  • Function/capability:
    • For sectioning hard samples, e.g.
      • Decalcified or undecalcified, embedded or unembedded bone, with or without implants
      • Teeth with or without implants
      • Mineralogical samples, ceramics and porcelain
      • Glass-fibre reinforced plastics
    • Internal-hole saw (280 μm thin) is diamond coated and rotates horizontally at a speed of approximately 600 rpm. An annular triple frame ensures outstanding stability
    • The saw's small thickness of 280 μm ensures a relatively little material loss
    • The specimen is drawn towards the saw by a spring which can be adjusted according to the different degree of specimen hardness
    • A built-in water cooling prevents overheating of the sample and caries the saw dust away
