Sgs 51061 Jobber Drill Bit Wire 61 Solid Carbide 118 Deg

Product Description

The SGS 51061 is a solid carbide jobber-length drill bit in wire gauge size 61, with a decimal diameter of 0.039 inches. It features a 118-degree faceted point angle and a two-flute right-hand spiral configuration suited for precision drilling in tight tolerances. The bright uncoated micrograin carbide construction provides rigidity and edge retention where smaller high-speed steel bits would deflect or wear prematurely. Overall length is 1.375 inches with a 0.625-inch flute length and a straight cylindrical shank. This bit is intended for use by machinists, tool and die technicians, and maintenance professionals working with composite materials or other demanding substrates.

The SGS 51061 is designed for applications requiring small-diameter precision drilling in composite workpieces. Its 5xD flute-to-diameter ratio and tapered web configuration with web thinning reduce thrust and improve chip evacuation in shallow-to-moderate-depth holes. Typical install scenarios include aerospace component drilling, electronics board work, and precision fixture fabrication where a wire-gauge drill is required. This bit is sold individually and is appropriate for both CNC and hand-held precision drilling equipment.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in composite and hard materials
• 118-degree faceted point with web thinning reduces entry thrust and improves centering
• Two-flute right-hand spiral with 5xD ratio supports efficient chip evacuation
• Bright uncoated finish suitable for applications where coatings may affect dimensional tolerance
• Straight cylindrical shank with 0.039-inch diameter for standard collet or chuck mounting
• Conforms to DIN 338 standard for jobber-length drill geometry

Compatibility

Designed as an OEM-style replacement or direct-use jobber-length drill bit for applications requiring wire gauge size 61 at 0.039 inches decimal diameter, compatible with standard straight-shank collets and drill chucks accepting shanks in the 0.039-inch range.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with small-diameter carbide tooling. Carbide bits are brittle and must be handled carefully to avoid chipping the cutting edge before use. Ensure the spindle and chuck or collet are clean and concentric before seating the shank to avoid runout that can snap small-diameter carbide. Do not use excessive feed pressure; allow the geometry and spindle speed appropriate for carbide tooling in the workpiece material to do the work.
