Guhring 9006510016400 Jobber Drill 1.64 Mm Hss Tin

Product Description

The GUHRING 9006510016400 is a high speed steel jobber-length twist drill with a titanium nitride (TiN) coating, designed for general-purpose drilling in metalworking applications. The drill measures 1.64 mm in diameter with a 118-degree cone relief point and a two-flute right-hand spiral configuration. Overall length is 43 mm with a 20 mm flute length and a straight-cylindrical shank. The web-thinned tip reduces cutting resistance and helps maintain accurate entry, making this drill suitable for production and maintenance environments where consistent hole quality is required.

This drill is intended for use in cast iron and steel workpieces and fits standard drill chucks accepting a 1.64 mm straight-cylindrical shank. The Series 651 designation follows DIN 338 standards, placing this in the regular-spiral, general-purpose jobber category. Maximum drilling depth is 17.54 mm. It is suited for use in CNC machining centers, drill presses, and hand-held power tools by machinists, tool-and-die technicians, and industrial maintenance professionals. Coolant-through is not supported on this model.

Compatibility

Designed for drilling cast iron and steel workpieces. Compatible with any standard drill chuck accepting a 1.64 mm straight-cylindrical shank. Suitable for general-purpose use across machine shop and industrial maintenance applications per DIN 338 Series 651 specifications.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with drill press and CNC machine operation. Secure the shank fully in the drill chuck and verify runout before beginning a cut. Power down and lock out the machine before changing or inspecting the drill. Do not exceed the maximum drilling depth of 17.54 mm in a single pass without retracting to clear chips.
