Kennametal 5416937 Spiral Point Tap 1/2-20 Unf Hss-e

Product Description

The KENNAMETAL 5416937 is a spiral point tap designed for through-hole threading operations in metalworking and machining environments. Built from High-Speed Steel-E (HSS-E) in the KSP39 material grade and finished with an oxide coating, this tap delivers reliable performance in demanding cutting conditions. It features a 1/2-20 UNF thread size with a right-hand thread direction, 3 flutes, and a plug chamfer for smooth thread entry. With an overall length of 3.375 inches and a thread length of 0.9375 inches, it fits standard tap holders used in machine shop and production environments. This tap is engineered for machinists and tooling specialists working with ferrous and cast materials.

The 5416937 is suited for through-hole threading applications in steel, stainless steel, and cast iron. The spiral point geometry pushes chips forward ahead of the cutting action, making it well-matched for through-hole work on CNC machining centers, drill presses, and tapping machines in both production and job-shop settings. The H7 thread limit ensures consistent fit tolerances across threaded holes in precision assemblies.

Key Features

• Spiral point geometry pushes chips ahead for clean through-hole threading
• HSS-E construction with oxide coating for improved wear resistance and heat tolerance
• Plug chamfer provides gradual thread entry and controlled cutting force
• H7 thread limit for consistent tolerance in precision threaded holes
• Right-hand, 1/2-20 UNF thread form for standard unified fine-thread applications
• Compatible with steel, stainless steel, and cast iron workpieces

Compatibility

Designed for through-hole threading in steel, stainless steel, and cast iron. Fits standard 1/2-inch tap holders and collet systems used on CNC machining centers, drill presses, and tapping arms. Part of the KENNAMETAL T820 series.

Installation Notes

This tap should be installed and operated by qualified machinists or tooling technicians familiar with tapping speeds, feeds, and cutting fluid requirements for the workpiece material. Power down or de-energize the machine before changing tooling. Use appropriate cutting fluid or coolant for the material being threaded to maximize tool life and thread quality. Follow machine manufacturer torque and speed recommendations for the tap diameter and material application.
