Guhring 9008300300070 M30x1.50 Machine Tap Cobalt

Product Description

The GUHRING 9008300300070 is a straight-flute machine tap designed for cutting M30x1.50 metric fine internal threads in steel. Built from cobalt high-speed steel with a bright, uncoated finish, this tap delivers consistent thread quality in both blind-hole and through-hole applications. The modified bottoming chamfer allows threading close to the bottom of a blind hole, making it well-suited for tight-tolerance work. With four flutes and a right-hand thread direction, it is engineered for use in CNC machining centers, drill presses, and other power tapping equipment. Overall length is 150 millimeters, with a shank diameter of 22 millimeters and a square drive size of 18 millimeters.

This tap is intended for metric fine threading operations in steel workpieces, covering both blind-hole and through-hole scenarios. The 6H class of fit and D7/D8 thread limit designation make it appropriate for standard metric fine tolerance applications. It belongs to GUHRING Series 830 and is sold individually. Typical users include machinists, toolroom technicians, and maintenance professionals requiring precise metric fine taps for production or repair work.

Compatibility

Designed for blind-hole and through-hole threading in steel workpieces requiring M30x1.50 metric fine threads at a 6H class of fit with D7 or D8 thread limit.

Installation Notes

Installation and use should be performed by qualified machinists familiar with tapping operations and machine tool setup. Power down and secure the machine before mounting or changing the tap in the holder. Use an appropriate tap holder sized for the 22-millimeter shank and 18-millimeter square drive. Always apply suitable cutting fluid for steel tapping to reduce heat buildup and extend tool life.
