WhizCut of Sweden AB has developed a new and unique back-turning insert for its insert tooling system for automatic lathes.

The insert has two cutting edges, a 12° positive cutting rake and a chip former that will steer the chip away from the work piece. The special design of the cutting edge allows the insert to have contact with the work piece only along the straight cutting edge and a short part of the wiper edge. The radial pressure is hereby considerably lower than with conventional back turning tools.

The combination of positive cutting edge, low cutting force, low radial pressure and short length of contact has resulted in better roundness of the turned diameter, easier to keep small tolerances, better surface finish, fewer adjustments during the tool-life of the cutting edge and considerably longer tool-life.
