The MIRACLE WSTAR DRILL series features a “wavy blade†that combines a concave cutting edge with a convex cutting edge to increase the sharpness and sharpness of the cutting edge. In order to improve the discharge performance of the chips, the grooves are formed by a small R portion which can cut the chips smaller and a large R portion which can be smoothly discharged. In addition, rigidity and positional accuracy are improved by reducing the taper angle and using a grinding process (reducing the center thickness to reduce the machining of the cutting resistance).
The newly added 20 new products include two models with L/D (machining depth/machining diameter) of 3 and 5. The coolant is supplied from the inside.
