Hertel K008466AS Spiral Point Tap 3/8-24 Unf Plug Hss

Product Description

The HERTEL K008466AS is a spiral point tap designed for threading 3/8-24 UNF holes in a wide range of materials. Spiral point geometry pushes chips ahead of the cutting edge and out of the hole, reducing clogging and heat buildup in through-hole tapping applications. Built from high-speed steel with a bright uncoated finish, this tap delivers consistent thread quality in ferrous and non-ferrous metals. The plug chamfer provides a standard lead-in suitable for most general-purpose through-hole threading work. Right-hand cut, H2 thread limit, and 3 flutes make this a versatile choice for production and maintenance machining operations.

This tap is suited for threading through-holes in machine shops, maintenance facilities, and manufacturing environments. The 3/8-24 UNF thread form is common in precision fastener applications across automotive, aerospace, and general industrial assembly. The plug chamfer requires a small starting pocket or through-hole clearance and is not intended for blind-hole work where a bottoming tap would be required. Machinists and tool-and-die technicians working on manual or CNC machines will find this tap appropriate for moderate-volume through-hole threading jobs.

Key Features

• Spiral point geometry pushes chips forward through the hole, reducing chip packing in through-hole applications
• High-speed steel construction provides good wear resistance across ferrous and non-ferrous workpiece materials
• Plug chamfer with 3-5 thread lead-in suits general-purpose through-hole tapping
• H2 thread limit maintains close tolerance fits for standard UNF fastener assemblies
• Bright uncoated finish compatible with a wide range of cutting fluids and tapping compounds
• Right-hand cut matches standard UNF fastener direction

Compatibility

Designed for cutting 3/8-24 UNF right-hand internal threads in through-hole applications on compatible manual and CNC machine tool setups.

Installation Notes

Always use appropriate cutting fluid or tapping compound for the workpiece material to extend tap life and improve thread finish. Ensure the tap is properly aligned with the drilled hole before engagement to avoid tap breakage. Secure the workpiece fully before threading operations. Follow ANSI B94.9 guidelines for tap drill size selection to maintain proper thread engagement percentage.
