One of the notable advantages of solid carbide burs(https://www.carbidebursfactory.com/product/carbide-rotary-burs-metric/solid-carbide-burs/) over welded burrs lies in their construction. They are manufactured from a single piece of carbide material, which provides good structural integrity and eliminates potential weak points commonly found at weld joints. Welded burrs, on the other hand, join a carbide or steel cutting head to a separate shank, creating a junction susceptible to stress fractures or separation under high rotational speeds or heavy cutting loads.
