Hertel K008263AS Straight Flute Tap 10-32 Unf Hss

Product Description

The HERTEL K008263AS is a straight flute tap designed for cutting internal 10-32 UNF threads in a wide range of materials. Built from high-speed steel with a bright, uncoated finish, this tap delivers reliable thread formation in ferrous and non-ferrous metals under typical shop and field conditions. It features a plug chamfer, 3 flutes, and a 3B class of fit with an H2 thread limit, making it suitable for standard tolerance internal thread applications. Overall length is 2.375 inches, and the right-hand thread configuration matches the vast majority of standard fastener installations. This tool is used by machinists, maintenance technicians, and trade professionals performing repair threading or production tapping operations.

This tap is intended for use in hand tapping or low-speed machine tapping applications where straight flute geometry is appropriate, such as threading through-holes or short blind holes in materials that produce broken chips. The 10-32 UNF thread size is commonly encountered in electrical enclosures, instrumentation panels, HVAC controls, and light mechanical assemblies. The plug chamfer allows the tap to start easily in a pre-drilled hole and is the most common chamfer style for general-purpose threading work across residential, commercial, and industrial maintenance tasks.

Key Features

• 10-32 UNF straight flute tap with 3 flutes for chip clearance in through-hole and short blind-hole applications
• Plug chamfer style for easy starting and general-purpose use
• High-speed steel construction provides hardness and wear resistance across common workpiece materials
• Bright, uncoated finish for standard applications without special coating requirements
• 3B class of fit and H2 thread limit ensure standard tolerance threads compatible with commercial fasteners
• Right-hand thread direction matches standard fastener orientation

Compatibility

Designed as a standard 10-32 UNF plug tap suitable for use in hand tap handles and low-speed tapping heads configured for the appropriate shank size. Verify pre-drill diameter against the recommended tap drill size for 10-32 UNF threads before use.

Installation Notes

This tap is installed and used by machinists and maintenance technicians performing internal thread cutting operations. Always secure the workpiece and use a calibrated tap handle or tapping head to maintain axial alignment. Apply an appropriate cutting fluid to the tap and workpiece before and during the tapping operation to reduce friction and extend tool life. Back the tap out periodically to break and clear chips, especially in deeper holes.
