Sgs 51044 Solid Carbide Jobber Drill Bit No. 44

Product Description

The SGS 51044 is a solid carbide jobber-length drill bit sized to No. 44 wire gauge, equivalent to 0.086 inches (2.18 mm) in diameter. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for drilling hard, abrasive, or work-hardening materials where high-speed steel would wear quickly. The 118-degree faceted point provides a reliable, self-centering entry without requiring a center punch on most setups. With a 2-inch overall length and a 1-inch spiral flute, this bit is well suited for precision drilling in tight or confined work areas. The bright, uncoated finish keeps tolerances tight, holding a diameter tolerance of -0.0005 to 0.0000 inches. It is designed for machinists, tool and die workers, and trade professionals who need consistent performance in small-diameter hole work.

The SGS 51044 fits standard CNC machining centers, drill presses, and hand-held precision drilling setups that accept a straight-cylindrical shank. Its No. 44 wire size makes it a common choice for tapping preparation, electrical panel work, sheet metal, and instrument fabrication. The 5xD flute-to-diameter ratio supports chip evacuation in moderate-depth drilling applications. Maximum recommended drilling depth is approximately 0.797 inches. This bit is sold individually and is appropriate for professional machine shop, maintenance, and fabrication environments.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• 118-degree faceted point angle with web-thinned, tapered web for reduced thrust and cleaner entry
• Bright uncoated finish with tight diameter tolerance of -0.0005 to 0.0000 inches
• Right-hand cut, 2-flute regular spiral geometry promotes consistent chip evacuation
• Straight-cylindrical shank fits standard drill chucks and collets without modification
• Conforms to DIN 338 standard for jobber-length drill bits

Compatibility

Designed as a DIN 338-compliant jobber-length drill bit for use in any drill press, CNC machining center, or precision hand drill accepting a straight-cylindrical shank sized at 0.086 inches. Suitable for the No. 44 wire gauge size range within the 0.0500 to 0.1000 inch drill bit diameter category.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with small-diameter carbide tooling. Carbide is brittle compared to high-speed steel - avoid side loading, interrupted cuts without proper support, and excessive feed rates that can cause chipping or breakage. Secure the shank fully in the chuck or collet before operation and verify spindle runout is within acceptable limits for the diameter. Always wear appropriate eye protection when operating rotary cutting tools.
