Guhring 9008300100050 M10x1.00 Metric Fine Machine Tap

Product Description

The GUHRING 9008300100050 is a straight-flute machine tap designed for cutting M10 x 1.00 Metric Fine internal threads in steel workpieces. Part of the Series 830 line, this tap features a cobalt high-speed steel construction with a bright, uncoated finish. The modified bottoming chamfer allows threading closer to the bottom of blind holes compared to standard plug or taper chamfer styles. With three straight flutes and a right-hand thread direction, it is suited for use in CNC machining centers, manual lathes, and tapping machines. Overall length is 90 millimeters, shank diameter is 7.00 millimeters, and square drive size is 5.50 millimeters.

This tap is used in metalworking and machining applications where Metric Fine thread tolerance class 6H is required. It supports both blind hole threading and through-hole threading in steel materials. The modified bottoming chamfer makes it especially useful in blind holes where full thread depth close to the bottom is needed. Typical users include machinists, tool and die makers, and maintenance technicians working on precision metal components.

Key Features

• Modified bottoming chamfer for threading near the bottom of blind holes
• Cobalt HSS construction for improved wear resistance in steel applications
• Bright, uncoated finish for a clean, sharp cutting edge right out of the box
• Three straight flutes suit standard through-hole and blind hole tapping operations
• Thread limit D4/D5 provides compatibility with standard 6H tolerance class fits
• No coolant-through design keeps tool construction simple for conventional tapping setups

Compatibility

Designed for cutting M10 x 1.00 Metric Fine, right-hand, class 6H internal threads in steel. Suitable for use in standard tapping chucks and holders that accept a 7.00-millimeter round shank with a 5.50-millimeter square drive.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with tapping operations. Always secure the workpiece properly and ensure the tapping machine or CNC spindle is correctly aligned with the hole axis before engaging the tap. Use appropriate tapping fluid or cutting oil for steel to extend tool life and maintain thread quality. Inspect the tap for wear or chipping before each use, and never back-drive a worn or broken tap by force.
