Guhring 9005300012000 Jobber Drill Bit 0.0472 in Firex Pm

Product Description

The GUHRING 9005300012000 is a jobber length drill bit designed for high-performance drilling in ferrous materials. Built from PM-ASP-60 powdered metal (PM), it delivers the hardness and edge retention required for demanding production and maintenance applications. The bit carries a FIREX coating for added surface hardness and heat resistance. At 0.0472 inches in diameter with a 1.5-inch overall length, this is a small-diameter tool intended for precision hole work. The 130-degree point angle and parabolic flute geometry promote efficient chip evacuation and help reduce thrust force during entry. Web thinning further reduces the chisel edge load at the point.

This drill bit is suited for drilling cast iron and steel in both shop and field environments. The parabolic flute profile and web-thinned, cone-relief point make it appropriate for higher feed rates in production environments where tool life and hole quality matter. The straight-cylindrical shank fits standard keyless and keyed chucks. It is typically used by machinists, maintenance technicians, and metalworking tradespeople working with tight-tolerance small-diameter holes in steel and cast iron workpieces.

Key Features

• PM-ASP-60 powdered metal construction for superior hardness and wear resistance over standard HSS
• FIREX coating adds heat and oxidation resistance for extended tool life in ferrous materials
• 130-degree point angle with cone-relief geometry reduces walking and improves entry accuracy
• Parabolic flute profile promotes fast chip evacuation and allows higher feed rates
• Web-thinned, tapered web design reduces thrust at the cutting point
• Right-hand cut with straight-cylindrical shank for compatibility with standard drill chucks
• Meets DIN 338 specification

Compatibility

Designed for drilling cast iron and steel workpieces. Suitable for use in any standard drill press, CNC machining center, or handheld drill accepting a 0.0472-inch straight-cylindrical shank. Primary workpiece material codes K and P per ISO classification.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tradespeople familiar with small-diameter tooling. Secure the shank fully in the chuck and verify runout before drilling to prevent bit breakage at this diameter. Coolant-through is not supported on this tool; use external cutting fluid appropriate for cast iron or steel when operating at higher speeds. Follow applicable workplace safety standards and machine manufacturer guidelines for RPM and feed rate selection.
