Guhring 9008340300070 Spiral Flute Tap M30x1.50

Product Description

The GUHRING 9008340300070 is a spiral flute tap designed for metric fine threading in blind hole applications. Built from cobalt high-speed steel with a bright, uncoated finish, this tap cuts M30x1.50 threads to a 6H class of fit. It features a modified bottoming chamfer and four right-hand flutes with a 40-degree helix angle, which promotes efficient chip evacuation in blind hole conditions. At 150 millimeters overall length with a 22 millimeter shank diameter, this tap is suited for use on machining centers and manual tapping setups where precise thread engagement and tool rigidity are required.

This tap is intended for threading operations in steel materials. The modified bottoming chamfer allows threading closer to the bottom of blind holes than a standard plug tap, making it appropriate for applications with limited thread runout. The fast flute style supports higher chip lift in shorter-chipping materials. It is used in industrial manufacturing, toolroom, and maintenance environments where metric fine thread standards are specified.

Key Features

• M30x1.50 metric fine thread form, 6H class of fit with D7/D8 thread limit
• Modified bottoming chamfer for threading close to the bottom of blind holes
• Four right-hand spiral flutes at a 40-degree helix angle for reliable chip evacuation
• Cobalt HSS construction for improved hardness and heat resistance in steel applications
• Bright/uncoated finish; no coolant-through capability required for standard setups
• Series 834 fast flute style optimized for blind hole threading in steel

Compatibility

Designed for blind hole threading in steel workpieces requiring M30x1.50 metric fine threads to a 6H class of fit. Suitable for use in CNC machining centers and manual tapping applications where right-hand thread direction is specified.

Installation Notes

This tap should be installed and operated by qualified machinists or tooling professionals. Ensure the spindle and workpiece are properly secured and aligned before threading operations begin. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain thread quality. Follow machine tool manufacturer guidelines for speed and feed settings appropriate to cobalt HSS taps in steel.
