Hertel K010330AS85 Thread Forming Tap 6-32 Unc

Product Description

The HERTEL K010330AS85 is a thread forming tap designed for cutting 6-32 UNC internal threads in through-hole applications. Unlike cutting taps, thread forming taps displace material rather than cut it, producing stronger threads with no chips to clear. This tap is manufactured from high-speed steel and finished with a TiCN coating that increases surface hardness and extends tool life in ferrous and non-ferrous materials. The plug chamfer with 3 to 5 chamfered threads makes it suited for through-hole threading where the tap can run fully through the workpiece. Overall length is 2 inches with a thread length of 0.6875 inches and a right-hand thread direction.

This tap is used in machine shops, maintenance facilities, and light manufacturing environments where 6-32 UNC fastener threads are required. Common applications include threading holes in thin sheet metal, aluminum housings, and electronic enclosures. It fits standard tap holders and handles compatible with the 0.1410-inch shank diameter. The H3 thread limit designation ensures consistent fit with standard 6-32 UNC fasteners across typical production tolerances. Installation is performed on drill presses, CNC machining centers, or tapping machines running at appropriate speeds for the workpiece material.

Key Features

• Thread forming design displaces material to produce chip-free, stronger threads
• TiCN coating improves wear resistance and extends tool life
• High-speed steel construction handles a wide range of workpiece materials
• Plug chamfer with 3 to 5 chamfered threads optimized for through-hole threading
• H3 thread limit provides consistent fit with standard 6-32 UNC fasteners
• Right-hand thread direction for use with standard tapping equipment

Compatibility

Designed for through-hole threading of 6-32 UNC internal threads. Compatible with standard tap holders and tapping chucks accepting a 0.1410-inch shank diameter.

Installation Notes

Thread forming taps require a properly sized forming tap drill hole, which differs from a standard cut tap drill size - consult a forming tap drill chart for the correct pilot hole diameter before use. Secure the workpiece fully before tapping and apply appropriate tapping fluid for the material being threaded. Use a torque-limiting tap holder where possible to prevent tap breakage. Follow applicable shop safety procedures when operating tapping equipment.
