A detailed buying guide: how to choose an SDS plus drill bit.
SDS bits and chisels are for rotary and demolition hammers, for drilling and chiselling concrete, brick and stone. This section covers SDS-plus and SDS-max bits and flat, pointed and wide chisels.
SDS-plus is for light rotary hammers up to 4 kg, SDS-max for heavy hammers and breakers. Read how to choose an SDS max drill bit.
Two-cutter bits are cheaper, while four-cutter (cross-tip) bits are faster and do not jam on rebar.
Pointed chisels break concrete, flat ones remove tile, while wide and U-shaped ones strip plaster and cut channels.
Overall length includes the shank; for hole depth look at the working length. Read how to choose drill-bit diameter and length.
Grease the SDS shank before each fitting and wear glasses and ear protection. Read how to use a rotary hammer safely.
Sharpen chisels without overheating and replace worn bits.
At ToolsArmenia you can choose SDS Drill Bits and Chisels by shank, number of cutters, diameter and length.
