Value Collection MSC-04534137 Spiral Point Tap 1/2-13 Unc

Product Description

The VALUE COLLECTION MSC-04534137 is a spiral point tap designed for threading 1/2-13 UNC through-holes in a wide range of metalworking and fabrication applications. Built from high speed steel (HSS) with a bright, uncoated finish, this plug chamfer tap drives chips forward ahead of the cut, making it well suited for through-hole tapping operations. The H2 thread limit provides controlled tolerance for standard fit assemblies. With 3 flutes and right-hand thread direction, this tap delivers consistent thread form across ferrous and non-ferrous materials in production and maintenance environments.

This tap is used in machine shop, maintenance, and general metalworking settings where 1/2-13 UNC threads are required in through-hole configurations. The plug chamfer, which features a moderate lead-in, handles the majority of production tapping work where the tap can pass fully through the workpiece. It is installed by machinists, toolmakers, and maintenance mechanics using manual tap handles, CNC machining centers, or drill presses equipped with tapping attachments.

Key Features

• 1/2-13 UNC thread size with right-hand thread direction
• Plug chamfer for through-hole tapping in general production use
• 3-flute spiral point geometry pushes chips forward, clearing the cut path
• H2 thread limit for controlled tolerance and standard fit assemblies
• High speed steel construction for durability across ferrous and non-ferrous materials
• Bright, uncoated finish — no coolant-through feature, suited for standard cutting fluids

Compatibility

Designed as a standard replacement or production tap for applications requiring 1/2-13 UNC internal threads in through-hole workpieces. Compatible with standard 1/2-13 tap holders, machine tap adapters, and manual T-handle tap wrenches.

Installation Notes

Installation is performed by machinists or maintenance mechanics using appropriate tap holders or tapping heads. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill size for 1/2-13 UNC before tapping. Apply a suitable cutting fluid or tapping compound to extend tap life and improve thread finish. Never force a tap; back off periodically to clear chips and prevent breakage.
