3-Flute Carbide Roughing End Mill | BF2055 & BC2055 for Aluminum Milling

BB Roughing End Mill

☆Usually 35° can meet the rough machining with large margin or relatively soft material machining.

☆45° can be processed relatively difficult to machine materials, but the cutting volume is slightly lower.

☆Normally, 30/35° helix angle is used for material processing, and 45° helix angle is recommended for stainless steel.
