| Features | 1.Center drill bits can be used to make conical holes for a lathe center in order to make a starting point for a standard twist drill, designed to prevent the twist drill from walking, as well as for producing center holds in components or work pieces with require machining between centers. 2.Available for all Kinds of Materials: Metal, Alloy, Copper, Iron, Wood, Aluminum, and so on. 3.Durable and Resistance: Center drill bit is made of HSS high speed steel, with extremely sharp blade, low consumption and durable with impact resistance, wear resistance. 4.center drills have flutes and cutting points on both ends. this allows the user with the ability to reverse the drill and utilize both ends. 5.Out micro-grain carbide substrate offers excellent hardness, wear resistance and high strength. These tools can provide increased feeds and enhanced tool life in application that have right set-ups. 6.60 degree countersink angle fits all standard centers 7.High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance |
