Value Collection MSC-04485199 Straight Flute Tap 9/16-18

Product Description

The VALUE COLLECTION MSC-04485199 is a straight flute bottoming tap designed to cut internal threads in drilled holes where full thread depth close to the bottom is required. Made from high-speed steel with a bright, uncoated finish, this tap produces a 9/16-18 UNF right-hand thread with 4 flutes for efficient chip evacuation in most common materials. The bottoming chamfer allows threading to within a few threads of a blind hole bottom. With an overall length of 3.375 inches and a thread length of 1.656 inches, it fits standard tap handles and machine tapping setups used in maintenance, toolroom, and production environments.

This tap is suited for threading operations in ferrous and non-ferrous metals, plastics, and similar workpiece materials. The 9/16-18 UNF thread specification is common in hydraulic fittings, fastener applications, and precision mechanical assemblies. Machinists, tool and die makers, and maintenance technicians will find this tap appropriate for both hand tapping and light machine tapping applications where a fine-pitch unified thread is required at or near a blind hole bottom.

Key Features

• Bottoming chamfer allows threading to the bottom of blind holes
• 9/16-18 UNF fine-pitch thread form for precision fastener and fitting applications
• 4-flute design aids chip clearance during cutting
• High-speed steel construction provides durability across a range of workpiece materials
• H5 thread limit for close-tolerance thread production
• Right-hand thread direction, standard configuration

Compatibility

Designed as a standard replacement or working tap for any setup requiring a 9/16-18 UNF bottoming tap with an H5 thread limit. Fits standard tap wrenches and collet-style tapping heads sized for the 9/16-inch tap body diameter.

Installation Notes

Tapping should be performed by a qualified machinist or maintenance technician using properly sized tap handles or a tapping head set to the correct speed for the workpiece material. Ensure the workpiece is securely fixtured and the tap is started square to the hole before applying cutting pressure. Use appropriate cutting fluid for the material being tapped to extend tap life and improve thread finish. Do not force a bottoming tap beyond its designed depth or use it to start a thread from an undrilled or unchamfered hole.
