Hertel K008015AS Straight Flute Tap 1-64 Unc Hss

Product Description

The HERTEL K008015AS is a straight flute plug tap designed for threading 1-64 UNC holes in light-duty and precision machining applications. Built from high-speed steel with a bright, uncoated finish, this tap delivers reliable thread-cutting performance in ferrous and non-ferrous materials. It features 2 straight flutes and a plug chamfer with a 2B class of fit and an H2 thread limit, making it well suited for producing threads within standard tolerance ranges. Overall length is 1.6875 inches with a thread length of 0.375 inches. Licensed machinists and toolroom technicians are the primary users for this style of tap.

This tap is used in manual hand-tapping operations and machine tapping setups where straight-flute geometry is preferred, typically in through-holes or shallow blind holes in softer materials. Its 1-64 UNC thread size makes it appropriate for precision instrument work, small fastener threads, and light mechanical assemblies. The right-hand thread direction follows standard convention for the vast majority of threading operations in these industries. Coolant-through capability is not included, making it best suited for conventional tapping with applied cutting fluid.

Key Features

• 1-64 UNC thread size with right-hand thread direction
• 2 straight flutes with plug chamfer for general-purpose through-hole and shallow blind-hole tapping
• 2B class of fit with H2 thread limit for standard tolerance threads
• High-speed steel construction for durability in ferrous and non-ferrous materials
• Bright, uncoated finish suitable for use with standard cutting fluids
• Compact overall length of 1.6875 inches for use in tight workspaces

Compatibility

Designed as an OEM-style replacement or standard toolroom tap for applications requiring 1-64 UNC right-hand threads in manual or machine tapping operations.

Installation Notes

This tap should be installed in a tap wrench or appropriate machine tap holder before use. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill size for 1-64 UNC threads before beginning. Apply a suitable cutting fluid to extend tool life and improve thread finish. Follow OSHA and shop safety guidelines when operating any rotating cutting tool.
