Add Oil Hole FLAT Drill for deep hole Realize 5D drilling with high efficiency. Wide Application of material Applicable from carbon steel, alloy steel and cast iron to stainless steel. Well balanced flute geometry realizing both rigidity and excellent evacuation Improve chip separation and evacuation. Inter-mediate double margin realizes highly accurate boring and controls oversize Hole enlargement is reduced and a wide range of work materials are supported AQUA Drill EX FLAT Oil-Hole - Applicable from carbon steel, alloy steel and cast iron to stainless steel. Amount of oversize is reduced due to a double margin and the shape of the negative rake blade tip. A cutting edge design that minimizes cutting resistance Sharp cutting edge that ensures a clean cut through carbon fiber Cutting resistance is minimized to help prevent CFRP delamination and exit burring Crystal diamond coating with increased crystallinity Newly developed crystal diamond coating offers improved wear resistance and a longer tool life, made possible by increasing the crystallinity CFRP machining comparison Tool life comparison Number of holes until delamination (0.5 mm) occurs Wear comparison Wear after 1,120 holes (NACHI) 350 holes (Competitor)
