Titan Usa TT93244TIN M8x1.25 Spiral Point Plug Tap Hss Tin

Product Description

The TITAN USA TT93244TIN is a spiral point plug tap designed for metric through-hole threading in a wide range of general-purpose machining applications. Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, this tap delivers improved wear resistance and extended tool life compared to uncoated alternatives. It cuts an M8x1.25 thread in right-hand direction, holds a 6H class of fit, and carries a D5 thread limit for consistent dimensional accuracy. With a 2-flute spiral point geometry, it pushes chips forward ahead of the cut, keeping the flutes clear during through-hole operations.

This tap is suited for production and maintenance environments where M8x1.25 metric threads are required in through-hole configurations. The plug chamfer — typically 3 to 5 threads — allows the tap to start easily in a pre-drilled hole and reach near-full thread depth without a starter tap. It is commonly used by machinists, tool-and-die technicians, and maintenance mechanics working with steel, aluminum, and other general-purpose materials on manual or CNC equipment.

Key Features

• M8x1.25 metric thread, right-hand cut, 6H class of fit
• 2-flute spiral point geometry pushes chips forward for clean through-hole threading
• Plug chamfer for easy starting and efficient thread engagement
• HSS construction with TiN coating for extended wear resistance
• D5 thread limit for consistent tolerance control
• No coolant-through requirement — suited for standard shop setups

Compatibility

Designed as an OEM-style replacement or standard tooling selection for general-purpose M8x1.25 metric through-hole tapping operations across compatible tap holders and tapping heads that accept standard straight-shank metric taps.

Installation Notes

Installation is performed by machinists or maintenance technicians using a tap wrench, tapping head, or CNC rigid tapping setup. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for M8x1.25 before beginning. Apply appropriate cutting fluid for the workpiece material to reduce friction and heat buildup. Never reverse the tap under power without confirming the machine is configured for reverse-thread extraction.
