Guhring 9003050014500 Cobalt Jobber Drill 1.45mm

Product Description

The GUHRING 9003050014500 is a cobalt jobber-length drill bit designed for general-purpose drilling in ferrous metals. The bright, uncoated cobalt construction provides solid heat resistance and edge retention in demanding applications. It features a 1.45 mm diameter, a 118-degree cone relief point, and a two-flute right-hand spiral configuration. The overall length is 40 mm, with an 18 mm flute length and a 22 mm straight-cylindrical shank. The web-thinned tip reduces entry force and helps center the bit at the start of a cut. This bit is built to DIN 338 standards and carries an h8 diameter tolerance, making it suitable for precision work where consistent hole size matters.

This drill bit is intended for use in cast iron and steel workpieces in both shop and field environments. The regular spiral and 5xD flute-to-diameter ratio make it well suited for through-hole drilling in light-to-medium stock. It is commonly used by machinists, maintenance technicians, and fabricators working with ferrous base materials where a general-purpose cobalt bit is the appropriate tool. The straight-cylindrical shank fits standard drill chucks without adapters.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or technicians familiar with proper drilling procedures. Secure the workpiece and ensure the drill chuck is fully tightened before operation. Refer to applicable shop safety standards and machine manufacturer guidelines for spindle speed and feed rate settings appropriate to the workpiece material. This bit does not support coolant-through delivery; apply cutting fluid externally as needed when drilling steel.
