FS Tool’s O-Flutes feature a mirror finish and a specialized geometry. The aluminum cutting O-flutes are DLC coated to minimize the recutting of chips and to prevent rewelding. The prepped cutting edge is designed to provide long-lasting tool life. The DLC coating offers superior performance, says the company. Other features include high tolerance polished shanks and a reengineered tip for greater strength in plunging operations. Metric and imperial sizes are available.
