Value Collection JY4844205 Straight Flute Tap 1/2-24 Uns

Product Description

The VALUE COLLECTION JY4844205 is a straight flute bottoming tap designed for cutting right-hand internal threads to the 1/2-24 UNS thread standard. Built from high-speed steel with a bright, uncoated finish, this tap delivers reliable performance in production and maintenance threading applications. The bottoming chamfer allows threading close to the bottom of blind holes where plug or taper taps cannot reach. With 4 flutes and an H3 thread limit, this tap holds close dimensional tolerances suited to 3B class of fit assemblies. Overall length is 3-3/8 inches. Machinists, toolmakers, and maintenance technicians rely on this configuration for precision thread forming in ferrous and non-ferrous materials.

This tap is suited for machine shop, maintenance, repair, and overhaul environments where blind-hole threading to a 1/2-24 UNS specification is required. The 3B class of fit makes it appropriate for general-purpose mechanical assemblies where a standard tolerance thread engagement is specified. It is commonly used in manual tapping operations as well as with tapping heads and drill press setups. The bright uncoated finish works well across a range of materials when used with appropriate cutting fluid.

Key Features

• Bottoming chamfer enables threading to the bottom of blind holes
• 1/2-24 UNS right-hand thread form, 3B class of fit
• H3 thread limit for consistent dimensional accuracy
• 4 straight flutes for chip clearance in through and blind holes
• High-speed steel construction for durability across common workpiece materials
• Bright uncoated finish compatible with standard cutting fluids

Compatibility

Designed as an OEM-style replacement or standard tooling option for any application requiring a 1/2-24 UNS bottoming tap with a 3B class of fit and H3 thread limit.

Installation Notes

This tap is installed by machinists or maintenance technicians using a tap wrench, tapping head, or drill press with tapping attachment. Always ensure the workpiece is securely fixtured and the tap is properly aligned with the pilot hole before beginning the threading operation. Use appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Back off the tap periodically to break chips and prevent tap breakage in deeper blind holes.
