Accupro 31034-00T Spiral Point Tap M4 X 0.7 Metric Coarse

Product Description

The ACCUPRO 31034-00T is a spiral point tap designed for cutting M4 x 0.7 metric coarse internal threads in through-hole applications. Manufactured from powdered metal with a titanium nitride (TiN) coating, this tap offers improved wear resistance and heat dissipation compared to standard high-speed steel tooling. The spiral point geometry pushes chips forward ahead of the cutting zone, making it well suited for through-hole tapping where chip evacuation is a primary concern. With 3 flutes, a plug chamfer, a 6H class of fit, and a D4 thread limit, it delivers consistent thread quality in a wide range of workpiece materials.

This tap is used in machining, maintenance, and fabrication environments where metric coarse threads in the M4 range are required. It is appropriate for through-hole tapping on CNC machining centers, drill presses, and manual tapping setups. The TiN finish makes it a practical choice for production runs on steel, cast iron, and similar ferrous materials. It is commonly used by machinists, tool-and-die technicians, and maintenance mechanics working on equipment assemblies, fixtures, and structural components that require reliable small-diameter metric threads.

Key Features

• M4 x 0.7 metric coarse thread form for standard metric fastener compatibility
• Spiral point geometry advances chips forward, ideal for through-hole applications
• Powdered metal construction provides greater wear resistance than conventional HSS
• TiN coating reduces friction and extends tool life in ferrous materials
• 6H class of fit and D4 thread limit ensure consistent, on-tolerance threads
• Right-hand thread direction; no coolant-through feature

Compatibility

Designed as a standard spiral point tap for through-hole metric coarse tapping operations; confirm workpiece material and machine setup compatibility before use.

Installation Notes

Tapping operations should be performed by a qualified machinist using appropriate cutting fluid or tapping compound for the workpiece material. Ensure the tap is properly aligned with the drilled hole before engagement to avoid tap breakage. Use a correctly sized tap drill for M4 x 0.7 threads per standard metric tap drill charts. Inspect the tap for wear or chipping regularly during production use and replace when thread quality degrades.
