Value Collection MSC-04609855 Spiral Flute Tap 10-32 Unf

Product Description

The VALUE COLLECTION MSC-04609855 is a spiral flute tap designed for cutting internal threads in blind holes and through holes where chip evacuation is critical. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap cuts a 10-32 UNF right-hand thread to a 2B class of fit, which meets standard tolerance requirements for most threaded fastener applications. The bottoming chamfer allows threading close to the bottom of a blind hole. With a 45-degree helix angle and fast flute style, chips are pulled up and out of the hole during the tapping operation, reducing the risk of chip packing and tap breakage. Overall length is 2.375 inches.

This tap is suited for use in machine shops, maintenance and repair operations, and light manufacturing environments. It is commonly used with a tapping head, CNC machining center, or manual tap wrench to produce 10-32 UNF threads in materials such as aluminum, mild steel, and plastics. The 3-flute spiral design performs well in materials that produce long, stringy chips. Machinists and toolmakers working on small-diameter threaded holes in production or repair settings will find this tap appropriate for that work.

Key Features

• 10-32 UNF thread size with right-hand thread direction
• Bottoming chamfer for threading close to the base of blind holes
• 3-flute spiral design with 45-degree helix angle for efficient chip evacuation
• High-speed steel construction for durability across common workpiece materials
• Bright, uncoated finish — no coating buildup that could affect thread tolerance
• H3 thread limit for consistent 2B class of fit compliance

Compatibility

Designed as a standard replacement or stock tap for applications requiring 10-32 UNF internal threads. Fits standard tap holders and tapping chucks sized for this shank diameter.

Installation Notes

Install in a properly sized tap holder or collet before use. Ensure the workpiece is securely fixtured and the pilot hole diameter is drilled to the correct tap drill size for a 10-32 UNF thread before tapping. Apply appropriate cutting fluid or tapping compound for the workpiece material to extend tool life and improve thread quality. Inspect the tap for wear or chipping before each use and replace if cutting edges show damage.
