What’s the difference between the bits used on a Rotary Pneumatic and standard impact hammer drill?
Rotary Pneumatic hammer drill bits are specially engineered to be able to withstand the high impact action generated with continuous use in professional applications. Rotary bits also have special fitment slots used for rapid bit changes. This fitment type is known as SDS which there are several forms available such as SDS, SDS PLUS and SDS MAX. Basically the difference is their increased duty rating and size of the associated bits.
