High slope recedes away from the cutting edge. Minimizes chip clogging. Improved sharpness with large rake angle. Chipbreaker dot extended to the cutting edge. Divides the chips into smaller pieces. Low cutting force design with a small chipbreaker step. Good chip control in small depths of cut due to the breaker dot projecting to the cutting edge. ap (mm) Wide range of accetpable chip control is achieved due to advanced chip breaker design.
