Super Dumbbell – the ultimate punching knife

with replaceable precision cutting blades

Super Dumbbell has a spring type ejector, is equipped with 5 sets of precision spare blades and therefore represents a set of six punching knives in total. It is ideally designed for manual and pneumatic presses.

Excellent price-performance-ratio

“6 knives for the price of 1”

Replaceable precision cutting blades

  • Japanese carbon steel: ultra-hard – extremely sharp – maximum cut resistance
  • Easy replacement
  • No regrinding
  • No downtime
  • Cutting blade symmetry prevents concave cross-sectional geometry (Fig. 1)
  • Extremely smooth cut surfaces of test specimens (Fig. 2)
  • Always available separately

 

Fig. 1: Cutting blade symmetry

Conventional cutting blades are asymmetrical to the cutting edge and produce a concave crosssection geometry which leads to considerable measuring errors. Symmetrical precision cutting blades produce a rectangular cross-section geometry and thus high-precision test specimens for reliable and reproducible test results.
