Guhring 9041200060000 Spiral Flute Tap M6 X 1.00

Product Description

The GUHRING 9041200060000 is a spiral flute tap designed for threading blind holes in metric coarse applications. It cuts an M6 x 1.00 thread to a 6H class of fit using a 3-flute, right-hand spiral configuration with a 40-degree helix angle. The modified bottoming chamfer allows threading closer to the bottom of a blind hole than a standard plug tap. Manufactured from powdered metal with a TiN (titanium nitride) coating, this tap offers increased hardness and wear resistance compared to standard high-speed steel. Overall length is 3.15 inches. It is installed by machinists, toolmakers, and maintenance technicians working with threaded metal components.

This tap is rated for use in high-tensile steel and is suited to blind hole threading operations on CNC machining centers, drill presses, and tapping machines. The fast flute style promotes efficient chip evacuation in the spiral direction, helping to clear chips from the hole during the tapping cycle. The 40-degree helix angle supports smooth cutting action in tougher materials. Coolant-through capability is not present on this tap. This is a right-hand thread, right-hand flute tool from the GUHRING Series 4120 product line.

Compatibility

Designed as an OEM-style spiral flute tap for blind hole threading in high-tensile steel workpieces requiring an M6 x 1.00 metric coarse thread to a 6H class of fit. Compatible with standard tapping chucks and holders accepting a 0.255-inch shank diameter.

Installation Notes

This tap is installed by machinists and toolroom technicians using a tapping chuck, CNC rigid tapping holder, or manual tap wrench sized for a 0.255-inch shank. Secure the workpiece firmly before tapping and ensure the tap is aligned perpendicular to the workpiece surface. Apply appropriate cutting fluid for the material being tapped. Do not reverse-drive the tap under power without confirming the machine control supports synchronized tapping to avoid tool breakage.
