Guhring 9006220043000 Cobalt Jobber Drill Bit No 18

Product Description

The GUHRING 9006220043000 is a cobalt jobber-length drill bit sized to wire gauge No. 18, equivalent to 0.1695 inches in diameter. Built to DIN 338 standards, it features a 130-degree split point and a parabolic flute geometry that clears chips aggressively at higher feed rates. The straight-cylindrical shank measures 0.1693 inches in diameter and seats securely in standard three-jaw or keyless chucks. Web-thinned with a tapered web configuration, this bit reduces entry thrust and improves self-centering on entry. It carries a bright, uncoated finish and is rated as a high-performance grade cobalt tool suited for production drilling environments where heat and wear resistance matter.

This bit is designed for drilling aluminum and similar non-ferrous and low-to-medium alloy materials, corresponding to workpiece material codes K, N, and P per standard classification. The parabolic flute and 130-degree point geometry make it well-suited for high-speed drilling in sheet metal, structural aluminum, and fabrication shop applications. With an overall length of 3-5/32 inches and a flute length of 1-27/32 inches, it fits standard benchtop drill presses, CNC machining centers, and handheld pneumatic or electric drills. The 5xD flute-to-diameter ratio supports a maximum drilling depth of 1.5960 inches without the need for peck cycles in most setups.

Key Features

• Cobalt high-performance grade material provides elevated heat and wear resistance versus standard HSS
• 130-degree point angle reduces thrust and improves centering on entry into aluminum and non-ferrous stock
• Parabolic flute design promotes fast chip evacuation at higher feed rates
• Web-thinned tapered web lowers cutting force at the chisel edge
• DIN 338 specification ensures dimensional consistency and interchangeability
• Bright uncoated finish compatible with standard cutting fluids and dry drilling applications

Compatibility

Designed as an OEM-specification replacement or direct-use jobber drill conforming to DIN 338, suitable for use in standard drill press, CNC, or handheld drill chucks accepting a 0.1693-inch straight-cylindrical shank.

Installation Notes

Installation of this drill bit should be performed by a qualified machinist or tool-and-die technician. Secure the shank fully in the chuck and verify concentricity before beginning a drilling cycle. Always power down the spindle and lock out the machine before changing bits. Use appropriate cutting fluid or coolant for the workpiece material when operating at elevated speeds to extend tool life.
