Hertel K008140AS Straight Flute Tap 6-32 Unc Hss

Product Description

The HERTEL K008140AS is a straight flute tap designed to cut 6-32 UNC internal threads in through-holes and blind holes where chip control is managed by the operator. Built from high-speed steel with a bright uncoated finish, this plug-chamfer tap features 2 flutes and a right-hand thread direction. The overall length is 2 inches. The H2 thread limit provides a controlled tolerance class 3B fit, making it suited for applications where thread accuracy and close tolerances are required. Licensed machinists, toolroom technicians, and maintenance mechanics rely on this type of tap for precision threading in steel, aluminum, and similar materials.

This tap is appropriate for general-purpose threading operations in production and maintenance environments. The plug chamfer, with its moderate lead, works for both through-holes and sufficiently deep blind holes where the chamfer can start the thread before the straight flutes continue the cut. The 6-32 UNC thread size is common in electrical panel work, instrument enclosures, and light mechanical assemblies. The straight flute geometry is best suited for harder, shorter-chipping materials where chip evacuation out of the hole is not a primary concern.

Key Features

• 6-32 UNC thread size with right-hand thread direction
• Plug chamfer for versatile use in through-holes and deep blind holes
• 2 straight flutes for use in shorter-chipping materials
• High-speed steel construction for durability across common tap materials
• H2 thread limit ensures class 3B fit tolerance compliance
• Bright uncoated finish — no coating offset required for thread calculations

Compatibility

Designed as a standard straight flute tap for use in tapping 6-32 UNC threaded holes in typical shop, production, and maintenance threading applications.

Installation Notes

This tap should be installed in a tap handle, tapping head, or CNC tapping collet rated for the shank size. Always ensure the workpiece is securely clamped and the tap is started square to the hole to prevent tap breakage and cross-threading. Use an appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Do not force a tap that has stopped cutting — back off to clear chips before continuing.
