Guhring 9005300014000 Jobber Drill Bit Size 54 Firex Pm

Product Description

The GUHRING 9005300014000 is a jobber-length drill bit in wire gauge size 54, with a decimal diameter of 0.0551 inches. It is manufactured from PM-ASP-60 powdered metal and finished with a FIREX coating for extended tool life in demanding applications. The 130-degree split point with cone relief geometry reduces thrust and self-centers on entry without a pilot hole. With a parabolic flute design and web-thinned, tapered web configuration, this bit provides efficient chip evacuation in both steel and cast iron. It is sized for precision small-diameter work and is installed by machinists, tool-and-die professionals, and maintenance technicians in production and MRO environments.

This drill bit is suited for right-hand cutting operations in cast iron and steel workpieces, consistent with primary workpiece material codes K and P. The parabolic flute geometry with a 5xD flute-to-diameter ratio supports deeper chip clearance relative to standard jobber geometry. The straight-cylindrical shank measures 0.0551 inches in diameter and seats directly in standard chucks and collets. At an overall length of 1-9/16 inches with a maximum drilling depth of 0.626 inches, it fits compact drill presses, CNC machining centers, and handheld precision drills. The DIN 338 standard governs the dimensional specifications for this series.

Key Features

• FIREX coating provides heat and wear resistance for extended cutting life in ferrous materials
• PM-ASP-60 powdered metal construction offers higher hardness and edge retention compared to standard HSS
• 130-degree cone relief point with web thinning reduces entry thrust and improves self-centering
• Parabolic flute profile with 5xD ratio promotes efficient chip evacuation in deep-hole drilling
• DIN 338 conformance ensures dimensional interchangeability with standard jobber-length tooling
• Straight-cylindrical shank is compatible with standard drill chucks and collets

Compatibility

Designed as an OEM-style jobber-length drill bit conforming to DIN 338, suitable for use in standard drill chucks and collets accepting a 0.0551-inch straight-cylindrical shank across CNC and manual drilling equipment.

Installation Notes

This drill bit is installed by machinists and maintenance technicians using standard chuck or collet toolholding systems. Confirm chuck capacity and runout before seating the shank, and ensure the spindle is fully stopped before tool changes. Coolant-through is not supported on this bit; apply external cutting fluid appropriate for the workpiece material when drilling steel or cast iron. Follow applicable machine safety lockout procedures before any tooling adjustments.
