Value Collection MSC-04466132 Straight Flute Tap 5/8-11

Product Description

The VALUE COLLECTION MSC-04466132 is a straight flute tap designed to cut 5/8-11 UNC internal threads in through-hole and open-blind-hole applications. Built from high-speed steel with a bright, uncoated finish, this tap features a taper chamfer that progressively engages the workpiece to reduce starting torque and improve thread alignment. With 4 flutes and an H2 thread limit, it delivers consistent dimensional accuracy suitable for standard tolerance threading work. Overall length is 3.8125 inches and thread length is 1.8125 inches. Machinists, tool-and-die makers, and maintenance technicians are the primary users of this tool.

This tap is suited for general-purpose threading in ferrous and non-ferrous materials where straight flute geometry is appropriate — typically softer steels, aluminum, brass, and similar machinable metals. The taper chamfer style makes it well suited for starting threads by hand or under machine power in through-holes or in holes where chip clearance is not a constraint. It handles right-hand thread cutting in standard UNC 5/8-11 applications found in manufacturing, repair, and maintenance environments.

Key Features

• 5/8-11 UNC thread size with right-hand thread direction
• Taper chamfer for progressive thread engagement and easier starting
• 4 straight flutes for chip clearance in through-hole and soft-material applications
• High-speed steel construction for durability across a range of machinable metals
• H2 thread limit for standard dimensional tolerance control
• Bright, uncoated finish — no coating buildup, suitable for use with cutting fluids

Compatibility

Designed as a standard straight flute tap for use in manual tap handles, T-handle wrenches, and compatible tapping machines that accept 5/8-11 UNC tooling.

Installation Notes

Installation is performed by qualified machinists or maintenance technicians using appropriate tap handles or tapping attachments. Ensure the workpiece is securely fixtured and the tap is started perpendicular to the hole to prevent cross-threading or breakage. Apply a suitable cutting fluid for the material being tapped to extend tool life and improve thread finish. Reverse the tap periodically when hand-tapping to break chips and reduce the risk of tap seizure.
