Guhring 9005020130000 Extra Length Hss Drill Bit 0.5118 in

Product Description

The GUHRING 9005020130000 is a high speed steel extra length drill bit engineered for deep hole drilling applications in metalworking and machining environments. It carries a 0.5118 inch diameter, a 130-degree drill point angle, and a parabolic flute geometry that promotes efficient chip evacuation in deep-bore operations. The overall length of 11.614 inches (295 mm) and a maximum drilling depth of 7.303 inches give this bit the reach needed for through-hole and deep pocket work that standard length drills cannot achieve. It ships uncoated and right-hand cutting, conforming to DIN 1869 specification. Machinists and tool-and-die professionals are the primary installers of this bit.

This bit is built for high-performance deep hole drilling, with a flute-to-diameter ratio of 15xD that supports extended reach without sacrificing rigidity. The primary workpiece material is aluminum, with material codes K, N, and P indicating suitability for non-ferrous metals, non-metals, and steel-grade materials respectively. Its web-thinned, tapered web configuration reduces thrust force at the cutting tip, making it well suited for CNC machining centers, drill presses, and manual lathes where deep hole accuracy is critical. The straight-cylindrical shank provides straightforward clamping in standard drill chucks and collets.

Key Features

• Parabolic flute design promotes aggressive chip evacuation in deep hole operations
• Web-thinned tapered web reduces cutting thrust and entry force
• 130-degree drill point angle suited for aluminum and non-ferrous workpiece materials
• DIN 1869 compliant construction for consistent dimensional standards
• Straight-cylindrical shank at 0.5118 inches for standard chuck and collet compatibility
• Right-hand cutting direction, 2-flute configuration

Compatibility

Designed as a DIN 1869 Series 502 extra length drill bit for use in CNC machining centers, drill presses, and lathes requiring deep hole capability in aluminum and compatible non-ferrous or steel-grade materials.

Installation Notes

Installation of this drill bit is performed by machinists or tooling technicians in a machine shop environment. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the straight-cylindrical shank firmly in a properly sized drill chuck or collet to the equipment manufacturer's specified clamping torque. Verify the selected RPM and feed rate are appropriate for the workpiece material and bit diameter before initiating the cut.
