Guhring 9005300039700 5/32 Inch Jobber Drill Bit Firex Pm

Product Description

The GUHRING 9005300039700 is a jobber length drill bit designed for high-performance drilling in demanding metal-cutting applications. Built from PM-ASP-60 powdered metal (PM) and finished with a FIREX coating, it delivers extended tool life in abrasive and hard materials. The bit features a 130-degree cone relief point for accurate entry and reduced thrust, a parabolic flute geometry for efficient chip evacuation, and a web-thinned, tapered web configuration that lowers cutting resistance at the tip. With an overall length of 2-15/16 inches and a 5/32-inch straight-cylindrical shank, this bit conforms to DIN 338 standards. Licensed HVAC technicians, machinists, pipefitters, and general trade professionals use this bit where standard HSS tooling falls short.

This drill bit is suited for right-hand cutting in cast iron and steel workpieces, making it a practical choice for fabrication shops, mechanical contractors, and field service technicians who regularly drill through structural steel, pipe fittings, and cast components. The parabolic flute design supports a flute-to-diameter ratio of 5xD, allowing deeper chip clearance without packing. It is sold individually and is appropriate for use in standard drill presses, hand drills, and CNC drilling operations where a 5/32-inch diameter hole is required.

Key Features

• PM-ASP-60 powdered metal construction for increased hardness and wear resistance over standard HSS
• FIREX coating reduces friction and extends tool life in ferrous materials
• 130-degree cone relief point angle improves self-centering and reduces walking on hard surfaces
• Parabolic flute geometry at a 5xD ratio promotes fast, clean chip evacuation
• Web-thinned tapered web lowers cutting force and reduces heat buildup at the tip
• Conforms to DIN 338 specification for consistent dimensional tolerances

Compatibility

Designed for drilling cast iron and steel workpieces per primary workpiece material codes K and P. Conforms to DIN 338 standards and fits any drill chuck accepting a 5/32-inch straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with metal-cutting operations. Secure the workpiece firmly before drilling and ensure the drill chuck is properly tightened to prevent slippage. Do not exceed the maximum drilling depth of 1.459 inches without retracting to clear chips. Use appropriate cutting fluid or coolant when drilling steel to manage heat, even though this bit does not have through-coolant capability.
