Sgs 53002 Solid Carbide Jobber Drill Bit 0.2210 in

Product Description

The SGS 53002 is a solid carbide jobber-length drill bit designed for precision hole-making in demanding metalworking applications. Built to Series 103 specifications and conforming to DIN 6539, it features a 150-degree split point, three-flute regular spiral geometry, and a bright uncoated finish. The bit measures 0.2210 inches in diameter (Wire Size 2, 5.61 mm) with a 3.0-inch overall length and a 1.75-inch flute length. Micrograin carbide construction provides the hardness and wear resistance needed when drilling cast iron, hardened steel, carbon steel, and non-ferrous metals. A web-thinned, tapered web design reduces thrust force at entry and improves chip evacuation on deep holes.

This drill bit is suited for production machining and maintenance environments where accuracy and tool life are critical. The straight cylindrical shank seats directly in standard drill chucks and collet holders without modification. Typical applications include precision drilling in CNC machining centers, drill presses, and manual mills working with ferrous and non-ferrous stock. The 150-degree point angle is optimized for hard and abrasive materials, reducing the tendency to walk on entry. It is used by machinists, tool-and-die makers, and maintenance technicians in industrial, manufacturing, and fabrication settings.

Key Features

• Solid micrograin carbide construction for extended tool life in hard and abrasive materials
• 150-degree point angle reduces entry deflection in cast iron, hardened steel, and non-ferrous metals
• Three-flute spiral geometry improves chip clearance and surface finish in through-hole drilling
• Web-thinned tapered web lowers thrust requirements and supports deeper hole entry
• Bright uncoated finish compatible with a wide range of cutting fluids and dry-drilling setups
• Diameter tolerance held to +0.0000 to -0.0005 inches for close-tolerance hole sizing

Compatibility

Designed as a general-purpose replacement or production drill bit for applications requiring Wire Size 2 (0.2210 inches) drilling in cast iron, hardened steel, non-ferrous metal, and carbon steel. Fits standard straight-shank drill chucks and collet systems accepting a 0.2210-inch shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with cutting tool safety. Ensure the machine spindle is fully stopped and locked out before changing or securing the bit in the chuck or collet. Use appropriate cutting fluid or coolant for the workpiece material to maximize tool life, noting this bit does not support through-coolant delivery. Inspect the cutting edges for chipping or wear before each use, as carbide tools can fracture if run at incorrect speeds or feeds for the material.
