Walter-prototyp 7305284 Spiral Point Tap 5/8-11 Unc

Product Description

The WALTER-PROTOTYP 7305284 is a spiral point tap designed for through-hole threading in a wide range of metals. Built from High-Speed Steel-E (HSS-E) and finished with a Titanium Nitride (TiN) coating, this tap delivers extended tool life in demanding production environments. It features a 5/8-11 UNC thread form, 4 flutes, and a plug chamfer, which provides a moderate lead-in suitable for most through-hole applications. The right-hand thread direction and 2B class of fit make it a standard choice for general-purpose fastener holes in steel, stainless steel, cast iron, and non-ferrous metals. Licensed machinists and tool-and-die technicians working in CNC or manual tapping operations will find this tap well-suited to high-volume production work.

This tap is intended for through-hole threading applications in both production shop and job-shop environments. It performs across a broad material range including steel, stainless steel, cast iron, and non-ferrous metals. The plug chamfer style requires clearance on the exit side of the workpiece, making it appropriate for through-bores rather than blind holes. The TC216 series is engineered for consistent thread quality and dimensional accuracy in repetitive CNC tapping cycles as well as manual operations.

Key Features

• 5/8-11 UNC thread form with 2B class of fit for standard fastener hole tolerances
• HSS-E base material provides enhanced toughness and wear resistance over standard HSS
• TiN coating reduces friction and extends tool life in ferrous and non-ferrous materials
• 4-flute spiral point design pushes chips forward through the hole, reducing clogging in through-hole applications
• Plug chamfer offers a reliable lead-in for most through-hole production scenarios
• Right-hand thread direction compatible with standard CNC and manual tapping setups
• No coolant-through requirement simplifies tooling setup

Compatibility

Designed for through-hole tapping of 5/8-11 UNC threads in steel, stainless steel, cast iron, and non-ferrous metals. Part of the WALTER-PROTOTYP TC216 series.

Installation Notes

Install in a compatible tap holder sized for the 12 mm shank diameter before use. Verify spindle speed and feed rate are set per the material being tapped prior to engaging the workpiece. Ensure the workpiece is securely fixtured and the hole is drilled to the correct tap drill diameter for a 5/8-11 UNC thread before tapping. Because this is a plug chamfer spiral point tap, use only in through-bores with sufficient chip clearance on the exit side.
