Value Collection JY4849105 Straight Flute Tap 1-10 Uns

Product Description

The VALUE COLLECTION JY4849105 is a straight flute tap designed for cutting 1-10 UNS internal threads in through-hole and blind-hole applications. Built from high-speed steel with a bright, uncoated finish, this tap delivers reliable thread-cutting performance across a range of workpiece materials. The plug chamfer configuration — featuring a gradual lead of several threads — allows for smooth thread initiation in both through and moderately deep blind holes. With 4 flutes and an H4 thread limit, this tap is suited for production and maintenance threading operations requiring consistent 3B class of fit tolerances.

This tap is appropriate for use in machine shop environments, maintenance and repair operations, and heavy industrial applications where large-diameter unified special (UNS) threads are required. The 1-10 UNS thread form is common in heavy mechanical assemblies and custom fastener applications. Right-hand thread direction makes it compatible with standard tapping machines, CNC machining centers, and manual tap handles equipped for 1-inch tooling. The bright finish is suitable for use with standard cutting fluids or tapping compounds.

Key Features

• 1-10 UNS thread form with 3B class of fit for precision internal threading
• High-speed steel construction for durability across ferrous and non-ferrous materials
• Plug chamfer for balanced performance in through-holes and moderate blind holes
• H4 thread limit for consistent fit in tolerance-controlled assemblies
• 4 straight flutes for chip clearance and cutting stability
• Bright, uncoated finish compatible with standard tapping lubricants and coolants

Compatibility

Designed as a standard replacement or production tap for applications requiring 1-10 UNS right-hand internal threads with a 3B class of fit.

Installation Notes

This tap should be installed and operated by a qualified machinist familiar with large-diameter tapping procedures. Secure the workpiece firmly before tapping and ensure the tap is properly aligned with the pilot hole to prevent tap breakage or thread distortion. Use an appropriate cutting fluid or tapping compound for the workpiece material to extend tool life and improve thread quality. Follow all applicable machine shop safety practices when operating tapping equipment.
