The PEX Series is Dohre's carbide end mill series designed for carbon steel, alloy steel, cast iron, ordinary mold steel, and general steel machining up to HRC55.
This series includes square end mills, ball nose end mills, and corner radius end mills for different CNC machining needs. Whether the application requires flat surface machining, 3D contour finishing, shoulder milling, side-wall finishing, or stronger corner protection, the PEX Series provides stable cutting performance for finishing, semi-finishing, and light roughing under suitable machining conditions.
As a carbide end mill manufacturer, Dohre supports standard sizes, custom tool geometry, OEM production, and stable batch supply for steel machining applications.
PEX Series Carbide End Mills for Steel Machining
PEX Series carbide end mills are developed for stable machining of carbon steel, alloy steel, cast iron, ordinary mold steel, and general steel materials up to HRC55.
For production machining, the right end mill geometry directly affects cutting stability, surface finish, tool life, and dimensional consistency. A square end mill, ball nose end mill, and corner radius end mill are not used for the same machining area.
PEX Series provides three main cutter types for general steel machining:
Square end mills for flat surfaces, bottom machining, side milling, slotting, and step machining
Ball nose end mills for curved surfaces, 3D contours, mold profiles, and arc transitions
Corner radius end mills for shoulder milling, side-wall finishing, profile machining, and stronger corner protection
With stable carbide material, AlTiN nano coating, optimized rake angle, and controlled grinding quality, PEX Series end mills are suitable for machining factories that need reliable carbide cutting tools for daily steel part production.
Choose the Right PEX End Mill Type
The PEX Series includes three main carbide end mill types for carbon steel, alloy steel, cast iron, ordinary mold steel, and general steel machining up to HRC55. Choose the tool geometry according to the machining feature and surface requirement.
Best for flat surface machining, bottom finishing, slotting, side milling, shoulder milling, and step machining.
Choose this tool when the workpiece requires a flat bottom, straight side wall, clean step profile, or clear corner edge.
Best for curved surface finishing, 3D contour machining, mold profile finishing, arc surface machining, and smooth transition areas.
Choose this tool when the workpiece has curved surfaces, 3D profiles, mold contours, or freeform surfaces that require stable profile accuracy.
Best for shoulder milling, side-wall finishing, step machining, profile finishing, and applications requiring stronger corner protection.
Choose this tool when the application needs better edge strength, reduced corner chipping, and more stable side-wall or shoulder machining.
Key Features for HRC55 and Below Materials
PEX Series carbide end mills are designed for stable cutting performance in HRC55 and below steel materials.
Ultra-fine carbide with 10% cobalt content provides a balance of hardness, toughness, and wear resistance. This helps the cutting edge maintain stable performance during finishing, semi-finishing, and light roughing operations.
The AlTiN nano composite coating improves wear resistance and heat resistance during steel machining. It helps protect the cutting edge under higher cutting temperature and continuous cutting conditions.
The 6° positive rake angle helps reduce cutting resistance and supports smoother cutting. The 35° helix angle helps improve chip evacuation, reduce vibration, and maintain stable machining performance.
These design features make the PEX Series suitable for carbon steel, alloy steel, cast iron, ordinary mold steel, and general steel machining where stable batch quality and tool life are important.
