Guhring 9003050055600 Cobalt Drill Bit 7/32 Inch

Product Description

The GUHRING 9003050055600 is a cobalt jobber length drill bit designed for general-purpose drilling in demanding metalworking applications. Built to DIN 338 standards, it measures 7/32 inch (0.2188 inch decimal) in diameter with an overall length of 93 mm and a flute length of 57 mm. The 118-degree standard point angle and web-thinned, tapered web geometry help reduce entry force and improve chip clearance. An oxide coating over the cobalt steel body provides added surface hardness and heat resistance. This bit is suited for trade professionals and machinists who need consistent performance in ferrous metals.

The 9003050055600 is intended for drilling into cast iron and steel, covering primary workpiece material codes K and P. The right-hand spiral flute with regular helix and straight-cylindrical shank seats cleanly in standard drill chucks. At a 5xD flute-to-diameter ratio, the bit handles depths up to 1.916 inches (48.66 mm). It is appropriate for use in manual drill presses, CNC drilling operations, and handheld power tools where a jobber-length bit is the specified format. Series 305 positions it within the GUHRING general-purpose line.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with metalworking equipment. Ensure the workpiece is securely clamped and the drill chuck is tightened before operation. Power down all equipment before inserting or removing the bit from the chuck. Do not exceed the rated maximum drilling depth of 1.916 inches in a single pass without appropriate chip-clearing intervals.
