Guhring 9006690039700 Cobalt Taper Drill 5/32 in

Product Description

The GUHRING 9006690039700 is a taper length cobalt drill bit engineered for demanding production drilling applications. Built from M-35 cobalt high-speed steel, it delivers superior heat and wear resistance compared to standard HSS tooling. The bit measures 0.1562 inches (5/32 inch) in diameter with a 130-degree split point that promotes self-centering entry and reduces walking on entry without a center punch. Overall length is 4.685 inches with a flute length of 3.0709 inches, giving this bit extended reach for deeper holes in the taper-length category. It is right-hand cut with a regular spiral flute and a tapered web configuration, conforming to DIN 340. Licensed machinists, tool-and-die makers, and maintenance technicians install this bit in standard drill presses, CNC machines, and hand drills with compatible chucks.

This bit suits ferrous and non-ferrous metals, stainless steel, and other tough materials where M-35 cobalt construction provides an edge over standard HSS. The Series 669 taper length configuration is a common choice in production shops where deep hole clearance is needed without stepping up to a fully extended aircraft-length bit. The 10xD flute-to-diameter ratio supports chip evacuation in deeper passes. Web thinning reduces thrust load at the cutting tip, making it practical for manual drilling operations as well as CNC-driven cycles.

Key Features

• M-35 cobalt material grade for enhanced heat resistance and tool life in hard materials
• 130-degree split point with self-centering geometry reduces drill walk on entry
• Web-thinned tapered web lowers thrust requirements and improves cutting efficiency
• 3.0709-inch flute length provides extended reach per DIN 340 taper length standard
• Right-hand spiral flute promotes consistent chip evacuation during drilling
• Cylindrical shank compatible with standard 3-jaw chucks and collet systems

Compatibility

Designed as an OEM-style replacement or direct-use taper length drill bit for standard cylindrical-shank drill chucks accepting a 5/32-inch (0.1562-inch) diameter tool, conforming to DIN 340 specifications.

Installation Notes

Installation and use should be performed by qualified machinists or tradespeople familiar with cutting tool selection and machine operation. Secure the workpiece and ensure the drill chuck is properly tightened before operation. Always power down and de-energize the machine before changing tooling. Follow applicable shop safety standards and manufacturer feed-and-speed recommendations for the specific workpiece material when setting up drilling parameters.
