Hand sawing utilizes state of the art concrete cutting equipment which allows JPH to cut perfectly square inside corners and eliminate over cutting. These saws are powered by electric, hydraulic, gas and pneumatic motors. With cutting depths, up to 24 inches these tools can operate in spaces where similar depth cutting machines couldn’t possibly go.
Hand chain saws are utilized:
- when you can’t have over cuts on an opening
- Diamond chain saws allow perfectly square inside corner cuts
Over cutting is caused when using a 30″ circular blade to cut to full depth of 12″. In order to reach 12″ depth of cut a 30″ blade would have to travel 15″ past the surface of the opening go get 12″ penetration at the bottom.
