Sgs 51053 Jobber Drill Bit No. 53 Wire Solid Carbide

Product Description

The SGS 51053 is a solid micrograin carbide jobber-length drill bit sized to wire gauge No. 53 (0.0595 inches decimal, 1.51 mm). It features a 118-degree faceted point with web thinning for clean entry and reduced thrust. The spiral flute with regular helix and tapered web configuration supports efficient chip evacuation. Overall length is 1.5 inches with a 0.75-inch flute length and a straight-cylindrical shank. The bright uncoated finish is suited for applications where a base carbide surface is preferred. This bit is designed for use by machinists, aerospace technicians, and trade professionals drilling small-diameter holes in composite materials and similar workpieces.

The SGS 51053 is intended for precision small-diameter drilling in composite materials, making it a fit for aerospace, electronics assembly, and specialty fabrication work. The 5xD flute-to-diameter ratio and right-hand cut suit controlled, low-runout setups. It is sold and packaged individually. The Series 101 designation places it within the SGS standard jobber drill lineup, appropriate for both manual drill press use and CNC drilling operations where tight hole tolerances are required.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance in composite and abrasive materials
• 118-degree faceted point with web thinning reduces entry thrust and improves hole accuracy
• Spiral regular-helix flute design promotes chip clearance in small-diameter drilling
• Straight-cylindrical shank compatible with standard collets and chucks
• Bright uncoated finish with diameter tolerance of -0.0005 to 0.0000 inches
• Conforms to DIN 338 standard for jobber-length drill geometry

Compatibility

Designed as a DIN 338 jobber-length drill bit for use in drill presses, CNC machining centers, and hand-held drill applications requiring a No. 53 wire-gauge hole in composite or similar workpiece materials.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with small-diameter carbide tooling. Secure the shank fully in the collet or chuck to minimize runout before drilling. Carbide tooling is brittle - avoid side loading, interrupted cuts without proper feeds and speeds, or dropping the bit. Power down and lock out the machine before changing tooling.
