The carbide-tooth head and four-flute body ensure good grip on the material and efficient debris removal; the weight of around 2.244 kg goes with the greater body length.\u003c\/p\u003e\n\u003cp\u003eAn SDS-Max bit is a carbide-tipped bit for rotary hammers with an SDS-Max chuck, for large-diameter, deep holes in concrete and masonry.\u003c\/p\u003e\n\u003ch3\u003eWhat it is for\u003c\/h3\u003e\n\u003cp\u003eUsed for drilling reinforced concrete, in hammer or rotary hammer mode and for drilling solid and hollow masonry, clay brick and blocks.\u003c\/p\u003e\n\u003ch3\u003eHow to use it\u003c\/h3\u003e\n\u003cp\u003eClean and lightly grease the shank, insert it into the chuck until it locks and select hammer drilling. Drill with the hammer held in line with the hole, letting the machine's weight do the work without pushing, and withdraw the bit frequently to clear the dust.
