End mill for machining aluminum materials
Many customers have told us that ordinary end mills frequently stick when machining aluminum, and the accumulation of chips affects the accuracy, so they always change the tools. LIZHOU editor suggests that coated end mills are not recommended for aluminum materials, because some coatings contain aluminum elements. Therefore, it is better to choose uncoated end mills when selecting end mills for machining aluminum materials.
