Chipstream Insert : Takes the minimum power requirement. Ideal for use where the turned length is such that the coils of swarf produced do not constitute a problem or a health hazard to the operator. Chipbreaker Insert : Requires slightly more power, but breaks the swarf up into short lengths over a wide range of speeds and feed for most materials. Pos. Insert : The plain rake face with chipdeflector is often more effective on very small depths of cut especially on awkward materials such as swedish iron. Alternative Radii : Alternative radii are available on inserts Ex stock or to order. Price and delivery on application.
