Introducing the head-changeable WIN-DRILL line with a unique cutting edge design that improves productivity as well as reduces the cost for small hole applications. The replaceable head design of the new WIN-DRILL products, which are available in 0.1 mm increments between 4.0-5.9 mm head diameters, eliminates the need for extra set-up time and increases productivity compared to the solid carbide drill option currently available. These features effectively make the WIN-DRILL family the innovative small-diameter hole machining solution.
