Guhring 9005300019800 Jobber Drill Bit 5/64 in Firex Pm

Product Description

The GUHRING 9005300019800 is a jobber length drill bit designed for high-performance drilling in ferrous materials. Built from PM-ASP-60 powdered metal and finished with a FIREX coating, this bit delivers extended tool life in demanding production environments. It features a 130-degree cone relief point, a parabolic flute geometry, and a web-thinned tapered web for reduced thrust and improved chip evacuation. The overall length is 46 mm (approximately 1.81 inches), with a flute length of 22 mm (approximately 0.87 inches) and a straight-cylindrical shank. At 0.03 pounds, this is a precision tool sold individually and intended for use by machining professionals and maintenance trade technicians.

This drill bit is sized at 5/64 inch (0.0781 inch decimal) with a shank diameter of 5/64 inch, conforming to DIN 338 standards. It is rated for use in cast iron and steel workpieces, classified under material grade codes K and P. The parabolic flute design provides a 5xD flute-to-diameter ratio, supporting maximum drilling depths up to 0.828 inch (21.03 mm). Its FIREX coating reduces friction and heat buildup, making it well suited to repetitive drilling cycles in steel fabrication, mechanical maintenance, and light manufacturing applications.

Key Features

• PM-ASP-60 powdered metal construction for elevated hardness and wear resistance
• FIREX coating reduces friction and extends service life in ferrous materials
• 130-degree cone relief point angle optimized for steel and cast iron entry
• Parabolic flute geometry with 5xD ratio improves chip flow and reduces heat
• Web-thinned tapered web lowers drilling thrust and starting resistance
• Conforms to DIN 338 standard for consistent dimensional tolerances

Compatibility

Designed as a DIN 338 jobber length drill bit for use in cast iron and steel workpieces, classified under primary workpiece material codes K and P. Suited for standard drill chucks accepting a 5/64 inch straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or trade technicians familiar with drilling operations and machine tool safety. Secure the shank fully in a compatible drill chuck and verify concentricity before operation. Always power down and de-energize the machine before changing bits. Follow applicable shop safety standards and manufacturer speed-and-feed recommendations for the specific workpiece material.
