Hertel K008966AS Tap Set 6-32 Unc 3 Flute Hss Bright

Product Description

The HERTEL K008966AS is a 3-piece tap set designed for cutting 6-32 UNC internal threads in metal workpieces. Built from high speed steel (HSS) with a bright finish, this set delivers consistent thread cutting performance in production and maintenance applications. The overall length is 2 inches, and the set covers both 2B and 3B classes of fit, giving technicians the flexibility to meet standard tolerance requirements in a single kit. Three flutes provide efficient chip evacuation during through-hole and blind-hole tapping operations.

This tap set is suited for machine shops, maintenance and repair operations, and field service environments where 6-32 UNC threaded fastener holes are required. The H2 thread limit designation indicates a ground thread tap appropriate for use with standard 6-32 UNC fastener systems. Machinists, millwrights, and maintenance technicians working on electrical panels, enclosures, small assemblies, and light mechanical components will find this set applicable to a wide range of tapping tasks.

Key Features

• Thread size: 6-32 UNC, covering both 2B and 3B class of fit
• High speed steel construction for durability across a range of workpiece materials
• 3-flute geometry promotes chip evacuation in through-hole and blind-hole applications
• H2 thread limit for consistent tolerance control
• Bright finish — no coating to alter tap geometry or add dimensional buildup
• Compact 2-inch overall length suits standard tap handles and machine spindles

Compatibility

Designed as a direct-use tap set for cutting 6-32 UNC internal threads. Compatible with standard tap handles, T-handle wrenches, and machine tapping heads configured for small-diameter straight-shank taps.

Installation Notes

Tapping operations should be performed by qualified machinists or maintenance technicians familiar with proper speeds, feeds, and cutting fluid selection for the workpiece material. Secure the workpiece fully before beginning and use a calibrated tap guide or machine spindle to maintain thread alignment. Start with the taper tap, progress to the plug tap, and finish with the bottoming tap when tapping blind holes to full depth. Inspect tapped threads with a 6-32 UNC go/no-go gauge after completion to verify class of fit.
