Sgs 53023 Solid Carbide Jobber Drill Bit No.23 0.154 in

Product Description

The SGS 53023 is a solid carbide jobber-length drill bit in wire gauge size 23, equivalent to 0.154 inches (3.91 mm) in diameter. It features a 150-degree drill point angle and a three-flute regular spiral configuration, making it well suited for high-performance drilling in demanding materials. The micrograin carbide construction delivers the hardness and heat resistance required when working in cast iron, hardened steel, and non-ferrous metals. The bright uncoated finish and web-thinned, tapered web design reduce entry force and chip buildup. Licensed HVAC techs, machinists, and metalworking tradespeople will find this bit appropriate for precision hole work in tight tolerances.

This bit is sized for production and maintenance drilling in ferrous and non-ferrous materials across industrial and commercial shop environments. Its 2.5-inch overall length and 1.375-inch flute length make it a compact, jobber-class tool for benchtop drill presses, CNC machines, and hand-held drilling equipment. Typical applications include drilling in cast iron components, hardened steel fixtures, and general-purpose metal fabrication work requiring consistent, repeatable hole geometry. The straight cylindrical shank fits standard drill chucks without adapters.

Key Features

• Solid micrograin carbide construction for superior hardness and wear resistance in hard metals
• 150-degree drill point angle reduces thrust and improves entry on hard or abrasive materials
• Three-flute spiral design promotes efficient chip evacuation and improved hole finish
• Web-thinned tapered web lowers cutting resistance and entry force
• Bright uncoated finish maintains full carbide substrate performance without coating delamination risk
• Diameter tolerance of +0.0000 to -0.0005 inches ensures precise, consistent hole sizing

Compatibility

Designed as an OEM-style jobber-length drill bit for use in standard straight-shank drill chucks on drill presses, machining centers, and CNC equipment. Compatible with cast iron, hardened steel, non-ferrous metal, and general steel workpiece materials as specified by the manufacturer. Conforms to DIN 6539 standards.

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 drill chuck before operation to prevent runout. Carbide bits are brittle and susceptible to chipping from side loads or impact - avoid using in hammer-drill mode or on unstable workpieces. Follow applicable shop safety codes and manufacturer feed-and-speed guidelines for carbide tooling in the workpiece material being drilled.
