Titan Usa TT91040 Spiral Point Plug Tap 10-32 Unf Hss

Product Description

The TITAN USA TT91040 is a spiral point plug tap designed for through-hole threading in a 10-32 UNF thread profile. Built from high-speed steel (HSS) with a bright, uncoated finish, it produces clean internal threads in general-purpose materials including mild steel, aluminum, and similar workpiece stock. The plug chamfer distributes cutting load gradually across the lead threads, reducing the risk of tap breakage on entry. With a 2-flute spiral point geometry, the tap pushes chips forward ahead of the cutting zone, keeping the flutes clear during production runs. This tap suits machine-shop technicians, maintenance machinists, and trade professionals threading fastener holes in HVAC equipment panels, electrical enclosures, and light structural components.

The TT91040 is sized for 10-32 UNF through-hole applications where chip evacuation ahead of the tap is preferred over chip extraction. The H3 thread limit designation suits standard 2B and 3B class-of-fit tolerances, making it appropriate for general-purpose threaded connections. The right-hand cutting direction is compatible with conventional tapping heads, drill press setups, and hand-tapping operations. It is well-suited for single-piece repair work as well as short-run production environments where a reliable, no-frills HSS tap is needed without the overhead of coated tooling.

Key Features

• Spiral point geometry pushes chips forward, ideal for through-hole threading without chip packing
• Plug chamfer provides a gradual lead for reduced tap breakage on entry
• H3 thread limit supports 2B and 3B class-of-fit tolerances for general-purpose threaded connections
• High-speed steel construction handles general-purpose materials in standard cutting conditions
• Bright, uncoated finish suited for use with cutting fluid in standard machine or hand-tapping operations
• Right-hand thread direction compatible with standard tapping heads and reversible drill presses

Compatibility

Designed for through-hole threading in general-purpose materials at 10-32 UNF. Compatible with standard 2B and 3B class-of-fit threaded hole requirements. Suitable for use in tapping heads, CNC machining centers, drill presses, and hand-tapping applications that accept a 0.194-inch shank diameter.

Installation Notes

This tap is intended for use by machinists and qualified trade professionals. Always ensure the workpiece is securely fixtured before tapping. Use a compatible cutting fluid or tapping compound to extend tool life and improve thread finish. Do not reverse the tap into a blind hole with this spiral point style, as it is designed specifically for through-hole applications where chips can exit ahead of the tap.
