Guhring 9005300044000 Jobber Drill Bit 0.1732in Firex Pm

Product Description

The GUHRING 9005300044000 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 coated with FIREX for extended tool life, this bit features a 130-degree cone relief point and a parabolic flute geometry that promotes efficient chip evacuation at depth. The straight-cylindrical shank measures 0.1732 inches in diameter, matching the cutting diameter for easy chuck engagement. With an overall length of 3-5/32 inches and a flute length of 1-27/32 inches, it fits standard jobber-length applications. Licensed HVAC, plumbing, and general mechanical tradespeople who drill ferrous metals will find this bit well-suited to production and maintenance work.

This drill bit is rated for use in cast iron and steel workpiece materials, classified under material codes K and P. It conforms to DIN 338, the standard governing jobber-length twist drills. The Series 530 designation places it in Guhring's high-performance PM line, making it appropriate for both hand-held drilling operations and drill press or CNC machine applications where consistent hole quality in ferrous metals is required. The parabolic flute with a 5xD flute-to-diameter ratio helps clear chips in deeper holes without packing.

Key Features

• PM-ASP-60 powdered metal construction for improved hardness and wear resistance over standard HSS
• FIREX coating reduces friction and extends cutting life in ferrous materials
• 130-degree cone relief point with web thinning for reduced thrust and easier entry into cast iron and steel
• Parabolic flute profile with 5xD ratio promotes chip flow and reduces clogging at depth
• Right-hand cut with straight-cylindrical shank for compatibility with standard drill chucks
• Conforms to DIN 338 specification for jobber-length twist drills

Compatibility

Designed for drilling cast iron and steel workpieces. Fits any standard drill chuck accepting a 0.1732-inch straight-cylindrical shank. Conforms to DIN 338 jobber-length standards.

Installation Notes

This bit is installed and used by machinists, millwrights, and trade professionals working with ferrous metals. Secure the shank fully in the chuck before operation and verify chuck key is removed before starting the machine. No coolant-through capability is present on this bit; apply cutting fluid externally when drilling steel to manage heat. Inspect the cutting edges before each use and replace when wear causes increased thrust or poor hole finish.
