Guhring 9005350059500 Taper Length Drill Bit 15/64in

Product Description

The GUHRING 9005350059500 is a taper length twist drill bit in the Series 535 line, engineered for high-performance drilling in aluminum alloy, cast iron, and steel. The bit measures 15/64 inches (0.2344 inches) in diameter with a 130-degree split point and a parabolic flute profile that promotes fast chip evacuation and reduced cutting force. The 3-19/32-inch flute length delivers a 10xD depth-to-diameter ratio, making it well suited for deeper hole applications where a jobber-length bit falls short. Overall length is 5-15/32 inches. The straight cylindrical shank fits standard drill chucks without adapters.

This drill bit is used in production machining, tool room work, and maintenance applications where consistent hole quality in ferrous and non-ferrous materials is required. The web-thinned, parallel-web construction reduces thrust load at the cutting tip, which is especially beneficial when drilling into cast iron or steel plate. The bright uncoated finish keeps this bit ready for use without additional prep. It is typically run by machinists and metalworking tradespeople using drill presses, CNC machining centers, or hand-held power drills in industrial and maintenance settings.

Key Features

• 15/64 inches diameter with a 130-degree point angle for aggressive, self-centering entry
• Parabolic flute geometry promotes chip clearing in deep holes
• Web-thinned parallel web reduces axial thrust during drilling
• 10xD flute-to-diameter ratio supports drilling up to approximately 3.231 inches deep
• High-speed steel construction suitable for aluminum alloy, cast iron, and steel
• Bright uncoated finish; no coating removal needed before use
• Manufactured to DIN 340 specification for dimensional consistency

Compatibility

Designed for use in materials including aluminum alloy, cast iron, and steel as stated by the manufacturer. The straight cylindrical shank is compatible with standard drill chucks sized for 15/64 inches diameter shanks. Material compatibility and drilling depth are as specified for Series 535 under DIN 340.

Installation Notes

Installation is performed by machinists or maintenance technicians using a drill press, CNC spindle, or hand-held drill with a compatible chuck. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life and maintain hole tolerance. Diameter tolerance is +0.000 to -0.018 mm, so verify fit requirements before starting a production run.
