Guhring 9002050013700 Jobber Drill Bit 1.37mm Hss

Product Description

The GUHRING 9002050013700 is a jobber length drill bit designed for general-purpose drilling in metalworking applications. Built from M2 high speed steel with a bright uncoated finish, it delivers consistent performance across a range of common workpiece materials. The bit measures 1.37 mm in diameter with an overall length of 40 mm and a flute length of 18 mm. The 118-degree standard point angle and web-thinned geometry reduce entry force and improve chip clearance, making this bit well suited for production and maintenance drilling tasks performed by machinists and maintenance technicians.

This drill bit is intended for drilling cast iron and steel in both shop and field environments. The DIN 338 standard governs its dimensional tolerances, with a diameter tolerance of +0.000 to -0.014 mm, ensuring consistent fit in standard drill chucks. The straight-cylindrical shank and regular spiral flute geometry make it compatible with conventional hand drills, drill presses, and CNC machining centers. It is sold individually but requires a minimum order quantity of 10 units per order.

Key Features

• M2 high speed steel construction for durability in steel and cast iron drilling
• 118-degree standard point angle with web-thinned tip for reduced thrust and clean entry
• Bright uncoated finish suitable for general-purpose applications
• Right-hand cut, regular spiral flute with tapered web configuration for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks without adaptation
• Conforms to DIN 338 dimensional specification for consistent interchangeability

Compatibility

Designed as a general-purpose jobber length drill bit per DIN 338, compatible with standard drill chucks accepting a 1.37 mm straight-cylindrical shank. Rated for primary use in cast iron and steel workpieces.

Installation Notes

This bit is installed and used by machinists, maintenance technicians, and tool and die professionals. Secure the shank fully in the drill chuck and verify concentricity before use. Apply appropriate cutting fluid when drilling steel to extend tool life and maintain hole quality. Inspect the cutting edges for wear or chipping before each use and replace bits that show signs of degradation to avoid workpiece damage.
