For tradespeople and construction workers who are fed up with burning through bonded discs and money, the Bosch EXPERT Diamond Metal Wheel Large Size Angle Grinder Cutting Disc offers a whole new way of cutting metal. These blades consist of a steel core (the base is steel plate, unlike that of the wires used in diamond wire saws) and diamond segments, which are made by combining synthetic diamond crystals with metal powder and then sintering them. Some cores have spaces (known as gullets) between segments to provide cooling and slurry removal, while others have a single continuous rim for smoother cutting. slots assist in cooling the blade during operation by allowing water (wet
Otherwise, it is possible for the diamond segment itself to break or the steel core below the segment to wear and break, creating serious safety hazards. Water will prevent the blade from overheating:
Used for wet cutting, drilling and

I've used it extensively (at least a couple dozen cheap cutting discs worth of cutting) and the cutting edge looks like new. Silver brazed diamond blades' diamond segments are brazed to the steel core using a silver solder. cutting) or air (dry cutting) to flow between the segments. Cutting metals such as steel and cast iron has traditionally been tough on angle grinder discs, and many workers are familiar with the chemical smell of bonded discs burning away while they cut. The bond is a term used for the softness or hardness of the powder metal being used to form the segments. Provides the smoothest cut in ceramic tiles and ornamental stones. it doesn't cut as fast as a super thin dedicated cutting disc, partly because it's thicker. Silver brazing solder melts at high temperaturs between the segment and the
Harder materials need a softer bonded segment to allow for continuous diamond exposure. temperatures when cutting dry. Consequently, the diameter of wholly sintered diamond blades is not very large, normally not more than 400 millimetres (16in). are a mixture of diamond powder and metal powders. These include the type (manufacturing method) of the blade, the availability of water in the cutting process, the horsepower of the saw, and the acceptable level of noise created by the saw. General purpose blades are also available. There are many types of diamond blade, and they have many uses, including cutting stone, concrete, asphalt, bricks, coal balls, glass, and ceramics in the construction industry; cutting semiconductor materials in the semiconductor industry; and cutting gemstones, including diamonds, in the gem industry. This will wear down faster, replacing the worn diamonds
They produce a constant cutting depth resulting in fewer blade changes. During cutting the exposed diamonds may crack
Water will prevent the blade from overheating, greatly reduce the amount of harmful dust created by cutting, remove the slurry from the cut, and extend the life of the blade, since diamond is unable to withstand the forces involved at the elevated temperatures involved in dry cutting ceramic and abrasive materials, and will be subject to rapid tool wear and possible failure. A wholly sintered diamond blade is made by putting the steel core, together with the diamonds and the metal bond materials, into a mold and then sintering it in a sintering furnace equipment. Remove the
Follow us on following social media platforms to know what we are up to, Call us any time, You will get straight through to, Delta Diamond. The steel core can vary in design. A laser melts and combines the metal of the diamond segment and the steel core creating a stronger weld, which can hold the segments even in high temperatures, meaning that laser welded diamond blades can be used to cut many types of stone without water cooling. First pressed with a press machine under normal conditions, then laid in
It will greatly reduce the amount of harmful dust created by cutting. A diamond blade grinds, rather than cuts, through material. a softer metal matrix. The individual diamond crystals exposed on the leading edge and the sides of

Recommended Price: R206.77. When dry cutting, the blade should be allowed to cool off periodically. The steel core can be quenched and processed with other heat treatments, so its hardness and strength can be high, meaning that the blade can be used in high-load and high-intensity cutting processes with high cutting efficiency and a smaller degree of deformation. This blade really packs a punch. Great blades . All of the diamond particles are on the exterior cutting edge of the blade, with no metal-diamond mixture. into the material and the surface diamonds thus exposed mill a groove in the
The diamonds are vacuum brazed to a high speed steel core, creating the strongest possible bond. Only registered users can write reviews. Provide the longest life and lowest cost per cut, but are only suitable for
You can even grind off welds, rust or any other debris that lays on your materials surface. However, when cutting very hard or abrasive materials, e.g., concrete containing reinforcing rebar, laser welded diamond blades should also be used with adequate water. Rescue blade trusted by firefighters and swat teams worldwide. You have successfully added product to the cart. They are guaranteed to deliver better cutting speed, tool life and a lower cost per cut than any other blade on the market. powder melt to a solid bond. When water cannot be used (in, for example, electrical saws), measures should be taken to ensure that the operator does not inhale the dust created by the process, which can cause silicosis, a serious lung disease. The diamond segments are also known as the "cutting teeth" of the blade.[2]. Cut right through most all metals even steel with ease. Easily save time, money, and space in your tool box by switching over to this fantastic blade. With 22.23 mm bore for standard locking nut angle grinders. All Rights Reserved, Site and ERP Integration by CertiPro Solutions, LLC. A diamond blade is a saw blade which has diamonds fixed on its edge for cutting hard or abrasive materials. Additional factors to consider are the type and power of the equipment to be used and the availability of water. The type of core that can be used depends on the type of materials that the diamond blade is designed to cut. Silver brazed and laser welded diamond blades do not have this weakness because their diamond segments and steel core are treated separately. releases more diamonds. Available product variations: the segment or rim carry out the cutting. The bond controls the rate at which the diamond segments wear down allowing new diamonds to become exposed at the surface to continue grinding with a "sharp" edge. Because it is participating in the sintering process, the steel core cannot be quenched, so the hardness and strength of the core are not very high. well a the blade type. With the EXPERT Diamond Metal Wheel, this smell can be consigned to the past as can regular trips to a shop to buy new metal discs.

Last over 100X longer than abrasive wheels while generating fewer sparks and less dust. Softer materials like asphalt or freshly poured concrete can use a harder segment to resist the increased wear that softer, abrasive materials create. When the blade mills the material, the latter exerts wear on the
There are other factors that should be considered when choosing a diamond blade for a particular application. Diamond blades are available in different shapes: Diamond blades designed for specific uses include marble, granite, concrete, asphalt, masonry, and gem-cutting blades. without segment loss. ground and cut a bunch of aluminum with it too - it gums up, but not near as bad as silicate, and a quick hit on some mild steel will clean it up for more use. Buying a second one after 2 years of intermittent use. and it strips old paint and rust for weld prep faster and more reliably than anything else I've tried. safety for your health and the people around you, Gloves for easy handling of material and hand protection.

These blades can only be used in wet cuttings. Sign up for exclusive news, updates & new product arrivals. Higher diamond concentration will decrease the impact on each single diamond in working, while a harder bond will hold the diamonds more firmly. Diamonds are vacuum brazed and built to last. 2022. For example, when hard materials are cut, the diamonds should be smaller. Finer synthetic diamond grits will reduce the chipping of tile and burring of steel and provide a smoother finish. An intermediate grit size is used by the production industry. However, diamond tools and blades work better when wet, and dry cutting should be limited to situations in which water cannot or should not be used. JavaScript seems to be disabled in your browser.

The blade should be allowed to cool off periodically. After about 2 hours of constant use it still kept eating through it. This means that these types of diamond blade may deform in high-load and high-intensity cutting processes and can exhibit low cutting efficiency. Vacuum brazed diamond saws are manufactured by brazing synthetic diamond particles to the outside edge of the circular saw blade in a vacuum brazing furnace. I was pretty impressed, I'm over broken discs! Larger diamond grits will provide a higher cutting speed, but will be more likely to cause chipping, burring, or cracking. the tendency to wear down the matrix. A diamond blade is composed of a circular steel core and the diamond
