Rotech Investigate Fractured Drill Bit For Specialist Medical Supplier
Rotech’s Metallurgy Test Lab in Wednesbury has been working with a specialist medical supplier that develops surgical implant systems, to investigate a fractured stainless steel drill bit and identify the reason for failure.
The Rotech team conducted a Hardness Testing visual investigation in accordance with to BS EN ISO 6507-1 2005 and SEM (Scanning Electron Microscope) Fractography/Microscopical Investigation. The visual inspection on the drill bit fracture revealed surface staining and damaged edges.
Calcium deposits (bone) were found on the fractured drill bit although it had been thoroughly sterilised after use. This was identified by the SEM/EDAX (Energy Dispersive Spectroscopy).
