demolition breaker is small version of jackhammer

This 24.9 lb tool is called a demolition breaker. It is a 1600-watt demolition tool that is sort of like a smaller version of a jackhammer. It impacts up to 2200 times per minute at a volume of 80 cubic inches per minute. For the operator’s comfort, it has a cushioned side handle and it has AVR (active vibration reduction) that reduces vibration by 60 percent.

Accessories for the demolition breaker:

A flat chisel has a polygon design and is self-sharpening. The clay spade is used for digging up hard clay. The flex chisel is for removing linoleum or ceramic tile.

When using this tool to break up material, start with a pointed tip chisel. Set the tool 4" from the edge of the material you are breaking up. Once the edge of the material has been broken up, use the flat chisel.

A tamping tool is used with the demolition breaker for tamping down loose gravel. The flat plate on the tamping bit is vibrated up and down by the demolition tool to tamp the gravel or dirt. To put a bit into the tool, push down the locking collar, insert the chisel, and release the collar.

Use safety glasses and hearing protection when operating this tool.
