Value Collection JY63328306 Spiral Point Tap 9/16-12 Unc

Product Description

The VALUE COLLECTION JY63328306 is a spiral point tap designed for threading 9/16-12 UNC holes in a wide range of metals and industrial materials. Spiral point taps — sometimes called gun taps — push chips forward ahead of the cutting edge rather than backing them into the flute, making them well suited for through-hole threading operations. This tap features three flutes, a plug chamfer, and is manufactured from high speed steel with a bright uncoated finish. It carries an H3 thread limit, indicating a tolerance band appropriate for standard fit threaded connections. Licensed machinists, maintenance mechanics, and trade professionals who produce threaded fastener locations in steel, aluminum, and similar materials will find this tap a reliable production choice.

This tap is intended for through-hole threading applications in production and maintenance machining environments. The plug chamfer — typically four to five threads of lead — provides a balance between easy starting and thread engagement, making it practical for both CNC tapping operations and hand tapping with a tap wrench. The H3 thread limit suits standard 2B tolerance class fits commonly specified in general mechanical assemblies. Right-hand cutting direction aligns with standard right-hand threaded fasteners.

Key Features

• 9/16-12 UNC thread form for standard unified coarse pitch threading
• Three-flute spiral point design pushes chips forward for clean through-hole threading
• Plug chamfer for easy starting and reliable thread engagement
• High speed steel construction for durability across a broad range of workpiece materials
• H3 thread limit for standard 2B tolerance class fits
• Right-hand cutting direction; no coolant-through feature required for typical applications

Compatibility

Designed as an OEM-style replacement or direct-use spiral point tap for any application requiring a 9/16-12 UNC right-hand thread in a through-hole configuration.

Installation Notes

This tap is installed by machinists and maintenance mechanics using a tap wrench, tapping head, or CNC spindle. Ensure the workpiece is securely fixtured and the correct tap drill size for 9/16-12 UNC is used prior to tapping. Apply appropriate cutting fluid to extend tap life and improve thread quality. Follow shop safety practices and de-energize any powered equipment before performing manual tapping operations on machinery.
