Guhring 9005300011800 Jobber Drill Bit 0.0465in Firex

Product Description

The GUHRING 9005300011800 is a jobber length twist drill bit engineered for high-performance drilling in cast iron and steel. Built from powdered metal and coated with FIREX for heat and wear resistance, this bit features a 130-degree cone relief point for clean entry and reduced walking. The parabolic flute geometry promotes fast chip evacuation, making it well suited for production environments where tool life and hole quality matter. The straight-cylindrical shank is compatible with standard drill chucks. At 1.42 inches overall length with a 0.55-inch flute length, this is a compact, precision-ground tool conforming to DIN 338 standards.

This drill bit is designed for right-hand cutting in cast iron and steel workpieces. The parabolic fast-spiral flute and web-thinned point reduce thrust requirements, which is especially useful when drilling small-diameter holes in harder ferrous materials. It carries a wire gauge designation of number 56, corresponding to 0.0465 inches in decimal inch sizing. Typical applications include precision hole-making in fabrication shops, maintenance facilities, and manufacturing environments where consistent performance in a small-diameter bit is required. Maximum drilling depth is 0.481 inches.

Key Features

• FIREX coating improves heat resistance and extends tool life in ferrous materials
• 130-degree cone relief point reduces thrust and minimizes drill walking on entry
• Parabolic fast-spiral flute design promotes efficient chip evacuation
• Web-thinned construction lowers cutting force requirements
• Diameter tolerance h8 ensures consistent, repeatable hole sizing
• Conforms to DIN 338 standard for jobber length drill geometry

Compatibility

Designed as an OEM-style precision drill bit for use in standard keyed or keyless drill chucks accepting a straight-cylindrical shank. Rated for primary workpiece materials cast iron and steel per material codes K and P.

Installation Notes

This bit is installed by machinists and toolroom technicians using drill presses, CNC machining centers, or hand drills equipped with compatible chucks. Before mounting, verify the chuck capacity accommodates a 1.18-millimeter shank diameter. Secure the shank fully in the chuck and confirm runout is within acceptable limits before beginning a cut. Coolant-through is not supported on this tool; use external cutting fluid or appropriate lubrication for the workpiece material when required.
