Guhring 9005350020600 Taper Length Drill Bit 0.0810 in

Product Description

The GUHRING 9005350020600 is a taper length twist drill bit engineered for precision hole-making in aluminum alloy, cast iron, and steel. Built from high speed steel with a bright/uncoated finish, this Series 535 drill runs a 130-degree point angle optimized for fast penetration and accurate positioning across a range of workpiece materials. The parabolic flute geometry promotes efficient chip evacuation, reducing heat buildup and extending tool life in production environments. The cylindrical shank measures 0.0811 inches in diameter and the bit delivers a diameter tolerance of +0.000 to -0.014 mm, making it suitable for close-tolerance applications in metalworking and fabrication shops.

This drill bit is intended for use in machining operations where a longer flute length is required to reach greater drilling depths than a standard jobber drill allows. With a flute length of approximately 2.219 inches and an overall length of approximately 3.344 inches, the 9005350020600 handles maximum drilling depths up to 2.083 inches, achieving a 10xD flute-to-diameter ratio. It is suited for right-hand rotation in CNC machining centers, drill presses, and hand-held power tools used by machinists and tool-and-die professionals in light industrial and job-shop settings.

Key Features

• 0.0810-inch diameter with a wire gauge equivalent of #46 for precise sizing reference
• 130-degree standard point angle for aggressive cutting entry across multiple metal types
• Parabolic flute design improves chip flow and reduces clogging in deep-hole applications
• Web-thinned parallel web construction reduces thrust force at entry
• High speed steel construction provides wear resistance in aluminum alloy, cast iron, and steel
• DIN 340 specification ensures dimensional consistency for replacement and interchangeability

Compatibility

Designed as an OEM-specification taper length drill bit conforming to DIN 340 standards, suitable for use in standard cylindrical-shank drill chucks and collet holders accepting 0.0811-inch shank diameters.

Installation Notes

Installation is performed by machinists and metalworking professionals using a compatible drill chuck or collet holder rated for the shank diameter. Verify spindle speed and feed rate recommendations for the target material before operation, as high speed steel tooling has defined operating limits in hard or abrasive workpieces. Secure the shank fully in the chuck to minimize runout, and inspect the cutting edges for wear or damage before each use. No coolant-through feature is present on this bit, so external coolant or cutting fluid application is recommended for extended runs in steel or cast iron.
