YG-1 Tool Company Carbide End Mill E5024 Square Double End 30° helix TiN

Application Scope

This carbide end mill is a general-purpose cutting tool designed for milling operations in mild steels, soft to medium-hard steels, stainless steels and non-ferrous metals. The double-end configuration provides two usable cutting ends, effectively extending tool life for cost-conscious machine shops. It is not intended for hardened tool steels or exotic alloys that demand specialised geometries or coatings beyond standard TiN.

Capacity and Headroom

The 30-degree helix angle and four-flute design offer a balance of chip evacuation and finish quality across the listed material groups. Centre-cutting capability allows for plunge cuts and slotting in addition to side milling. The tool reaches its practical limit when machining materials significantly harder than the specified range or when operations require higher helix angles for aggressive aluminium removal rates.

Critical Specification

The TiN finish is the single attribute that determines suitability for your application, as it provides increased hardness and heat resistance over uncoated carbide for the stated material groups. If your workflow involves sustained high-temperature cutting in titanium or high-temperature alloys, a different coating such as TiAlN or AlTiN would be necessary. Buyers needing coolant-through capability or a different shank standard should look elsewhere.
