Guhring 9041200160000 Spiral Flute Tap M16 X 2.00

Product Description

The GUHRING 9041200160000 is a spiral flute tap designed for metric coarse blind hole threading in high-tensile steel. It carries an M16 x 2.00 thread size with a 4-flute, right-hand spiral configuration and a 40-degree helix angle suited for fast chip evacuation in tough materials. The modified bottoming chamfer allows threading closer to the bottom of a blind hole than a standard taper or plug chamfer. Finished with a TiN coating, the tap offers increased surface hardness and lubricity. It is manufactured from powdered metal for improved wear resistance and toughness. The overall length is 4.331 inches.

This tap is intended for use in blind hole threading applications where metric coarse threads are required in high-tensile steel workpieces. The 6H class of fit targets standard tolerance threading consistent with general-purpose metric fastener assemblies. The fast flute style and 40-degree helix angle promote efficient chip removal in deep or interrupted blind holes. It is suited for use in CNC machining centers, manual tapping heads, and drill press setups in production or job shop environments. The shank diameter of 0.48 inches fits standard tap holders and chucks sized for M16 tooling.

Key Features

• M16 x 2.00 metric coarse thread form with 6H class of fit
• Modified bottoming chamfer for threading close to the bottom of blind holes
• 40-degree right-hand spiral flute promotes chip evacuation in high-tensile steel
• Powdered metal construction for improved toughness and wear resistance
• TiN finish increases surface hardness and reduces friction during cutting
• No coolant-through design; suitable for standard external coolant or cutting fluid application

Compatibility

Designed for blind hole threading applications in high-tensile steel. Thread limit rating is D6 and D7, within the 6H class of fit. Part of the GUHRING Series 4120 spiral flute tap line.

Installation Notes

Installation is performed by machinists and CNC operators using a calibrated tap holder or floating tap chuck sized for the 0.48-inch shank diameter. Ensure the workpiece is securely fixtured and the spindle is set to the correct feed rate matching the 2.00 mm pitch before engaging. Apply appropriate cutting fluid or tapping compound for high-tensile steel to reduce heat and extend tool life. Do not reverse the tap under load without confirming the machine control is set for synchronized tapping to avoid thread damage or tap breakage.
