The SDS MAX drill bit tip is made from a strong material such as tungsten to give it strength under extreme loads and fully hardened, giving high performance. 

SDS MAX is perfect for drilling or chiselling into hard materials due to the shank design and drill type. The grooves of the shank sit into the chuck securing it into position but still allowing the SDS drill bit to slide up and down as the drill hammers up and down

SDS MAX drills are specialized hammer drills and are made for drilling and chiselling into tough materials like Concrete, Granite, Rock, Stone, and Masonry

SDS MAX Bits are designed solely for use with MAX machines, they are not compatible with the smaller SDS Plus machines.
