Guhring 9005300057900 Jobber Drill Bit No.1 Firex Pm

Product Description

The GUHRING 9005300057900 is a jobber length drill bit designed for high-performance drilling in steel and cast iron. Built from powdered metal and finished with a FIREX coating, it delivers extended tool life in demanding production environments. The bit measures 0.2280 inches in diameter (No. 1 wire size) with a 130-degree point angle and parabolic flute geometry that promotes fast chip evacuation and reduces heat buildup. Overall length is 3.66 inches. This bit is suited for use by machinists, maintenance technicians, and fabricators working with ferrous materials in shop or field settings.

This drill bit is well suited for production and job-shop drilling operations in steel and cast iron workpieces. The Series 530 design with a straight-cylindrical shank fits standard drill chucks without adapters. The parabolic flute with a 5xD flute-to-diameter ratio supports deeper hole applications while maintaining chip flow. Maximum drilling depth is 1.902 inches. The right-hand cut and web-thinned point reduce entry force and improve centering accuracy on flat or slightly curved surfaces.

Key Features

• FIREX coating for improved wear resistance and heat dissipation in ferrous materials
• Powdered metal construction provides higher hardness and toughness compared to standard HSS
• 130-degree point angle with cone relief tip reduces thrust and improves hole entry
• Parabolic flute geometry with fast spiral promotes efficient chip evacuation
• Web-thinned design lowers cutting resistance at the drill point
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Conforms to DIN 338 standard for jobber length drill bits

Compatibility

Designed as an OEM-style jobber length drill bit for use in standard drill chucks and collet systems accepting a straight-cylindrical shank. Primary workpiece materials are steel (material code P) and cast iron (material code K) per ISO classification.

Installation Notes

Install and remove this bit only with the drill motor fully de-energized and the chuck or collet completely secured before operation. Machinists should verify chuck runout and shank seating before initiating a cut to prevent bit wander or premature wear. Coolant-through is not supported on this bit, so adequate flood or mist cooling at the cutting zone is recommended when drilling deep holes or high-cycle production runs. Follow applicable shop safety standards for rotating tooling when operating.
