Guhring 9005150042200 Screw Machine Drill Bit Size 19

Product Description

The GUHRING 9005150042200 is a screw machine length (stub) drill bit designed for high-productivity drilling in steel and cast iron. Built from powdered metal and coated with GUHRING nano-FIREX multi-layer coating, it delivers extended tool life in demanding production environments. The 130-degree point angle with cone relief and web-thinned geometry reduces thrust and improves chip evacuation. At 2.1654 inches overall length with a parabolic fast-spiral flute, this bit is engineered for short-hole applications where rigidity and penetration speed matter. Licensed tradespeople and production machinists working in job shops, MRO, or light manufacturing are the primary users.

This drill bit suits applications requiring precise, clean holes in steel and cast iron workpieces. The stub length format provides added rigidity compared to jobber-length bits, making it well suited for screw machine work, CNC drilling operations, and fixture-based setups. The straight cylindrical shank fits standard drill chucks and collet holders without modification. The parabolic flute profile promotes efficient chip removal, particularly in blind-hole drilling up to 0.6170 inches deep.

Key Features

• nano-FIREX multi-layer coating for extended tool life in ferrous materials
• 130-degree point angle with cone relief and web thinning for reduced entry force
• Parabolic fast-spiral flute for efficient chip evacuation in blind holes
• Stub length construction increases rigidity over standard jobber bits
• Straight cylindrical shank with h8 diameter tolerance for precise chuck fit
• Conforms to DIN 1897 specification

Compatibility

Designed as a DIN 1897 Series 515 stub drill for use in steel and cast iron workpieces. Fits any standard drill chuck or collet accepting a 0.1661-inch (4.22 mm) straight shank. No specific OEM equipment compatibility is stated in the product data.

Installation Notes

Machinist or CNC operator installation. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Secure the shank fully in the chuck or collet to the recommended engagement depth for the holder being used. Follow shop-standard speeds and feeds for powdered metal tooling in ferrous materials; do not exceed the 0.6170-inch maximum drilling depth for this bit geometry.
