Value Collection JY63328587 Spiral Point Tap 5/8-11 Unc

Product Description

The VALUE COLLECTION JY63328587 is a spiral point tap designed for cutting 5/8-11 UNC internal threads in through-hole applications. Manufactured from high speed steel (HSS) with a bright uncoated finish, this plug-chamfer tap drives chips forward ahead of the cutting edge, making it well suited for production tapping in through holes. The H11 thread limit indicates a slightly oversize tap ground to produce threads at the upper tolerance range, accommodating plating or coating allowances. At 0.0050 inches oversize, it is appropriate where a controlled fit is needed after post-process treatment. This tap runs right-hand thread direction with 3 flutes and does not have coolant-through capability.

This tap is used in machine shop, maintenance, and manufacturing environments where 5/8-11 UNC through-hole threads are required. It is suitable for use in drill presses, CNC machining centers, and tapping heads operating at appropriate speeds for HSS tooling. Typical materials tapped include mild steel, aluminum, and similar machinable metals. It is installed and operated by machinists, tool-and-die makers, and maintenance technicians performing threading operations in fabrication or repair work.

Key Features

• Spiral point design pushes chips forward, optimized for through-hole tapping
• 5/8-11 UNC thread form, right-hand direction
• H11 thread limit with 0.0050 inches oversize for post-process plating or coating applications
• High speed steel construction for durability across common machinable metals
• Bright uncoated finish suitable for general-purpose tapping operations
• 3-flute configuration for chip clearance and cutting efficiency

Compatibility

Designed as an OEM-style replacement or standard tooling option for any application requiring a 5/8-11 UNC plug-chamfer spiral point tap with H11 thread limit and HSS construction.

Installation Notes

This tap should be installed in a compatible tap holder, collet, or tapping head rated for the shank size before use. Ensure the workpiece is securely fixtured and that the correct cutting fluid is applied for the material being tapped. Machinists should verify spindle speed and feed rate are appropriate for HSS tooling and the workpiece material before starting the threading operation. Inspect the tap for wear or damage before each use and replace when cutting performance degrades.
