Hertel K011216AS Spiral Point Tap 8-36 Unf Hss

Product Description

The HERTEL K011216AS is a spiral point tap designed for cutting internal threads in through-hole applications. Built from high-speed steel with a bright uncoated finish, this plug chamfer tap drives chips forward ahead of the cutting edge, keeping the flutes clear during machine tapping operations. It cuts 8-36 UNF threads with a right-hand helix and carries a H3 thread limit for consistent tolerance control. With 2 flutes and a 0.75-inch thread length, this tap suits production and maintenance threading tasks where chip evacuation and thread accuracy are the primary requirements. Machinists, maintenance technicians, and tool-and-die workers are the typical users.

This tap is suited for threading through-holes in ferrous and non-ferrous metals in both production shop and maintenance repair environments. The 8-36 UNF thread form is common in precision assemblies, instrumentation, and fine-threaded fastener applications where a finer pitch is required than the UNC equivalent. The plug chamfer allows the tap to start easily in a pre-drilled hole while maintaining cutting efficiency over the full thread length. Coolant-through capability is not available on this model, making it appropriate for hand or machine tapping with applied cutting fluid.

Key Features

• Spiral point geometry pushes chips forward, reducing clogging in through-hole threading
• High-speed steel construction provides durability across a range of workpiece materials
• Plug chamfer for easy hole entry and consistent thread engagement
• H3 thread limit ensures repeatable tolerance control in precision threading applications
• Right-hand thread direction compatible with standard tapping equipment and toolholders
• Bright uncoated finish suitable for use with cutting oils and water-soluble fluids

Compatibility

Designed as an OEM-style replacement or direct-use spiral point tap for 8-36 UNF through-hole threading operations in standard tapping chucks, CNC rigid tapping holders, and hand tap wrenches accepting this shank size.

Installation Notes

This tap is installed and used by machinists and maintenance technicians using standard tapping equipment. Always pre-drill with the correct tap drill size for 8-36 UNF before threading. Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Inspect the tap for wear or chipping before each use and replace if cutting edges show damage.
