◆Quality high speed steel ensures the bits super hard, sharp and cutting effectively with impressive cutting performance in metal, plastic, and wood etc with long tool life.
◆Precision treatment makes drills durable toughness, withstands heavy duty operation, resists corrosion and lubricates the drill bits better for cutting smoothly.
◆Fully grinding processing makes the surface of drill bit smoother, the friction can be reduced and the cutting speed is faster.
◆Process: fully-ground.
◆Material: HSS or HSS-cobalt.
◆Application material: steel, cast iron or other soft metal.
◆Surface treatment: white, black, tin-coated.
◆Diameter size:2.0-13
