Guhring 9002050017800 No. 50 Hss Jobber Drill Bit

Product Description

The GUHRING 9002050017800 is a jobber-length twist drill bit sized to wire gauge No. 50 (0.0701 inches decimal equivalent) and built from M2 high speed steel with a bright, uncoated finish. It features a standard 118-degree split point with web thinning for cleaner entry and reduced thrust on start-up. The two-flute spiral design uses a regular helix and tapered web configuration to evacuate chips efficiently during through-hole and blind-hole drilling. Manufactured to DIN 338 standards, this bit is suited for general-purpose drilling in production and maintenance environments where consistent hole tolerances are required.

This drill bit is intended for use in cast iron and steel workpieces, covering primary material grades K and P per DIN classification. The straight-cylindrical shank seats directly in standard drill chucks and collet holders without adaptation. Typical install scenarios include bench drill presses, CNC machining centers, hand drills, and drill-tap stations where small-diameter precision holes are needed. It is a single-piece, individual-sale item sold in a minimum quantity of one.

Compatibility

Designed as a general-purpose jobber-length drill bit per DIN 338 Series 205 for use in any standard drill chuck or collet system accepting a 0.0701-inch (1.78 mm) straight-cylindrical shank.

Installation Notes

A licensed machinist or qualified technician should secure the shank fully within the chuck or collet before operation, verifying runout is within acceptable limits for the required hole tolerance. Disengage and de-energize the machine spindle completely before changing or inspecting bits. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, noting that this bit does not support through-coolant delivery. Follow shop safety practices and applicable OSHA machine-guarding requirements when operating drilling equipment.
