Guhring 9005300016100 Jobber Drill Bit 52 Firex Pm

Product Description

The GUHRING 9005300016100 is a jobber length drill bit sized to wire gauge 52 (0.0634 inches decimal) and designed for high-performance drilling in ferrous materials. Built from powdered metal (PM) with a FIREX coating, this bit delivers extended tool life in demanding production environments. The 130-degree split point with cone relief geometry reduces thrust and improves self-centering on entry. A parabolic flute with fast spiral design accelerates chip evacuation, reducing heat buildup and the risk of re-cutting chips. Overall length is 1.69 inches with a 0.79-inch flute length, making it well-suited for precision drilling in tight clearances where a standard jobber geometry is required.

This drill bit is rated for primary use in cast iron and steel workpieces, covering material codes K and P in cutting material classifications. The straight-cylindrical shank (1.61 mm diameter) fits standard drill chucks without a reducer. The web-thinned point reduces feed force requirements, which is particularly useful in high-cycle CNC or manual drilling applications where consistent hole quality matters. It conforms to DIN 338 standards and carries a Series 530 designation within the GUHRING product line. Maximum drilling depth is 0.693 inches (17.59 mm). Sold individually with a minimum order quantity of 10 units.

Key Features

• Wire gauge 52 size — 0.0634 inches decimal diameter with h8 tolerance
• FIREX coating extends tool life in cast iron and steel applications
• 130-degree cone relief point with web thinning reduces entry thrust
• Parabolic fast-spiral flute at 5xD flute-to-diameter ratio promotes chip clearing
• Straight-cylindrical shank compatible with standard drill chucks
• Conforms to DIN 338 specification for jobber length geometry

Compatibility

Designed as an OEM-specification replacement or production-use drill bit for applications requiring a wire gauge 52 jobber length drill in cast iron and steel — material codes K and P — per DIN 338 Series 530 standards. No coolant-through capability; use with external coolant or dry cutting as appropriate for the application.

Installation Notes

Install in a drill chuck or collet sized to accept a 1.61 mm straight-cylindrical shank, verifying chuck runout before high-precision use. Confirm the workpiece is properly fixtured and the machine spindle is at the correct RPM and feed rate for the material being drilled before engaging the cut. Do not use this bit in applications requiring coolant-through delivery, as this tool does not support internal coolant passages. Disposal and handling of PM tool steel chips should follow applicable shop safety procedures.
