Guhring 9005300075400 Jobber Drill Bit 19/64 in

Product Description

The GUHRING 9005300075400 is a jobber length drill bit engineered for high-performance drilling in cast iron and steel. Built from PM-ASP-60 powdered metal (high-speed steel processed via powder metallurgy), this bit delivers consistent hardness and wear resistance across the full cutting edge. It carries a FIREX coating that reduces friction and extends tool life in demanding production environments. The 130-degree point angle with cone relief geometry and web-thinned, tapered web configuration improves chip evacuation and reduces thrust force at entry. With a parabolic flute design and a 5xD flute-by-diameter ratio, it handles deeper hole applications without excessive chip packing. Licensed HVAC, mechanical, and fabrication tradespeople will find this bit suited to precision drilling tasks on ferrous materials.

This drill bit is sized at 19/64 inches (0.2969 inches decimal equivalent) with a straight-cylindrical shank of matching 19/64-inch diameter. The overall length is 109 millimeters, the flute length is 69 millimeters, and the shank length is 42 millimeters. Maximum drilling depth reaches 63.69 millimeters (2.507 inches). It carries a right-hand cut direction and a two-flute configuration. The Series 530 designation aligns with DIN 338 standards, making it a recognized specification in industrial and trade-shop environments. Coolant-through capability is not included in this configuration.

Key Features

• PM-ASP-60 powdered metal construction for consistent hardness and wear resistance in ferrous materials
• FIREX coating reduces friction and extends cutting life in cast iron and steel applications
• 130-degree cone relief point with web-thinned, tapered web for reduced thrust and cleaner entry
• Parabolic flute geometry with 5xD ratio promotes chip evacuation in deeper holes
• Straight-cylindrical shank for secure chuck retention across standard drill chucks
• Conforms to DIN 338 specification for consistent dimensional tolerance (-0.022 to 0.000 mm diameter)

Compatibility

Designed for drilling cast iron and steel workpieces (material codes K and P). Suitable for use in standard drill chucks accepting a 19/64-inch straight-cylindrical shank. Conforms to DIN 338 specification for jobber length drill bits.

Installation Notes

This bit is installed by machinists, fabricators, and trade professionals using standard keyed or keyless drill chucks rated for the shank diameter. Ensure the chuck is fully tightened and the workpiece is secured before initiating the cut. Do not exceed the rated maximum drilling depth of 63.69 millimeters in a single pass without clearing chips. For extended tool life, use appropriate cutting fluid when drilling steel.
