Titan Usa TT93250TIN M10x1.5 Spiral Point Plug Tap Tin Hss

Product Description

The TITAN USA TT93250TIN is a spiral point plug tap designed for through-hole threading in metric applications. Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, this tap cuts M10x1.5 threads to a 6H class of fit with a D6 thread limit. The plug chamfer — typically 3 to 5 lead threads — allows the tap to enter a hole progressively, making it well-suited for production and general-purpose threading on through holes. The spiral point geometry pushes chips forward ahead of the cutting zone, reducing chip clogging and supporting consistent thread quality across moderate-volume runs. Machinists, toolmakers, and maintenance mechanics are the typical end users.

This tap is sized for M10x1.5 metric threads and is suited for general-purpose through-hole threading on ferrous and non-ferrous materials in both shop and field environments. The TiN coating increases surface hardness and reduces friction at the cutting edge, extending tool life versus uncoated HSS in repetitive threading operations. At 2.9375 inches overall length with a 1.25-inch thread length, the tap fits standard tap holders and machine spindles used in drill presses, CNC machining centers, and hand tapping operations.

Key Features

• M10x1.5 metric thread form with 6H class of fit and D6 thread limit for controlled tolerance threading
• Spiral point geometry pushes chips forward — optimized for through-hole applications only
• Plug chamfer (3 to 5 lead threads) for progressive entry and reduced starting force
• TiN coating improves wear resistance and reduces built-up edge on the cutting face
• 3-flute design balances chip clearance and cutting-edge support in general-purpose materials
• Right-hand thread direction, no coolant-through feature, not intended for interrupted threads

Compatibility

Designed for general-purpose through-hole threading in M10x1.5 metric applications. Fits standard tap holders, floating tap holders, and rigid tapping chucks sized for the 0.381-inch shank diameter used in this series.

Installation Notes

This tap is intended for through-hole threading only — do not use it in blind holes where chip evacuation is restricted. Secure the workpiece fully before tapping and apply appropriate cutting fluid for the base material being threaded. Use a calibrated torque-limiting tap holder in CNC or production settings to reduce the risk of tap breakage. Inspect the cutting edges for wear or chipping before each use, as a damaged tap will produce out-of-tolerance threads.
