Guhring 9006090045000 Carbide Drill Bit No. 16 0.1772 in

Product Description

The GUHRING 9006090045000 is a jobber-length, solid carbide drill bit designed for precision hole-making in demanding machining applications. Built to DIN 6539 standards, this bit features a 150-degree split point, three spiral flutes, and a titanium nitride (TiN) coating that extends tool life in abrasive materials. The drill diameter measures 0.1772 inches (No. 16 wire gauge), with an overall length of 2.283 inches and a flute length of 1.260 inches. Web thinning and a tapered web configuration reduce thrust and improve chip evacuation. Series 609 submicron carbide construction delivers rigidity and edge retention well beyond standard high-speed steel tooling. Installed by machinists and toolroom technicians across production and maintenance environments.

This drill bit is suited for close-tolerance drilling in ferrous and non-ferrous metals, plastics, and composites where dimensional accuracy is critical. The self-centering 150-degree point geometry eliminates the need for a center punch on most materials and reduces walking on entry. The straight-cylindrical shank seats directly in standard drill chucks, collet chucks, and toolholders with a matching bore. A 5xD flute-to-diameter ratio and a maximum drilling depth of 0.994 inches make this bit appropriate for short, through-hole, and blind-hole work in both CNC machining centers and conventional drill presses.

Key Features

• Solid submicron carbide construction for superior hardness and edge retention compared to HSS
• Titanium nitride (TiN) coating reduces friction and extends tool life in abrasive and hard materials
• 150-degree self-centering point eliminates center-punch step and reduces drill walk on entry
• Three-flute spiral design improves chip evacuation and hole-surface finish
• Web-thinned, tapered web lowers cutting thrust and reduces heat buildup
• Manufactured to DIN 6539 standard with diameter tolerance of -0.012 to 0.000 mm for consistent fit

Compatibility

Designed as an OEM-specification replacement or direct-purchase tooling option for any application requiring a No. 16 wire-gauge (0.1772 inch) jobber-length drill bit with a straight-cylindrical shank in standard drill chucks or collet toolholders.

Installation Notes

Installation and use should be performed by qualified machinists familiar with cutting tool setup and machine operation. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the straight-cylindrical shank fully in a matching chuck or collet and verify runout before cutting. Follow the tool manufacturer and machine builder guidelines for speed, feed, and coolant — this bit does not support through-spindle coolant delivery.
