Cylindrical carbide end mill with two square cutting ends and gold TiN coating

YG-1 Tool Company

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

SKU CH-A8FF-QB73V

Carbide double-end square mill with 30° helix and TiN finish for general-purpose machining of steels and non-ferrous metals

  • TiN coating extends tool life in abrasive materials
  • 30° helix angle improves chip evacuation during milling
  • Double-end design provides two cutting ends per tool
  • Four-flute geometry delivers smooth finish on steel and stainless
  • Center-cutting capability allows plunging and slotting operations

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.

Questions about this item

Will this 30° helix carbide end mill work in an older manual mill with standard 1/2 inch tool holders?

The 1/2 inch shank diameter fits standard tool holders on manual and CNC mills, and the 30° helix with TiN finish is designed for general-purpose cutting in mild steel, stainless and non-ferrous metals.

How can I verify the E5024 is cutting correctly after installing it in the spindle?

Check for smooth chip evacuation and a clean square profile on the workpiece; the four-flute center-cutting design should produce consistent finishes in mild steel and stainless without chatter when speeds and feeds are set for carbide.

Does the E5024 come with any collets, tool holders or coating touch-up kits, or must I buy those separately?

The product is supplied as the carbide end mill only; collets, tool holders and any maintenance items are separate purchases.
