purpose-made and selected wolfram vanadium steel, shafts and drill tips manufactured from one-piece blanks, shaft ø 2.35 mm, l (total) = 44 mm
The purposeful and sturdy construction of the tungsten vanadium steel twist drills produces an optimally exact concentricity without sacrificing elasticity. Its high degree of hardness guarantees a long service life! The drills can be used for working on steel, non-ferrous metals, plastic, circuit board as well as softwoods and hardwoods. When working on soft material about 8,000 revolutions of rotary speed should be employed, for hard materials about 3,000.
