Accupro T2660606 Spiral Point Tap M16 X 2 4 Flute

Product Description

The ACCUPRO T2660606 is a spiral point tap designed for threading M16 x 2 holes in steel workpieces. With 4 flutes and a plug chamfer, it pushes chips forward through the hole, making it well suited for through-hole tapping operations on CNC machines and manual drill presses. The tap is manufactured from 3% vanadium high speed steel for improved wear resistance and edge retention compared to standard HSS. A bright finish is applied without additional coating, keeping the tool cost-effective for general-purpose production work. Overall length is 98.5 mm with a 32 mm thread length and a 12.19 mm shank diameter.

This tap is intended for tapping steels in production and job-shop environments. The spiral point geometry drives chips ahead of the cutting action, reducing chip packing in through-hole applications. It is a right-hand tap for use with standard right-hand M16 x 2 thread forms. Machinists, tool-and-die makers, and maintenance technicians working with metric fastener sizes in steel fabrication, machine assembly, and repair will find this a direct-application tool for their setups.

Key Features

• M16 x 2 metric thread size with right-hand thread direction
• 4-flute spiral point geometry pushes chips forward for through-hole tapping
• Plug chamfer provides a balance between starting ease and thread engagement
• 3% vanadium high speed steel construction for extended tool life in steels
• Bright finish suitable for general-purpose dry or flood-coolant tapping
• D6 thread limit for standard tolerance metric threads

Compatibility

Designed for tapping through holes in steels requiring a right-hand M16 x 2 metric thread. Suitable for use in standard tap holders and CNC rigid tapping chucks accepting a 12.19 mm shank diameter.

Installation Notes

This tap is installed and operated by a machinist or maintenance technician using a tap holder, tapping head, or CNC spindle with rigid tapping capability. Secure the workpiece fully before tapping and ensure the tap is aligned perpendicular to the hole axis to prevent tap breakage. Use an appropriate cutting fluid for steel to reduce heat and extend tool life. Inspect the tap for wear or damage before each use and replace if cutting edges show signs of chipping or dullness.
