Value Collection MSC-04464145 Straight Flute Tap 1/2-13

Product Description

The VALUE COLLECTION MSC-04464145 is a straight flute tap designed for cutting 1/2-13 UNC internal threads in blind and through holes. Made from high-speed steel (HSS) with a bright/uncoated finish, this tap features a bottoming chamfer that allows threading close to the bottom of a blind hole. With 4 flutes and a right-hand thread direction, it is suited for general-purpose tapping in a machine shop or maintenance environment. The H2 thread limit ensures controlled tolerance for standard UNC thread fits. Overall length is 3.375 inches with a thread length of 1.656 inches.

This tap is used in machining, fabrication, and maintenance applications where 1/2-13 UNC threads are required in ferrous and non-ferrous materials. The bottoming chamfer makes it particularly useful when full thread depth is needed near the base of a blind hole, a common requirement in fixture building, equipment repair, and part fabrication. It is typically run in a drill press, CNC machining center, or tapping arm by machinists, toolmakers, and maintenance technicians.

Key Features

• Bottoming chamfer for threading to the bottom of blind holes
• High-speed steel construction for durability across a range of materials
• 4-flute design provides stability and chip control during tapping
• H2 thread limit for standard UNC tolerance fits
• Right-hand thread direction for standard tapping applications
• Bright/uncoated finish suitable for general-purpose use

Compatibility

Designed for cutting 1/2-13 UNC right-hand internal threads in standard tapping applications across machining, fabrication, and maintenance environments.

Installation Notes

This tap is installed by machinists and maintenance technicians using a tapping chuck, tap wrench, or CNC rigid tapping setup. Always ensure the workpiece is securely fixtured and the tap is properly aligned with the drilled hole before beginning. Use appropriate cutting fluid for the material being tapped to extend tool life and improve thread quality. For blind holes, use a bottoming tap after a taper or plug tap has started the thread, or begin with this tap carefully to avoid bottoming out under power.
