Accupro T2660314 Spiral Point Tap M6 X 1 Plug 3 Flutes

Product Description

The ACCUPRO T2660314 is a spiral point tap designed for threading M6 x 1 metric holes in steel workpieces. It features a 3-flute plug chamfer geometry that pushes chips ahead of the cutting action, making it well suited for through-hole tapping operations. Manufactured from 3% Vanadium High Speed Steel, the tap offers improved wear resistance and edge retention compared to standard HSS tooling. The bright finish provides a clean, uncoated surface that is appropriate for general-purpose threading applications. With a 65 mm overall length and 19 mm thread length, it fits standard tap holders and is sized for M6 threading tasks in production and maintenance machining environments.

This tap is intended for right-hand threading in steel materials. The plug chamfer style requires a drilled or bored through-hole to allow chips to exit ahead of the tap. It is commonly used in machine shops, manufacturing facilities, and maintenance repair operations where M6 x 1 metric threads are required in mild to medium-hardness steels. The D4 thread limit provides a controlled fit tolerance appropriate for standard metric fastener engagement. It is suitable for use in CNC machining centers, drill presses, and hand tapping fixtures where a rigid or floating holder is employed.

Key Features

• M6 x 1 metric thread size with right-hand cutting direction
• 3-flute spiral point geometry pushes chips forward through the hole
• Plug chamfer style for through-hole tapping applications
• 3% Vanadium High Speed Steel construction for enhanced wear resistance
• D4 thread limit for controlled metric thread fit tolerance
• Bright finish suitable for general-purpose steel threading without coating

Compatibility

Designed as an OEM-style replacement or standard tooling option for M6 x 1 metric through-hole tapping operations in steel materials using standard tap holders compatible with a 6.48 mm shank diameter.

Installation Notes

This tap is installed by machinists and tooling technicians using a standard tap holder, collet chuck, or floating tap adapter. Ensure the workpiece is properly fixtured and that the correct M6 x 1 tap drill size has been used prior to tapping. Apply appropriate cutting fluid for the material being threaded to prolong tool life. This tap is not designed for blind-hole applications due to its spiral point chip-pushing geometry.
