Hertel K008202AS Spiral Point Tap 8-32 Unc Hss Plug

Product Description

The HERTEL K008202AS is a spiral point tap designed for cutting internal threads in through-hole applications. It features an 8-32 UNC thread form with a plug chamfer, making it suitable for starting a tap in a hole that has been drilled to the correct size. Manufactured from high-speed steel with a bright uncoated finish, this tap carries an H1 thread limit, meaning it produces threads at the low end of tolerance for close-fitting fastener assemblies. The 2-flute spiral point geometry pushes chips forward ahead of the tap, reducing clogging in through-hole work. The shank diameter measures 0.1680 inches and the thread length is 0.75 inches.

This tap is used in general machining, maintenance, and repair work where 8-32 UNC threads are required in through-hole configurations. Common applications include light fabrication, electrical panel work, instrumentation enclosures, and fixture assembly. The right-hand thread direction is standard for the vast majority of fastener applications. Coolant-through capability is not included, making this tap appropriate for manual or low-speed machine tapping in softer materials such as aluminum, mild steel, and plastics.

Key Features

• 8-32 UNC thread form with plug chamfer for through-hole tapping
• 2-flute spiral point design pushes chips forward to reduce clogging
• High-speed steel construction for durability across a range of workpiece materials
• H1 thread limit for close-tolerance thread production
• Bright uncoated finish suitable for use with cutting fluids
• Right-hand thread direction, standard fitment for most assembly work

Compatibility

Designed as a standard replacement or stock tap for 8-32 UNC through-hole tapping operations. Compatible with standard tap wrenches, T-handle holders, and tapping heads sized for the 0.1680-inch shank diameter.

Installation Notes

This tap is installed and driven by a licensed machinist or qualified maintenance technician using a tap wrench or machine tapping fixture. Always drill the correct tap drill size for 8-32 UNC before threading. Apply appropriate cutting fluid for the workpiece material to extend tap life and reduce the risk of breakage. Never reverse a spiral point tap at high speed, and back off periodically to clear chips when working in deeper holes.
