Titan Usa TT93223 Spiral Point Tap M4x0.7 Metric Hss

Product Description

The TITAN USA TT93223 is a spiral point plug tap designed for metric through-hole threading in a wide range of general-purpose machining applications. It cuts an M4x0.7 thread profile to a 6H class of fit, making it suitable for precision fastener applications where standard metric thread tolerances are required. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, the tap measures 2.125 inches in overall length with a 0.75-inch thread length. The spiral point geometry pushes chips ahead of the cut rather than packing them into the flutes, reducing the risk of tap breakage in through-hole applications. Licensed machinists, tool and die makers, and maintenance technicians are the primary users of this tooling.

This tap is suited for through-hole threading operations in soft to medium-hardness materials on manual mills, drill presses, CNC machining centers, and tapping machines. Its 2-flute spiral point design performs efficiently in general-purpose materials where chip evacuation forward through the hole is possible. The D4 thread limit designation indicates the tolerance range on the major diameter oversize, making it appropriate for standard production tapping of M4 threaded holes where a 6H fit is specified.

Key Features

• M4x0.7 metric thread profile to 6H class of fit for standard production tolerances
• Spiral point geometry pushes chips forward, optimizing performance in through-hole applications
• 2-flute design reduces cutting resistance in general-purpose materials
• High-speed steel construction provides good toughness and wear resistance for general-purpose use
• Plug chamfer with 3-5 lead threads eases entry and reduces starting load
• Bright, uncoated finish suitable for use with standard cutting fluids
• Right-hand thread direction; no coolant-through feature required for standard applications

Compatibility

Designed as a general-purpose M4x0.7 metric spiral point plug tap for through-hole threading in materials suited to HSS tooling. No specific machine or workpiece compatibility data was provided by the manufacturer for this part number.

Installation Notes

This tap is installed and operated by machinists or maintenance technicians using standard tapping machines, drill presses, or CNC equipment with appropriate tapping cycles. Always ensure the workpiece is securely fixtured and the tap is properly aligned with the drilled hole before engagement to prevent breakage. Apply a suitable cutting fluid for the workpiece material to extend tool life and improve thread quality. Inspect the tap for wear or chipping before each use, as HSS tooling in small diameters is susceptible to breakage if forced into an undersized or misaligned hole.
