HSS 3.3 MM DRILL BIT

Short Description:

1.  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.

2.  Precision treatment makes drills durable toughness, withstands heavy duty operation, resists corrosion and lubricates the drill bits better for cutting smoothly.

3.  Fully Grinding Processing makes the surface of drill bit smoother, the friction can be reduced and the cutting speed is faster.

4.  135°118° Split Point Design improves cutting speed while easy self-centering, prevent walking and skating across the workpiece surface.
