Fresa de topo de metal duro 8,0 mm 19/63 Z4 HA8 TS 440N MASTERMILL 440N

For machinists who demand clean cuts and long tool life in general-purpose steel work, the MASTERMILL 440N solid carbide end mill stands apart from coated alternatives by relying on a precision-ground bright finish and a robust 4-flute geometry. The 8.0 mm cutting diameter and 19 mm cutting length make it a practical choice for slotting, profiling, and shoulder milling in steels up to approximately 440 N/mm² tensile strength. Built to DIN 6527 general-purpose standards, this tool combines a 30° helix angle with a cylindrical HA shank for secure clamping and reliable chip evacuation.

Highlights

• Solid carbide (VHM) construction for high rigidity and wear resistance
• 4-flute square-end design for balanced material removal and good surface finish
• Uncoated bright finish ideal for non-ferrous and low-alloy steel applications
• 30° helix angle reduces cutting forces and improves chip flow
• DIN 6527 compliant dimensions: 8.0 mm diameter, 19 mm flute length, 63 mm overall length
• Cylindrical HA shank (8.0 mm) fits standard collets and hydraulic holders

In daily use

Set up this end mill in a rigid holder, keep runout below 0.01 mm, and it will handle full slotting cuts up to 0.5×D and profiling passes with ease. The bright finish prevents built-up edge when machining mild steel, while the 4-flute configuration offers a good compromise between chip space and tool strength. For best results, use coolant or air blast to clear chips from deep pockets.
