Diamond Saw Blades Information by Category & Materials:
Laser welding is typically used when dealing with extremely hard or abrasive materials. It is a must for cutting asphalt, green concrete, reinforced concrete, metals and other highly abrasive or dense materials.
Sintered diamond blades are used commonly for general purpose cutting of concrete, brick, block and stone. All continuous rim blades are only sintered because they do not permit laser welding such as segmented diamond blades.
Silver brazed welding is used quite frequently for cutting marble and granite. This type of welding is ideal for large diameter saw blades used by quarries. Silver brazing allows re-tipping of the segments so the costly steel core of large blades can be reused. The downside is they can only be used with water or the silver welding could be damaged by excessive heat.
Electroplated saw blades have diamonds impregnated onto the metal base. They can be made very slim and are ideal very high precision cutting. They can be used for cutting graphite, soft ferrites, frozen goods and similar materials.
Turbo diamond blades are continuous rim sintered saw blades typically used for general purpose cutting. They provide a fast aggressive cut due to the serrated segment style however they compromise blade life for cutting speed.
Turbo segmented saw blades are ideal for cutting extremely hard materials as the spaced turbo segments allows them to be laser welded onto the core, unlike continuous rim turbo blades which can only be sintered.
Silent core diamond blades have laser cutouts in the steel core to help reduce the vibrations caused from cutting which reduces the sound levels a significant amount. There's also copper sandwiched silent cores which are multi-layered with a copper plate in the center to help absorb vibrations. Silent core blades are used commonly for quarries or cutting jobs done in residential areas to help reduce the amount of noise pollution.
Continuous rim blades are thin kerf diamond blades used for cutting fine or semi-precious materials where precision cutting is necessary. They are commonly used for cutting tile, ceramics, glass and other materials which are prone to chipping.
A wet saw is used mainly for cutting through dense material such as tile, marble, granite, or other types of stone. A wet saw uses a diamond blade which consists of small fairly even particles of diamond that slowly wear down over time exposing fresh diamonds in their place. This is unlike the common saws you see used that have teeth or rough edges for cutting through softer material and is actually dull to the touch.
When cutting through dense material or performing deep cuts, you will need higher horsepower (HP) equipment. A high HP wet saw will produce enough power and is designed with its own water cooling system already built in. A wet saw typically has a container built onto the machine that distributes water over the blade keeping it cool. Not only will this help prevent you from breathing harmful dust particles, but will also keep the material you are cutting cool and less likely to break due to heat.
When choosing where you are going to cut with a wet blade you will want to consider a few things. Yes, this can be as messy as it sounds and is recommended to be done out doors. You will also want to look at the type of saw you have. If it is a fresh water source you will need to ensure that you are in fact near a water source to use. If a water source can not be obtained you may want to consider using a recirculating pump tile saw which will recycle and filter the water you are using. For your safety you will want to check your water level after each cut to ensure the machine is being used properly.
If you are able to use shallower cuts or are restricted to cutting indoors, a dry blade may be the way to go. Although a dry saw will produce more dust, when working in doors dust can be much easier to clean up than mud and grit that a wet saw may leave behind. A dry saw can also be more convenient to use if you need to make shallow cuts or detailed cuts since there is a wide variety of hand held saws made for this.
Almost all dry cut diamond blades can be run as wet blades. However, wet cut diamond blades can by no means be ran dry. This is due to the fact that dry blades are designed with special teeth to allow air to flow more sufficiently over the blade cooling it as you cut and allow the blade to run more freely. For example, putting a dry blade on a wet table saw will just allow the blade a little extra cooling. If you were to reverse this however and put a wet blade on a dry machine without any cooling at all, the blade will become too hot damaging the machine itself, the material you are cutting or the handler.
These types of diamond blades are have a soft bond ideal for cutting concrete reinforced with steel rebar, old cured concrete, reinforced concrete tubing and other extremely hard materials. They are typically laser welded for the high level of density found in these materials.
Asphalt diamond blades have a hard bond designed for long life while cutting highly abrasive materials such as asphalt over concrete, asphalt with aggregates, freshly poured green concrete and other similar abrasive materials. When cutting asphalt or fresh concrete, laser welding is a must. It is also preferable to have special drop segments or inserts to protect against undercutting beneath the segments where the abrasive slurry can accumulate.
Masonry diamond blades can vary quite a bit due to the wide variety of materials found in this category. Some blocks may be soft but highly abrasive while other materials such as refractory brick can be extremely dense. Always make sure to specify exactly which type of brick, block or stone you are cutting to ensure you get the best blade to match the bond to your material.
These continuous rim diamond blades are designed for chip-free cutting of glass, tile, ceramics, porcelain and other fragile materials where chipping must be avoided. They are commonly used for building, home improvement, renovations and other household repairs or installations.
These diamond blades are commonly larger in diameter and often times silver brazed to allow for re-tipping of the segments to preserve the costly core. Quarries use these types of saw blades for cutting large blocks into smaller slabs to be prepared for polishing and preparation for commercial use.
Tuckpointer diamond blades are used commonly for removing old mortar from brick walls and restoring it with fresh cement. They can also be used for many other practical applications where a wider cut may be necessary by the user. They are similar to loop blades but don't require large equipment to be used. One advantage is that they can be used on easily attainable angle grinders for the average DIY user.
Concave diamond saw blades are ideal for curve cutting applications. They are used for sculpting, installations in countertops and many other uses which require curve cutting which cannot by achieved by normal straight edged diamond blades.
