Guhring 9006520016500 Jobber Drill Bit 1.65mm Hss Tin

Product Description

The GUHRING 9006520016500 is a jobber-length twist drill bit designed for precision hole-making in light metals, plastics, and similar materials. Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, it offers improved surface hardness and wear resistance over uncoated HSS bits. The bit measures 1.65 mm (0.0650 inches) in diameter with a 130-degree split point and a parabolic flute geometry that promotes efficient chip evacuation. It carries a web-thinned, tapered web configuration for reduced thrust and cleaner entry. Licensed HVAC, plumbing, and mechanical tradespeople as well as industrial machinists rely on this size for small-diameter precision drilling tasks.

This drill bit is rated for primary use in aluminum and non-ferrous metals (material group codes K, N, and P per DIN classification). It suits residential and light commercial maintenance work, sheet metal fabrication, and production drilling applications where a 1.65 mm hole diameter is required. The straight-cylindrical shank fits standard drill chucks without adapters. The parabolic flute runs at a 5xD flute-to-diameter ratio, giving adequate flute length for the 0.6900-inch maximum drilling depth. The bit conforms to DIN 338 standards and is part of the GUHRING Series 652 high-performance lineup.

Key Features

• 1.65 mm (0.0650 inch) diameter with diameter tolerance of -0.014 to 0.000 mm for precision fit
• TiN coating increases surface hardness and extends tool life compared to bare HSS
• 130-degree point angle with web thinning reduces entry thrust and improves centering
• Parabolic flute design at 5xD ratio promotes fast, clean chip removal
• Right-hand cut with straight-cylindrical shank for universal chuck compatibility
• Manufactured to DIN 338 specification for consistent dimensional accuracy

Compatibility

Designed as a DIN 338-compliant jobber-length drill bit suitable for standard drill chucks accepting a 0.0650-inch straight-cylindrical shank. Rated for aluminum, non-ferrous metals, and plastics per material group codes K, N, and P.

Installation Notes

This bit is installed and operated by machinists, maintenance technicians, or tradespeople using a standard drill press, CNC drill, or hand drill with an appropriate chuck size. Secure the shank fully in the chuck before operation and verify chuck key is removed before powering the tool. Do not exceed the maximum drilling depth of 0.6900 inches in a single pass without retracting to clear chips. Use appropriate cutting fluid or lubricant when drilling metals to extend tool life and maintain dimensional accuracy.
