Rotech Investigate Fractured Drill Bit For Specialist Medical Supplier

The fractured drill bit failure was investigated to prevent the likelihood of future failures.

All the customer’s products are developed, designed and tested to meet internationally required quality standards.

Hardness Testing was carried out in accordance with BS EN ISO 6507-1 2005 and was carried out to observe the materials ability to resist deformation, followed by examinations using the Scanning Electron Microscope (SEM) to reveal any material defects and damage.

This can also show evidence of fatigue fracture mechanisms and indicate the wear and area of damage.

The evidence, gathered from the testing carried out, indicated the drill bit failure was due to tensile overload and the wear of the fracture surface and damage to the drill edges suggested adverse operational conditions.
