PQYTOOL Cermet End Mill 4 Flutes D4(d)3*L50*FL7.5 For Milling Machine
$7.29 USD
~~A Cermet end mill is a type of milling cutter made from a composite material called cermet, which is a combination of ceramic and metal. Advantages of cermet tools: high wear resistance and superior surface finish capability.
High Wear Resistance: Superior to traditional cemented carbide in many applications, especially at higher temperatures.
Excellent Surface Finish: Cermet tools have a low affinity for metal, which reduces the formation of a built-up edge (BUE) and leads to very smooth, shiny surface finishes.
Good Chemical Stability: Less interaction with the workpiece material, which minimizes adhesive wear.
Finishing Operations: They excel in finishing and semi-finishing of various materials, particularly in applications where surface quality and close tolerances are critical. (less suitable for heavy roughing or severely interrupted cuts.)
Conditions: Best used at high cutting speeds with light to medium feed rates and depths of cut, typically without coolant (dry cutting or compressed air) to avoid thermal shock.
