Guhring 9005300017800 Jobber Drill Size 50 Firex

Product Description

The GUHRING 9005300017800 is a powdered metal jobber drill designed for precision drilling in cast iron and steel. Built to DIN 338 standards, it features a 130-degree cone relief point and a parabolic flute geometry that promotes fast chip evacuation and reduces heat buildup. The FIREX coating extends tool life by increasing surface hardness and reducing friction during cutting. At 1.81 inches overall length with a 0.87-inch flute length, this is a compact, high-performance drill suited for tight-clearance work. Licensed HVAC techs, machinists, and industrial service professionals working with metal substrates will find this drill reliable for repeat-use applications.

This drill is intended for right-hand cutting in cast iron and steel workpieces, making it a practical choice for production drilling, maintenance repair, and fabrication environments. The straight-cylindrical shank fits standard drill chucks without adapters. The parabolic flute with fast spiral type and web-thinned point reduces entry force and improves hole quality in ferrous materials. It does not support coolant-through delivery, so external coolant or cutting fluid should be applied when drilling at depth.

Key Features

• 130-degree cone relief point optimized for cast iron and steel drilling
• Powdered metal construction delivers improved hardness and wear resistance over standard HSS
• FIREX coating reduces friction and extends tool life in ferrous materials
• Parabolic flute with fast spiral promotes efficient chip removal and reduces heat at the cutting edge
• Web-thinned point lowers thrust requirements and improves centering
• Straight-cylindrical shank fits standard chucks with no adapter required

Compatibility

Designed as an OEM-style replacement or direct-use drill for standard straight-chuck drill presses, CNC machining centers, and handheld drill drivers accepting straight-cylindrical shanks in the applicable diameter range.

Installation Notes

This drill is installed and operated by machinists, maintenance technicians, and trade professionals working with metal fabrication or repair. Secure the shank fully in the chuck and verify runout before drilling. Apply external cutting fluid when drilling to depth to manage heat, since this tool does not support coolant-through delivery. Follow applicable shop safety practices, including eye protection and secure workpiece fixturing, before operating.
