Butterfield CAE2279A Left Hand 2 Inch End Mill

Butterfield CAE2279A is a 2" diameter left-hand end mill with a 6" length of cut and a 10" overall length. This high-speed steel (HSS) cutter uses a 6-flute geometry designed for efficient chip evacuation and a smoother finish on larger-diameter workpieces. The left-hand cutting direction is specified by the CAE2279A designation, which can affect chip flow and torque in setups that require reverse cutting action. With a 6" LOC and 10" OAL, the tool provides reach for pockets and deeper features while maintaining rigidity in typical milling applications. The CAE2279A model identifies Butterfield’s LH end mill within its lineup, making it a suitable choice when a large-diameter LH tool is required for heavy milling tasks, slotting, or general milling on machines that accept standard 2" cutters. Use the end mill with appropriate speeds and feeds for the material being machined, and confirm compatibility with your holder and spindle before use.
