Value Collection MSC-04546412 Spiral Point Tap 11/16-11 Uns

Product Description

The VALUE COLLECTION MSC-04546412 is a spiral point tap designed for cutting internal threads in through-hole applications. Built from high speed steel with a bright uncoated finish, this tap uses a plug chamfer and three-flute spiral point geometry to push chips forward ahead of the cutting zone, reducing clogging and improving thread quality. The 11/16-11 UNS thread form and H3 thread limit make it suited for controlled-tolerance threading work in metalworking and machining operations. Licensed machinists and tool-room technicians are the primary users of this tool.

This tap is applied in through-hole threading jobs where chip evacuation is a priority. The spiral point design drives chips ahead of the tap rather than packing them behind, making it well suited for production drilling and tapping on CNC machining centers, drill presses, or manual tapping operations. The plug chamfer provides a gradual lead-in, distributing cutting load across several threads at entry. It covers the 11/16-11 UNS specification, a coarse-pitch unified national special thread form used in custom or non-standard fastener applications.

Key Features

• Spiral point geometry pushes chips forward for clean through-hole threading
• High speed steel construction provides wear resistance across a range of workpiece materials
• Plug chamfer with 3 to 5 thread lead-in distributes cutting load at entry
• H3 thread limit ensures controlled tolerance fit for standard fastener engagement
• Bright uncoated finish — compatible with standard cutting fluids and oils
• Right-hand thread direction for standard clockwise tapping

Compatibility

Designed for through-hole tapping of 11/16-11 UNS internal threads in machining and fabrication applications where a plug chamfer and spiral point geometry are required.

Installation Notes

This tap is installed and operated by machinists using standard tapping equipment including CNC machining centers, drill presses with tapping attachments, or manual tap handles. Always secure the workpiece and use appropriate cutting fluid for the material being tapped. Inspect the tap for wear or chipping before use and do not force a dull tap, as breakage in the bore may result. Follow applicable shop safety and tooling procedures for rotating cutting tools.
