Sgs 53124 Jobber Length Drill Bit 3/8 Inch Solid Carbide

Product Description

The SGS 53124 is a solid carbide jobber length drill bit designed for precision drilling in demanding materials. Built from micrograin solid carbide with a bright/uncoated finish, this bit features a 150-degree point angle that reduces cutting force and improves centering on hard surfaces. The three-flute spiral design promotes efficient chip evacuation and helps maintain stable cutting action. At 3/8 inch (0.3750 inch) diameter and 4.25 inches overall length, it is sized for standard jobber-length applications. The web-thinned, tapered web construction reduces thrust requirements, making it well suited for tough ferrous and non-ferrous stock. This bit is installed by machinists, tool-and-die technicians, and maintenance professionals working in production or field environments.

The SGS 53124 is intended for drilling cast iron, hardened steel, non-ferrous metals, and general steel. The straight cylindrical shank allows use in standard drill chucks and collet holders on CNC machining centers, drill presses, and handheld power drills with appropriate chuck capacity. With a maximum drilling depth of 2.20 inches and a flute length of 2.75 inches, this bit handles a wide range of through-hole and blind-hole operations where solid carbide performance is required over high-speed steel alternatives.

Key Features

• 3/8 inch (0.3750 inch) diameter with diameter tolerance of -0.0005 to 0.0000 inch for precise hole sizing
• 150-degree point angle reduces entry force and improves self-centering on hard materials
• Three-flute regular spiral configuration for improved chip clearance versus two-flute designs
• Micrograin solid carbide construction delivers hardness and wear resistance in abrasive materials
• Web-thinned tapered web lowers thrust load during drilling operations
• Conforms to DIN 6539 standard; Series 103 designation

Compatibility

Designed for use in standard drill chucks and collet systems accepting a 0.3750-inch straight cylindrical shank. Compatible with cast iron, hardened steel, non-ferrous metal, and general steel workpieces as identified by the manufacturer for this series.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trades professionals familiar with carbide tooling. Secure the straight shank firmly in a properly sized chuck or collet before operation, and verify spindle speed and feed rate are appropriate for carbide tooling in the target material. Carbide is brittle and more susceptible to chipping from side loads or interrupted cuts than high-speed steel; avoid lateral pressure during drilling. Inspect the cutting edges before each use and replace the bit if chipping or wear is observed.
