X-MILL 430L Solid Carbide End Mill 4.0 mm, 4-Flute, 25 mm Cut, 75 mm OAL, Cylindrical Shank

For machinists who demand clean, precise slotting and profiling in tough materials, the X-MILL 430L solid carbide end mill delivers a sharp, uncoated cutting edge that bites into steel, stainless, cast iron, and non-ferrous alloys without chatter. Unlike general-purpose mills with fewer flutes, its 4-flute geometry balances chip evacuation and surface finish, making it a workhorse for both roughing and semi-finishing passes in CNC and manual setups.

Highlights

• Solid carbide (VHM) construction for high rigidity and wear resistance
• 4-flute design for improved surface finish and higher feed rates
• Cylindrical shank with h6 tolerance for secure, concentric clamping
• Sharp square corner for precise 90° shoulders and slot walls
• Uncoated cutting edge ideal for general-purpose milling across multiple material groups

In daily use

Set up this end mill in a collet chuck or hydraulic holder and you'll notice immediate stability during side milling and slotting operations. The 4.0 mm cutting diameter handles fine details, while the 25 mm cutting length allows deeper pockets without deflection. Because the tool is uncoated, it's also a smart choice for shops that prefer to apply their own coatings or for applications where coating adhesion could be a concern. The right-hand cut direction suits standard spindle rotation, and the DIN 6527-compatible geometry means it drops into existing tool libraries with minimal adjustment.
