Hertel K008157AS Spiral Point Tap 6-32 Unc Hss

Product Description

The HERTEL K008157AS is a spiral point plug tap designed for cutting 6-32 UNC threads in through-hole applications. Built from high-speed steel with a bright uncoated finish, it produces clean internal threads by pushing chips forward ahead of the cutting action, making it well suited for production and repair threading work. The tap features a 2-flute design, H3 thread limit, and a 2B class of fit, delivering consistent thread tolerance across standard fastener assemblies. Overall length is 2.0 inches. Right-hand cutting direction. Weight is 0.15 pounds.

This tap is used in metalworking and maintenance applications where 6-32 UNC through-hole threads are required. Typical installation scenarios include threading sheet metal, light structural components, and electrical enclosure hardware. The plug chamfer style provides a gradual lead-in with moderate starting ease, making it appropriate for both manual tapping and light-duty machine tapping operations. It is commonly used by machinists, HVAC fabricators, electricians, and maintenance technicians working with small-diameter machine screw threads.

Key Features

• Spiral point geometry pushes chips forward, reducing chip packing in through-hole threading
• 6-32 UNC thread form with 2B class of fit for standard fastener compatibility
• H3 thread limit for consistent tolerance in production threading
• High-speed steel construction provides durability across steel, aluminum, and similar workpiece materials
• Plug chamfer offers balanced starting ease and cutting efficiency
• Bright uncoated finish suitable for general-purpose threading without specialty lubricant requirements

Compatibility

Designed as a standard 6-32 UNC spiral point plug tap compatible with manual tap handles and machine tapping setups that accept standard straight-shank taps of this size class.

Installation Notes

This tap is installed by machinists and maintenance technicians using a tap wrench, tapping head, or CNC tapping attachment rated for the shank size. Ensure the workpiece is properly secured and the pilot hole is drilled to the correct tap drill size for 6-32 UNC threads before starting. Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Do not force the tap if resistance increases unexpectedly, as breakage in small-diameter taps is difficult to reverse.
