Concrete saw

Blade choice and diamond saw blades
– Consider the concrete/asphalt type (reinforced, stone aggregate, curing time)
– Determine if wet or dry cutting is needed
– Decide between faster cutting or longer lifespan
– Take into account the power output of the concrete saw
– Choose a diamond saw blade with the appropriate design and specifications
– Diamond saw blades are commonly used on concrete saws
– Ideal for cutting concrete, asphalt, stone, etc.
– Often laser welded
– Require cooling to prolong their lifespan and reduce dust
– Can be selected based on cutting speed or lifespan needs

Dust control and safety measures
– Use wet cutting with adequate water supply
– Prefer diamond saw blades over abrasive blades
– Equip the concrete saw with a local exhaust ventilation system
– Always wear personal protective equipment (PPE) while operating
– Address other risks such as noise, flying debris, hand-arm vibration, manual handling, electricity, and refueling

Types of concrete saws
– Small hand-held saws
– Chop-saw models
– Big walk-behind saws
– Other styles available
– Powered by gasoline, hydraulic or pneumatic pressure, or an electric motor

Friction and cooling
– Cutting hard substances like concrete generates significant friction
– Cooling the blades is necessary to prolong their life
– Water is often used to cool the blades
– Dry cutting should be intermittent and shallow to keep the blade cool
– Adequate cooling prevents blade breakage and potential harm to the operator or nearby individuals

A concrete saw (also known as a consaw, road saw, cut-off saw, slab saw or quick cut) is a power tool used for cutting concrete, masonry, brick, asphalt, tile, and other solid materials. There are many types ranging from small hand-held saws, chop-saw models, and big walk-behind saws or other styles, and it may be powered by gasoline, hydraulic or pneumatic pressure, or an electric motor. The saw blades used on concrete saws are often diamond saw blades to cut concrete, asphalt, stone, etc. Abrasive cut-off wheels can also be used on cut-off saws to cut stone and steel. The significant friction generated in cutting hard substances like concrete usually requires the blades to be cooled to prolong their life and reduce dust.
