Hertel K033002AS Spiral Flute Tap 6-32 Unc Hss Oxide

Product Description

The HERTEL K033002AS is a spiral flute tap designed for cutting 6-32 UNC internal threads in a variety of ferrous and non-ferrous workpieces. Built from high-speed steel with an oxide coating, this tap delivers reliable wear resistance across production and maintenance threading applications. It features a plug chamfer for progressive thread engagement, a 45-degree helix angle for fast flute action, and a 2B class of fit for standard commercial thread tolerances. With an H3 thread limit, it holds tight dimensional consistency across repeated cuts. The 2-inch overall length fits standard tap holders and hand-tapping setups alike. Machinists, tool-and-die workers, and maintenance mechanics are the primary users.

This tap is suited for threading blind or through holes requiring 6-32 UNC threads in light-duty to medium-duty machining environments. The 3-flute spiral design evacuates chips upward and out of the hole, making it especially effective in through-hole applications and where chip packing is a concern. The right-hand flute direction and right-hand thread direction are the standard configuration for conventional 6-32 fastener applications. It is appropriate for manual tapping operations as well as low-speed machine tapping on drill presses and CNC equipment without coolant-through capability.

Key Features

• 6-32 UNC thread size with right-hand thread direction for standard fastener compatibility
• Plug chamfer provides progressive thread engagement suitable for through holes and blind holes with adequate depth
• 45-degree helix angle promotes fast chip evacuation and reduces torque buildup
• H3 thread limit ensures consistent 2B class of fit across production runs
• Oxide coating improves surface lubricity and provides basic corrosion resistance during storage and use
• High-speed steel construction withstands the heat and stress of repeated threading cycles

Compatibility

Designed as a direct-fit replacement or standard tooling selection for any tap holder, wrench, or machine spindle configured for 6-32 UNC spiral flute taps with standard shank dimensions for this size range.

Installation Notes

Threading operations should be performed by a qualified machinist or maintenance mechanic familiar with tap geometry and proper feeds and speeds for high-speed steel tooling. Secure the workpiece fully before tapping and ensure the correct tap drill size has been used for 6-32 UNC prior to starting the tap. Apply cutting fluid or tapping compound appropriate for the workpiece material to extend tool life and reduce the risk of tap breakage. This tap does not support coolant-through delivery, so external lubrication is required.
