Hertel K011048AS Spiral Point Tap 8-36 Unf 2 Flute Hss

Product Description

The HERTEL K011048AS is a spiral point tap designed for cutting 8-36 UNF internal threads in through-hole applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this plug chamfer tap is engineered for right-hand threading in metals and other machinable materials. The spiral point geometry pushes chips forward ahead of the cutting zone, making it well suited for through-hole tapping where chip evacuation is a priority. With 2 flutes and an H4 thread limit, it produces threads within a controlled tolerance range appropriate for standard UNF fastener fits. Thread length is 0.75 inches.

This tap is used in machine shop, production, and maintenance environments where 8-36 UNF threads are required in through-hole workpieces. The plug chamfer provides a gradual thread lead-in, making it practical for both machine tapping and hand tapping operations. It is commonly used by machinists, tool and die makers, and maintenance technicians working with small-diameter fastener holes in metal components. The H4 thread limit is appropriate for standard class 2B and some class 3B thread fits.

Key Features

• Spiral point geometry pushes chips forward for clean through-hole tapping
• High-speed steel construction provides good wear resistance in ferrous and non-ferrous materials
• Plug chamfer with 2 flutes offers a balance of lead-in and cutting efficiency
• H4 thread limit ensures controlled tolerance for standard UNF fastener fits
• Bright, uncoated finish — no coating buildup to affect thread tolerance
• Right-hand thread direction for standard tapping operations

Compatibility

Designed for cutting 8-36 UNF right-hand internal threads in through-hole applications. Fits standard tap holders and tapping heads accepting this shank size.

Installation Notes

This tap should be installed in a compatible tap holder, tapping head, or tap wrench rated for small-diameter taps. Always ensure the workpiece is securely fixtured before tapping. Use appropriate cutting fluid for the material being tapped to extend tool life and improve thread finish. Inspect the tap for wear or chipping before each use, and never force a tap that has stopped threading freely.
