SDC01,SDC02 specially designed for very dense and abrasive ductile iron-an Iron-carbon-silicon alloy commonly 

used to make water and sewage pipes.

SDC03,Vacuum  brazed  diamond  segment  and  laser welded  designed  for  most  building  materials  under  emergency.

Advantage:Vacuum  brazed segment with  highest quality diamond to  keep the aggressive cutting.

Laser welded type to keep the core hardness and tension to avoid wobble problem when cutting.

Small holes and slots design near segment help smoothly cutting and saw blade air-cooling.

SDC04 Vacuum brazed carbide segments designed for rescue situation including bulle-proof glass,PVC,plastic,

metal,roof,steel  studs  and  move.

Advantage:Carbide parcal size 6-8mm,good for synthetic material,reinforce concrete,and can tearing off most materials.

Noise reduce core design will reduce noise in cutting.
