Guhring 9003050015100 Cobalt Jobber Drill Bit No. 53

Product Description

The GUHRING 9003050015100 is a cobalt jobber length drill bit sized to wire gauge No. 53, equivalent to 0.0595 inches in decimal diameter. Built to DIN 338 standards, it features a 118-degree standard point angle, a two-flute regular spiral configuration, and a web-thinned, tapered web for improved chip evacuation and reduced thrust at entry. The bright uncoated finish suits general-purpose drilling applications across a range of metals. Overall length is 43 millimeters, with a straight-cylindrical shank measuring 0.0594 inches in diameter. This bit is well suited to production environments and maintenance shops where precise small-diameter drilling is required.

Rated for use in cast iron and steel workpieces under primary material codes K and P, the 9003050015100 is a general-purpose tool appropriate for light machining, metalworking, and mechanical service applications. The right-hand cutting direction and regular spiral flute geometry make it compatible with standard drill presses, CNC machining centers, and handheld corded drills. The flute-to-diameter ratio is 5xD, and maximum drilling depth reaches 0.698 inches (17.74 millimeters). Coolant-through capability is not provided. Sold individually, it fits operations that require single-piece procurement for small-lot or prototype work.

Key Features

• Wire gauge No. 53 size — 0.0595 inch decimal diameter for precise small-bore drilling
• Cobalt construction for improved heat and wear resistance compared to standard high-speed steel
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• Two-flute regular spiral geometry promotes controlled chip removal in ferrous materials
• Meets DIN 338 specification for jobber length geometry and dimensional tolerances
• Straight-cylindrical shank compatible with standard drill chucks and collets

Compatibility

Designed as a general-purpose jobber length drill bit for use in cast iron and steel workpieces. Suitable for standard drill chucks accepting a straight-cylindrical shank of approximately 0.0594 inches in diameter.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with small-diameter tooling. Before mounting, confirm the drill chuck or collet is clean, undamaged, and rated for the shank diameter. Secure the workpiece firmly to prevent deflection or bit breakage at this small diameter. Observe appropriate spindle speeds for cobalt tooling in ferrous materials and follow shop safety practices for rotating equipment.
