• The two flute end mills for aluminum have High Helix flute design making
them well suited for milling aluminum and other non-ferrous materials.
Special rake angles and low micro inch finishes on the primary clearance
angles and flute faces insure free cutting action, fine finishes and longer
tool life for both non-ferrous materials as well as harder alloys. These
tools are made from regular H.S.S.(M2), which is good for aluminum
