Guhring 9008270180080 Spiral Point Tap M18x2 Cobalt

Product Description

The GUHRING 9008270180080 is a spiral point tap designed for through-hole threading in steel and other ferrous materials. Built from cobalt high-speed steel with a bright finish, it delivers durability and heat resistance in demanding cutting applications. The plug chamfer configuration makes it suited for through-hole work, while the 4-flute geometry and spiral point design push chips forward ahead of the tap during cutting. The 6H thread limit and D6/D7 tolerance classification ensure consistent thread quality within standard metric fit requirements. Overall length is 125 millimeters, with a shank diameter of 14 millimeters. This tap is typically installed and used by machinists and maintenance mechanics in production or field threading operations.

This tap is intended for right-hand through-hole threading applications in steel. It produces M18 x 2.00 metric fine threads conforming to the 6H class of fit and D6/D7 thread limit. It is part of GUHRING Series 827 and is suited for use in CNC machining centers, drill presses, or hand-tapping setups where a through-hole configuration is present. No coolant-through feature is present on this tap, so external cutting fluid application is recommended when threading steel at higher feed rates or in deeper through-holes.

Key Features

• Cobalt HSS construction for improved heat and wear resistance when threading steel
• Spiral point design pushes chips forward, reducing clogging in through-hole applications
• 4-flute geometry provides balanced cutting action and thread form consistency
• Plug chamfer provides gradual thread engagement for through-hole starts
• 6H class of fit with D6/D7 thread limit for standard metric tolerance compliance
• Bright finish with no coating for straightforward regrinding and tool maintenance

Compatibility

Designed for through-hole threading of M18 x 2.00 metric fine threads in steel. Compatible with standard tap holders and chucks accepting a 14 millimeter shank diameter.

Installation Notes

This tap should be installed by qualified machinists or maintenance personnel familiar with threading tooling and machine setup. Secure the tap in a properly sized tap holder or floating tap chuck to allow for axial float and prevent tap breakage. Always apply cutting fluid rated for the workpiece material when threading steel. Inspect the tap for wear or chipping before each use and replace if thread quality degrades.
