Selection of the appropriate hydraulic breaker chisel :

Chisel Type	Characteristics
Wedge Chisel	Excellent split power, Good penetration,Torque will have a direct role in the rock
Flat/ Blunt Chisel	The energy provided by a large surface, The best crushing effect, No torque occurs at a fixed pin
Moil Point/ Cone Chisel	Provide a very marvellous  penetration when through point, Split power being transmitted around, No reverse
