Guhring 9005300026000 Jobber Drill Bit 0.1024 in Pm

Product Description

The GUHRING 9005300026000 is a jobber-length drill bit engineered for high-performance drilling in ferrous materials. Built from PM-ASP-60 powdered metal (high-speed steel powder metallurgy), it carries a FIREX coating that extends tool life in demanding production environments. The bit measures 0.1024 inches in diameter with a 2.25-inch overall length and features a 130-degree split-point geometry for reduced thrust and self-centering entry. A parabolic flute design improves chip evacuation, making it well suited for deeper holes relative to diameter. Licensed machinists, tool-and-die setups, and HVAC fabrication shops reach for this bit when working through cast iron or steel at sustained duty cycles.

This drill bit is rated for use on cast iron and steel workpieces, matching primary material codes K and P per DIN classification. The parabolic flute provides a 5xD flute-to-diameter ratio, supporting a maximum drilling depth of 1.028 inches (26.10 mm) without through-coolant. The straight cylindrical shank seats directly in standard drill chucks and collet holders without adapters. It conforms to DIN 338 geometry standards and is sold individually, making it a practical choice for replacing a single worn bit in a set or stocking a specific size for a recurring application.

Key Features

• PM-ASP-60 powdered metal construction for improved wear resistance over standard HSS
• FIREX coating reduces friction and extends tool life in steel and cast iron
• 130-degree cone-relief point with web thinning for lower entry thrust and accurate starts
• Parabolic flute profile with tapered web configuration aids chip flow in deeper cuts
• Right-hand cut, straight cylindrical shank fits standard chucks and collets without modification
• Conforms to DIN 338 standard geometry for consistent dimensional performance

Compatibility

Designed for drilling cast iron and steel workpieces (DIN material codes K and P). Fits any standard drill chuck or collet holder accepting a 0.1024-inch straight cylindrical shank. Conforms to DIN 338 jobber-length specifications.

Installation Notes

Install and remove drill bits only with the machine fully stopped and power locked out. Seat the shank fully in the chuck or collet and confirm runout before engaging the workpiece. Use appropriate cutting fluid or mist for extended runs in steel to maintain coating integrity and edge life. Inspect the cutting edge and web condition before each use; a worn or chipped point should be reground or replaced before continuing production.
