility

Designed as an OEM-style replacement or direct-fit option for applications requiring a wire gauge No. 50 solid carbide jobber-length drill bit conforming to DIN 338 dimensions. Primary workpiece material is composite; the geometry is not optimized for hardened steel or cast iron.

Installation Notes

This bit should be installed and operated by a qualified machinist or toolroom technician familiar with small-diameter carbide tooling. Secure the shank fully in a precision drill chuck or collet before operation and confirm runout is within acceptable limits, as carbide is brittle and sensitive to lateral deflection. Do not use in impact drivers or hammer-drill mode. Power down and de-energize the machine spindle completely before changing tooling.
