Emuge C0208400.0120 Spiral Point Tap M20x2.5 Tin Hss-e

Product Description

The EMUGE C0208400.0120 is a spiral point tap designed for right-hand through-hole threading in metric M20x2.5 applications. Built from HSS-E cobalt high-speed steel and finished with a TiN (titanium nitride) coating, it delivers extended tool life in steel machining environments. The plug chamfer eases entry and distributes cutting load across the leading threads. With a 6H class of fit and D7 thread limit, this tap produces threads to standard metric tolerance for general mechanical assembly. It is suited for use in CNC machining centers, drill presses, and manual tapping operations where consistent thread quality in through-hole configurations is required.

This tap is intended for through-hole threading operations in steel workpieces. The spiral point geometry pushes chips forward ahead of the tap, keeping the flutes clear and reducing the risk of chip packing in production runs. With 3 flutes and a 32 mm thread length, it handles the full M20x2.5 thread depth needed in most structural and mechanical applications. The TiN coating reduces friction and improves wear resistance, making it well-suited for medium to high-volume threading in ferrous materials. Machinists and toolroom technicians working in manufacturing, maintenance, and fabrication environments are the primary users.

Key Features

• Spiral point geometry pushes chips forward - optimized for through-hole threading in steel
• HSS-E cobalt substrate provides higher heat and wear resistance compared to standard HSS
• TiN coating reduces cutting friction and extends tool life in ferrous materials
• Plug chamfer for easy thread entry and load distribution across leading threads
• 6H class of fit with D7 thread limit for standard metric tolerance threads
• No coolant-through requirement - compatible with flood or external coolant delivery

Compatibility

Designed for M20x2.5 metric through-hole threading in steel workpieces. Compatible with standard tap holders and floating tap chucks accepting a 16 mm shank with a 12 mm square drive. Part of the EMUGE Series C0208400.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician. Secure the tap in a rigid or floating tap holder appropriate for the machine spindle and workpiece material. Ensure the machine spindle is fully stopped and the workpiece is clamped before tool changes. Apply appropriate cutting fluid or flood coolant to the threading zone to manage heat and chip evacuation. Do not reverse the tap under power without confirming the machine is programmed for rigid tapping or that a floating holder is in use.
