How to Use
Use one cutting end in a rigid milling setup and keep the opposite end clear of the holder and workpiece. Select speeds, feeds, coolant and stepovers for the material; use an open or prepared entry if plunge cutting is not specified.
Double-end tools require adequate holder clearance and secure clamping. Do not use an unsupported direct plunge unless the setup and tool geometry permit it. Wear eye protection and use machine guarding. California Proposition 65 warning may apply.
