Hertel K008016AS Spiral Point Tap 1-64 Unc Hss

Product Description

The HERTEL K008016AS is a spiral point tap designed for threading operations in machine and production environments. Built from high speed steel with a bright finish, it cuts 1-64 UNC threads in a right-hand direction using a plug chamfer profile and 2-flute geometry. The spiral point pushes chips forward ahead of the cutting zone, making it well-suited for through-hole tapping where chip evacuation is critical. The H1 thread limit holds tight tolerances for consistent 3B class fits. This tap is a standard choice for machinists and tool-and-die professionals working with small-diameter fastener threads.

This tap is used in production tapping, repair work, and prototype machining where 1-64 UNC threads are required. The plug chamfer makes it appropriate for through-hole applications where the tap can advance fully through the workpiece. The 2-flute design provides a balance of chip flow and thread form accuracy at this fine pitch. It is suited for use in soft to medium-hardness materials commonly threaded with high speed steel tooling. Manual tapping and machine tapping setups are both within its intended operating range.

Key Features

• 1-64 UNC thread size for fine-pitch small-diameter applications
• Spiral point geometry pushes chips forward, improving through-hole performance
• High speed steel construction provides durability across a range of workpiece materials
• Plug chamfer profile suits standard through-hole tapping operations
• H1 thread limit maintains consistent 3B class of fit tolerances
• Bright finish with no coating, allowing direct visual inspection of tool condition

Compatibility

Designed as an OEM-style replacement or standard production tap for through-hole tapping applications requiring a 1-64 UNC, 3B class fit thread in right-hand orientation.

Installation Notes

This tap is installed and operated by machinists or tool-and-die technicians using standard tapping equipment or hand tap wrenches. Secure the workpiece and ensure proper alignment before starting the cut to avoid tap breakage at this small diameter. Use an appropriate cutting fluid for the workpiece material to extend tool life and maintain thread quality. Follow shop safety practices and machine guarding procedures when tapping under power.
