Value Collection MSC-04476479 Straight Flute Tap

Product Description

The VALUE COLLECTION MSC-04476479 is a straight flute bottoming tap designed for cutting 11/16-16 UNS right-hand internal threads in through-holes and blind holes that require threading close to the bottom. Manufactured from high-speed steel with a bright, uncoated finish, this tap delivers reliable performance across a range of metals and materials commonly encountered in machining and maintenance operations. With 4 flutes and an H3 thread limit, it maintains consistent dimensional accuracy and chip clearance during hand or machine tapping operations.

This tap is suited for production and maintenance machining environments where 11/16-16 UNS threads are required. The bottoming chamfer style makes it the preferred choice when threads must extend to the bottom of a blind hole after a taper or plug tap has established the thread. It is commonly used by machinists, tool-and-die tradespeople, and maintenance technicians working on mechanical assemblies, fixtures, and repair applications.

Key Features

• Bottoming chamfer for threading to the base of blind holes
• 4 straight flutes provide efficient chip evacuation in through and blind-hole applications
• High-speed steel construction for durability across ferrous and non-ferrous materials
• H3 thread limit ensures controlled fit tolerance for standard UNS thread classes
• Bright, uncoated finish suitable for general-purpose tapping with cutting fluids
• Right-hand thread direction for standard tapping operations

Compatibility

Designed as a standard replacement or service tap for machining applications requiring 11/16-16 UNS internal right-hand threads.

Installation Notes

This tap should be installed in a compatible tap wrench, tap handle, or CNC/manual tapping machine with proper chuck collet sizing for the shank diameter. Always apply an appropriate cutting fluid for the workpiece material to reduce heat and extend tool life. Secure the workpiece firmly before tapping to prevent movement. Back the tap out periodically to clear chips, especially in deeper blind holes, to avoid tool breakage.
