Accupro T2690703 Spiral Point Tap 3/4-10 4 Flutes Plug

Product Description

The ACCUPRO T2690703 is a spiral point plug tap designed for threading 3/4-10 UNC holes in ferrous and non-ferrous metals, including titanium. Made from 3% vanadium high-speed steel with a bright uncoated finish, it delivers consistent thread quality in through-hole applications. The spiral point geometry pushes chips forward ahead of the tap, reducing clogging in production and maintenance environments. With 4 flutes, an H3 thread limit, and right-hand thread direction, this tap suits machinists, tool-and-die shops, and maintenance mechanics who need reliable thread cutting in demanding materials.

This tap is used in through-hole tapping operations where chip evacuation is a priority. The plug chamfer allows the tap to start easily and cuts threads progressively to full depth. At 4.25 inches overall length, it fits standard tap handles and CNC tapping heads. The 3/4-10 UNC thread specification makes it appropriate for heavy structural fastening applications in manufacturing, fabrication, and industrial maintenance settings. Coolant-through is not supported, making it suitable for conventional tapping with applied cutting fluid.

Key Features

• 3/4-10 UNC thread size with H3 thread limit for consistent fit tolerances
• 4-flute spiral point design pushes chips forward for clean through-hole threading
• Plug chamfer for easy starting and progressive thread cutting
• 3% vanadium high-speed steel construction for cutting titanium and other tough materials
• Bright uncoated finish — ready for use with standard cutting fluids
• Right-hand thread direction, standard for most tapping applications

Compatibility

Designed for use in standard 3/4-10 UNC through-hole tapping applications across manual tap handles and machine tapping setups where coolant-through tooling is not required.

Installation Notes

This tap should be installed by a qualified machinist or maintenance mechanic familiar with tapping procedures and tooling specifications. Ensure the workpiece is securely fixtured and that the tap is properly aligned with the drilled hole before starting. Apply an appropriate cutting fluid for the workpiece material, particularly when working with titanium. Inspect the tap for wear or damage before each use to avoid thread damage or tap breakage.
