Guhring 9005300067500 Jobber Drill Bit 17/64 in Firex Pm

Product Description

The GUHRING 9005300067500 is a jobber length drill bit designed for high-performance drilling in cast iron and steel. Built from PM-ASP-60 powdered metal (PM) and finished with a FIREX coating, this bit delivers extended wear resistance and heat tolerance compared to standard high-speed steel tooling. It features a 130-degree point angle with cone relief geometry and a parabolic flute profile that promotes efficient chip evacuation. The straight-cylindrical shank and web-thinned, tapered web construction reduce entry force and improve centering. Licensed HVAC, mechanical, and general trade technicians as well as machinists installing metal components will find this bit suited to demanding production and service applications.

This drill bit is sized at 17/64 inch (0.2656 inch decimal) and conforms to DIN 338 standards. It is suited for drilling cast iron and steel workpieces in both shop and field environments. The Series 530 designation places it in a high-performance family intended for applications requiring tight tolerances and consistent hole quality across repeat cycles. It is sold individually and is appropriate wherever a reliable jobber-length drill is needed for metal fabrication, equipment installation, or structural work.

Key Features

• PM-ASP-60 powdered metal construction for elevated hardness and wear resistance
• FIREX coating reduces friction and extends tool life in ferrous materials
• 130-degree cone relief point angle improves self-centering on curved or hard surfaces
• Parabolic flute profile enhances chip flow and reduces heat buildup in deep holes
• Web-thinned tapered web lowers thrust requirements during drilling
• Conforms to DIN 338 standard for consistent dimensional accuracy

Compatibility

Designed as a DIN 338-compliant jobber length drill bit for use in standard drill chucks and collets accepting a 17/64 inch straight-cylindrical shank. Primary workpiece materials are cast iron and steel.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with metal drilling operations. Secure the workpiece firmly before drilling and verify chuck grip on the straight shank before applying feed pressure. Use appropriate cutting fluid or lubrication when drilling steel to manage heat; this bit does not feature coolant-through capability. Inspect the cutting edge before each use and replace if chipping or dulling is observed.
