What is the maximum number of teeth that can be missing from a 12 tooth carbide blade before it is considered out of service?

When evaluating the condition of a 12 tooth carbide blade, the standard for determining when it should be taken out of service is based on the maximum number of missing teeth. According to safety protocols and equipment maintenance guidelines, a blade can function effectively only if it has most of its teeth intact.

In the case of a 12 tooth carbide blade, losing up to 3 teeth is within acceptable limits, as this ensures that enough cutting surfaces remain for effective operation and minimizes the risk of equipment failure or hazardous situations. Once 4 teeth are missing, the blade is considered significantly compromised, which can lead to uneven cutting, increased wear on the remaining teeth, and potential safety hazards for the user.

Thus, when 3 teeth are missing, although the blade may still be operational, it is nearing its threshold for safe use. This understanding is crucial for proper maintenance and safety practices in operations involving cutting tools.
