Guhring 9008270180050 Spiral Point Tap M18x1 Cobalt

Product Description

The GUHRING 9008270180050 is a spiral point tap designed for through-hole threading in steel and similar materials. It cuts a Metric Fine M18 x 1.00 mm pitch thread and is built from cobalt high-speed steel, which holds cutting edge hardness under the heat generated in tougher workpiece materials. The plug chamfer distributes the cutting load across several leading threads for smooth entry in through-hole applications. With a 6H thread class of fit and D4/D5 thread limit, this tap produces threads within standard tolerance for general mechanical assemblies. Licensed machinists, toolroom technicians, and maintenance professionals use this tool in manual and CNC tapping operations.

This tap is suited for through-hole tapping operations in steel workpieces where a Metric Fine M18 x 1.00 mm thread is required. The plug chamfer style makes it appropriate for applications where the tap can run fully through the part. The 4-flute design provides chip ejection ahead of the tap into the hole exit, keeping the flutes clear during the cut. Series 827 identifies the GUHRING product line for this style and size range. Typical use cases include fabrication, repair, and production threading where Metric Fine threads are specified.

Key Features

• Cobalt high-speed steel construction for improved heat and wear resistance in steel applications
• 4-flute spiral point geometry pushes chips forward through the hole for clean through-hole threading
• Plug chamfer distributes cutting load and guides the tap into the workpiece smoothly
• 6H class of fit with D4/D5 thread limit for standard Metric Fine tolerance requirements
• Bright finish with no coating keeps tool cost straightforward for general-purpose tapping
• Right-hand thread direction; no coolant-through feature required for most standard applications

Compatibility

Designed for through-hole threading applications requiring a Metric Fine M18 x 1.00 mm thread in steel. Compatible with standard tap holders and collets sized for a 14.00 mm shank diameter.

Installation Notes

This tap should be installed by a qualified machinist or toolroom technician in a properly aligned tap holder or tapping head. Always secure the workpiece before operation and confirm the holder provides the correct shank clearance for a 14.00 mm shank. Use appropriate cutting fluid for steel to prolong tool life and improve thread finish. Do not reverse the tap under load without ensuring the machine or wrench is rated for the torque required by this thread size and material.
