Hertel K008061AS25 Spiral Point Tap 3-48 Unc Tin

Product Description

The HERTEL K008061AS25 is a spiral point tap designed for threading 3-48 UNC holes in metalworking applications. It features a plug chamfer and two flutes, which push chips forward through the hole ahead of the cutting edge. The tap is manufactured from high-speed steel (HSS) with a titanium nitride (TiN) coating that increases surface hardness and reduces friction during cutting. It carries an H2 thread limit and a 2B class of fit, making it suitable for standard fastener clearances. The right-hand thread direction and 0.5-inch thread length make it a straightforward choice for through-hole tapping in light-gauge work.

This tap is used in production and maintenance machining environments where small-diameter threads are required. The 3-48 UNC designation is common in precision assemblies, instrument panels, and light-duty fastener applications. It is appropriate for use in drill presses, CNC machining centers, and hand-tapping setups. Machinists and tool-and-die technicians working in job shops, maintenance facilities, or production floors will encounter this size when threading steel, aluminum, brass, and similar machinable materials.

Key Features

• Spiral point geometry pushes chips forward, reducing clogging in through-hole operations
• TiN coating improves wear resistance and extends tool life compared to uncoated HSS
• H2 thread limit provides accurate fit for standard 2B class of fit requirements
• Right-hand, plug chamfer profile suitable for starting threads in pre-drilled holes
• HSS construction offers toughness for both hand and machine tapping
• 0.1410-inch shank diameter fits standard tap holders and chucks for this size range

Compatibility

Designed as a direct-use spiral point tap for 3-48 UNC through-hole threading operations. Compatible with standard tap holders and chucks accepting a 0.1410-inch shank diameter.

Installation Notes

This tap is installed and used by machinists and maintenance technicians following standard tapping procedures. Always ensure the workpiece is securely fixtured and that the tap is properly aligned before beginning the threading operation. Use an appropriate cutting fluid for the workpiece material to reduce heat buildup and extend tap life. Inspect the tap for chipping or wear before each use, as small-diameter taps are susceptible to breakage under misalignment or excessive torque.
