Guhring 9005300095200 Jobber Drill Bit 3/8 in Pm Firex

Product Description

The GUHRING 9005300095200 is a jobber-length drill bit designed for high-performance drilling in cast iron and steel. Built from PM-ASP-60 powdered metal and finished with a FIREX coating, it handles demanding production environments where standard HSS tooling falls short. The bit features a 130-degree point angle with cone relief geometry and a parabolic flute design that improves chip evacuation and reduces heat buildup. Overall length is 125 millimeters with a flute length of 81 millimeters and a straight-cylindrical shank. It is sold individually and suited for use in CNC machining centers, drill presses, and manual production setups where consistent hole quality is required.

This drill bit is rated for primary workpiece materials including cast iron and steel, corresponding to material codes K and P. It fits standard 3/8-inch drill chucks with a matching shank diameter. The parabolic flute and web-thinned, tapered web construction reduce thrust requirements and make the bit practical for through-hole and blind-hole applications. Maximum drilling depth is 2.863 inches (72.72 millimeters), and the 5xD flute-to-diameter ratio supports deeper passes without regrinding. The Series 530 designation aligns with DIN 338 specification standards for jobber-length drills.

Key Features

• PM-ASP-60 powdered metal construction for improved wear resistance over standard HSS
• FIREX coating reduces friction and extends tool life in ferrous materials
• 130-degree cone relief point angle optimized for cast iron and steel entry
• Parabolic flute profile improves chip flow and reduces heat at the cutting edge
• Web-thinned, tapered web lowers thrust and improves centering
• Conforms to DIN 338 jobber-length standard for dimensional consistency

Compatibility

Designed for use in 3/8-inch drill chucks on CNC machining centers, drill presses, and hand-held power tools. Primary workpiece materials are cast iron and steel (material codes K and P per DIN classification).

Installation Notes

Installation and use should be performed by a qualified machinist or tool operator. Secure the shank fully in the chuck before operation and confirm runout is within acceptable limits for the application. Do not exceed the recommended drilling depth of 2.863 inches without retracting to clear chips. Use appropriate cutting fluid or coolant where workpiece material and machine setup permit, even though this bit does not have through-coolant capability.
