Value Collection JY4763140 Spiral Point Tap 7/16-14 Unc

Product Description

The VALUE COLLECTION JY4763140 is a spiral point tap designed for cutting 7/16-14 UNC right-hand threads in through-hole applications. The spiral point geometry pushes chips forward ahead of the cutting edge, keeping the flutes clear and enabling continuous thread cutting without chip pack. Built from high speed steel (HSS) with a bright uncoated finish, this tap operates at standard cutting speeds for ferrous and non-ferrous materials. The plug chamfer distributes the cutting load across the first several threads, making it well suited for through-hole tapping on manual machines and CNC equipment alike. Thread limit is H11, and the tap is ground 0.0050 inches oversize to compensate for material spring-back.

This tap is used in machine shops, maintenance facilities, and production environments where 7/16-14 UNC through-holes are required in steel, cast iron, aluminum, brass, and similar materials. The 3-flute design provides a balance of strength and chip clearance, making it appropriate for both hand tapping and machine tapping operations. Plug chamfer style is the standard choice when tapping holes that pass completely through a workpiece. Coolant-through is not supported on this tap, so conventional flood or brush-applied cutting fluid is recommended during use.

Key Features

• Spiral point geometry pushes chips forward, reducing chip packing in through-hole applications
• 7/16-14 UNC thread form, right-hand cutting direction
• H11 thread limit, ground 0.0050 inches oversize for accurate fit after spring-back
• High speed steel construction for durability across a wide range of workpiece materials
• Plug chamfer distributes cutting load over multiple lead threads for smooth entry
• Bright uncoated finish — compatible with a broad range of cutting fluids without coating interaction

Compatibility

Designed as an OEM-style replacement or standard tooling solution for any application requiring 7/16-14 UNC right-hand internal threads in through-hole configurations on manual lathes, drill presses, tapping machines, and CNC machining centers.

Installation Notes

This tap should be installed by a qualified machinist or tooling technician following standard tapping procedures. Ensure the workpiece is securely fixtured and the tap is properly aligned with the pilot hole before engaging the cut. Apply a suitable cutting fluid for the workpiece material throughout the operation to extend tap life and improve thread finish. Do not exceed the tap's rated cutting speed for the material being tapped, and reverse the tap periodically during hand tapping to break and clear chips.
