CONCRETE SAWS | THE BASICS
Concrete saws, also known as “cut-off” saws and power cutters, are power tools used to cut through thick, solid and hard materials such as tiles, concrete, pavers, masonry, brick and asphalt. These saws blades on these diamond saws can be either of two types: Diamond cutting blades or abrasive cutting blades. Concrete saws come if different styles including hand-held and walk-behind styles. They may run on gasoline, hydraulic power, pneumatic pressure or through electricity.
DIAMOND BLADES: THEIR PARTS AND HOW THEY WORK
Diamond blades have 4 parts in general. Learning about how these parts work will enable you to gauge which kind of diamond blade will work best given the kind of work you intend to use it for.
- METAL CORE. The metal core is a precision-engineered segmented disc that holds the diamonds. The concrete saw & core drill bits spins this disc to enable the diamonds to cut through tough materials like concrete.
- SYNTHETIC DIAMONDS. Diamonds can be very tough and sharp. It is for this reason that diamonds have some of the most varied industrial uses. In this particular application, synthetic diamonds serve as sharp cutting “teeth” that cut through concrete.
- MATRIX. The matrix is a metal bond that holds the diamonds in place until they wear out to reveal newer and sharper diamond “teeth”.
- WELD: The weld attaches the cutting segments to the metal core either through laser welding or soldering.
GUIDE TO BUYING AND CHOOSING YOUR CONCRETE SAW AND THEIR BLADES
Concrete saws can be quite expensive. Costing upwards of $1000, this is a power tool you want to spend some time researching and learning about before you purchase. Below are two major factors you might want to consider when choosing concrete saws.
