Sgs 51022 Solid Carbide Jobber Drill Bit Wire Size 22

Product Description

The SGS 51022 is a solid carbide jobber-length drill bit designed for precision drilling in hard and abrasive materials. Ground from micrograin solid carbide, this bit delivers tighter tolerances and longer tool life compared to high-speed steel alternatives. It carries a wire gauge size of 22, equivalent to 0.157 inches (3.99 mm), with a 118-degree faceted point angle and a bright, uncoated finish. The two-flute regular spiral design promotes efficient chip evacuation in a wide range of materials, making it a reliable choice for machinists, tool-and-die technicians, and maintenance professionals working in production or job-shop environments.

This drill bit is suited for use in CNC machining centers, drill presses, and hand-held power tools where a straight-shank carbide bit is appropriate. It excels in harder workpiece materials such as cast iron, hardened steel, stainless steel, and non-ferrous alloys where carbide outperforms high-speed steel. The web-thinned, tapered-web construction reduces entry thrust and improves centering. At 2.5 inches overall length with a 1.375-inch flute length, it fits standard jobber-length chuck applications. This bit is sold individually and is part of SGS Series 101.

Key Features

• Micrograin solid carbide construction for extended tool life in hard and abrasive materials
• 118-degree faceted point angle for accurate self-starting entry and reduced walking
• Web-thinned, tapered-web design reduces thrust and improves chip flow at entry
• Right-hand cut, regular spiral flute geometry promotes consistent chip evacuation
• Diameter tolerance of -0.0005 to 0.0000 inches ensures close-fit hole accuracy
• Conforms to DIN 338 standard for jobber-length drill geometry

Compatibility

Designed as an OEM-style jobber-length drill bit conforming to DIN 338, suitable for use in standard straight-shank drill chucks across CNC machining centers, drill presses, and compatible power tools.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with carbide tooling. Secure the straight-cylindrical shank firmly in a properly sized chuck before operation and verify runout before drilling. Carbide bits are brittle compared to high-speed steel - avoid side loading, interrupted cuts without appropriate feed rates, or dropping the bit. Always match spindle speed and feed rate to the workpiece material and consult published carbide drilling parameters for the specific material being cut.
