Sgs 51071 Carbide Jobber Drill Bit No. 71 0.026 in

Product Description

The SGS 51071 is a solid carbide jobber-length drill bit designed for precision drilling in composite materials and other demanding workpiece applications. Ground to a No. 71 wire gauge diameter of 0.026 inches (0.66 mm), the bit features a 118-degree faceted point angle for accurate self-starting entry with minimal walking. A web-thinned, tapered web design reduces thrust and improves chip evacuation. The bright uncoated finish is standard for solid carbide at this micro diameter. Intended for use by machinists, toolmakers, and trade professionals working with tight-tolerance holes in composites or similar substrates.

The SGS 51071 is suited for applications requiring small-diameter precision drilling in composite panels, circuit board materials, and lightweight structural components. At 1.0 inch overall length, this is a compact jobber-length tool optimized for stable short-reach drilling in CNC machine tools, drill presses, or precision hand-held fixtures. It conforms to DIN 338 standards and carries a Series 101 designation from SGS. Sold individually, it fits workflows where a single replacement bit is needed without a minimum bulk purchase.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance at micro diameters
• 118-degree faceted point with web thinning for reduced thrust and clean entry
• No. 71 wire gauge, 0.026-inch diameter with a tight tolerance of -0.0005 to 0.0000 inches
• Right-hand cut, regular spiral flute with 2 flutes for efficient chip clearance
• Straight-cylindrical shank, 0.026 inches in diameter, for standard collet or chuck mounting
• Conforms to DIN 338; designed for composite as the primary workpiece material

Compatibility

Designed as a DIN 338-compliant jobber-length drill bit for use in CNC machining centers, drill presses, and precision fixtures accepting a 0.026-inch straight shank. Primary workpiece material is composite per manufacturer specification.

Installation Notes

Installation and use of carbide micro-drill bits should be performed by qualified machinists or trade professionals familiar with small-diameter tooling. Ensure the spindle and chuck or collet are clean and true before seating the straight shank, as runout at this diameter will cause premature bit breakage. Power down and de-energize the machine before changing tooling. Avoid hand-pressure drilling applications where side-load forces cannot be controlled, as solid carbide is brittle at this diameter.
