Hammer drill bit made of high quality alloy steel 40Cr (metal construction part) and tungsten carbide tip YG8C
(drilling tip) with tip's hardness 88°HRc (+/-2°) and point angle 130°.
Special shape of soldered tungsten carbide tip ensures quick and central drilling.
SDS-plus shank with patented multi-channel KVS spiral with symetric shape on total length, guarantees
stable and dynamic characteristics when drilling (reduction of vibration), what significantly enlarges
drilling capacity as a result of quick chips removal from the hole and extends drill's working life.
Heat treatment and surface sandblasting reduces drill's wear and enlarges durability on inside stresses
which appear while using.
Suitable for industrial purposes when using drills and hammer drills "class 2kg" with SDS-plus
or double-channel clamping for drilling in masonry, concrete, granite and other natural stones.
According to DIN-8035.
