Value Collection MSC-04609830 Spiral Flute Tap 10-24 Unc

Product Description

The VALUE COLLECTION MSC-04609830 is a spiral flute tap designed to cut 10-24 UNC internal threads in blind holes requiring a bottoming chamfer. Built from high-speed steel with a bright/uncoated finish, it features a 45-degree helix angle and a fast flute style that evacuates chips efficiently during tapping operations. The H3 thread limit holds tight tolerances for 2B and 3B class-of-fit applications. At 2-3/8 inches overall length with 3 right-hand flutes, this tap suits precision threading work in machine shops, maintenance environments, and trade fabrication settings. Machinists and maintenance technicians are the primary users.

This tap is suited for threading blind holes in ferrous and non-ferrous metals where a full-depth thread close to the bottom of the hole is required. The bottoming chamfer leaves only 1 to 2 incomplete thread leads at the hole bottom, making it the right choice when thread engagement must start as close to the bottom as possible. It is commonly used in manual tapping operations as well as machine tapping setups where chip flow upward out of the hole is needed.

Key Features

• Bottoming chamfer for maximum thread depth in blind holes
• 45-degree helix angle with fast flute style for efficient chip evacuation
• High-speed steel construction for durability across ferrous and non-ferrous materials
• H3 thread limit for 2B/3B class-of-fit tolerance control
• Right-hand thread and right-hand flute direction for standard tapping operations
• Bright/uncoated finish suitable for use with cutting fluid

Compatibility

Designed as a standard 10-24 UNC bottoming tap compatible with manual tap handles and machine tapping chucks sized for this thread profile and shank diameter.

Installation Notes

This tap should be installed by a machinist or qualified maintenance technician familiar with tapping procedures. Secure the workpiece before tapping and use an appropriate cutting fluid to extend tool life and improve thread quality. For hand tapping, use a properly sized tap wrench and back off periodically to break chips. Inspect the tap for wear or chipping before each use to avoid thread damage or tap breakage.
