Guhring 9002050031300 Jobber Drill 3.13mm Hss Oxide

Product Description

The GUHRING 9002050031300 is a high speed steel jobber-length twist drill bit designed for general-purpose hole-making in metalworking applications. Built to DIN 338 standards, this bit features a 118-degree standard point angle with web thinning for improved centering and reduced thrust at entry. The oxide coating provides basic lubricity and corrosion resistance during cutting operations. At 3.13 mm in diameter with a straight-cylindrical shank of matching 3.13 mm diameter, the bit fits standard drill chucks without adapters. It is suited for machinists, tool and die shops, maintenance technicians, and fabricators working in production or field environments.

This drill bit is rated for primary use in cast iron and steel workpieces, making it a practical selection for ferrous metal drilling tasks across light manufacturing, MRO, and general fabrication. The regular spiral flute geometry and 2-flute configuration provide consistent chip evacuation in these materials. The overall length of 65 mm and flute length of 36 mm are consistent with standard jobber-length proportions, allowing use in drill presses, CNC machining centers, and handheld power drills with appropriate chuck capacity.

Key Features

• DIN 338 standard jobber-length geometry with 118-degree standard point angle
• M2 high speed steel construction with oxide coating for basic wear and corrosion resistance
• Web-thinned tapered web design reduces entry thrust and improves point stability
• Straight-cylindrical shank fits standard 3-jaw chucks and collet systems
• Right-hand cutting with regular spiral flute for reliable chip evacuation in ferrous materials
• Maximum drilling depth of 31.31 mm (approximately 1.233 inches) within the flute length

Compatibility

Designed as a general-purpose OEM-style jobber drill suitable for use in standard drill presses, CNC drilling machines, and handheld power drills that accept a 3.13 mm straight-cylindrical shank. Rated for cast iron and steel workpiece materials per manufacturer specifications.

Installation Notes

Installation and use should be performed by qualified machinists or experienced tradespeople familiar with rotating cutting tools. Always secure the workpiece firmly before drilling and ensure the chuck is fully tightened on the shank before operation. Follow appropriate cutting speed and feed rate tables for M2 HSS drills in the target material to avoid premature tool wear or breakage. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
