Hertel K1001191464 Spiral Point Tap 8-32 Unc Hss

Product Description

The HERTEL K1001191464 is a spiral point tap designed for cutting internal threads in through-hole applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it cuts 8-32 UNC threads using a 2-flute, plug chamfer geometry. The spiral point design pushes chips forward ahead of the cutting zone, making it well suited for through-hole tapping where chip evacuation is critical. The H7 thread limit provides the tolerance control required for standard fastener fits. Machinists and maintenance technicians working on light-duty assemblies, electrical panels, and metal fabrication applications will find this tap a reliable production-grade option.

This tap is used in through-hole tapping operations on ferrous and non-ferrous metals where an 8-32 UNC thread is required. It is commonly applied in manufacturing, MRO maintenance, and field repair work involving sheet metal enclosures, equipment housings, and machine components. The right-hand thread direction and plug chamfer make it appropriate for use in CNC tapping operations as well as manual tapping with a standard tap wrench. Coolant-through capability is not included in this design.

Key Features

• 8-32 UNC thread size for standard fastener compatibility
• Spiral point geometry pushes chips forward for clean through-hole tapping
• 2-flute configuration balances chip room with cutting stability
• Plug chamfer provides a gradual lead-in for general-purpose tapping
• H7 thread limit for consistent tolerance control on standard fits
• High-speed steel construction handles a broad range of workpiece materials

Compatibility

Designed as a general-purpose replacement or production tap for any application requiring an 8-32 UNC, H7 thread limit, right-hand spiral point tap in high-speed steel.

Installation Notes

This tap is installed by machinists and maintenance technicians using a standard tap wrench, tapping head, or CNC rigid tapping setup. Ensure the workpiece is securely fixtured and the pilot hole diameter matches the recommended 8-32 drill size before tapping. Apply a suitable cutting fluid to extend tool life and improve thread quality. Inspect the tap for wear or chipping between uses and replace if thread quality degrades.
