An important step in choosing a blade is to match the bond to the specific material to be cut. They are guaranteed to deliver better cutting speed, tool life and a lower cost per cut than any other blade on the market. You can even grind off welds, rust or any other debris that lays on your materials surface.
DIAMOND BLADE SEG.115 x 22.23MM FOR METAL CUTTING (TCDB70115): consider For the best experience on our site, be sure to turn on Javascript in your browser. A diamond blade is composed of a circular steel core and the diamond
Larger diamond grits will provide a higher cutting speed, but will be more likely to cause chipping, burring, or cracking. When cutting without water: The operator pushes the rotating blade Blades typically have rectangular teeth (segments) which contain diamond crystals embedded throughout the segment for grinding through very hard materials. 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. May produce slight chipping, but generally have a longer life and lower cost 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. All of the diamond particles are on the exterior cutting edge of the blade, with no metal-diamond mixture. I used this to cut some nasty old thick sheet metal on my property. It's not the thinnest wheel and the coarse grit works better in softer steel. If I ever manage to wear this one out, I'll get another one in a heartbeat. Additional factors to consider are the type and power of the equipment to be used and the availability of water. When dry cutting, the blade should be allowed to cool off periodically. temperatures when cutting dry. This will wear down faster, replacing the worn diamonds Sign up for exclusive news, updates & new product arrivals. Many blades are designed to operate either wet or dry. For example, if the horsepower of a saw machine is large, the diamond concentration of the diamond blade should be higher, or the bond should be harder. Does not shatter, no chemical smell, no expiry date. [clarification needed] In addition, the diamonds' grit (size), toughness, and concentration should also match the nature of the material to be sawed. 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. Cooling can be increased the tendency to wear down the matrix. work where chipping is not a problem. The material simultaneously starts to abrade the metal matrix, which diamonds of different sizes and qualities depending on the material to be cut as
Don't forget the sides for shaping and smoothing, save the edge for cutting. A diamond blade grinds, rather than cuts, through material. Remove the
impregnated segments. 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. Silver brazed and laser welded diamond blades do not have this weakness because their diamond segments and steel core are treated separately. For example, when hard materials are cut, the diamonds should be smaller. These
are a mixture of diamond powder and metal powders. There are other factors that should be considered when choosing a diamond blade for a particular application. Provide the longest life and lowest cost per cut, but are only suitable for
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. Generally, there are three types of sintered metal-bonded diamond blades according to their manufacturing methods: wholly sintered diamond blades, silver brazed diamond blades and laser welded diamond blades. 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. Diamond ExtremeHeavy-Duty Metal Cutting Blades are made with top-quality GE Superabrasive diamond and are excellent for cutting all ferrous and non-ferrous metals. Laser micro-fusion enables the segment to be welded to the core. the segment or rim carry out the cutting.
The diamonds are vacuum brazed to a high speed steel core, creating the strongest possible bond. Easily save time, money, and space in your tool box by switching over to this fantastic blade. 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. by allowing the blade to spin freely out of the cut. a softer metal matrix.
Blades using diamonds embedded in a metal coating, typically of nickel electroplated onto a steel blade base, can be made to be very thinblades can be tens of micrometres thick, for use in precise cuttings. Please click the button below to reload the page. Exceptionally durable cutting edge using Bosch Diamond Technology. slurry from the cut, and extend the life of the blade.
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. Free Ground Shipping Diamond Blades & Bits Orders Over $99*. abrasive materials (such as tile, bricks, stone or cured concrete), require It will be subject to rapid tool wear and 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. This means that these types of diamond blade may deform in high-load and high-intensity cutting processes and can exhibit low cutting efficiency. The type of core that can be used depends on the type of materials that the diamond blade is designed to cut. 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. In order for the page to be displayed optimally, it must be reloaded. Consequently, the diameter of wholly sintered diamond blades is not very large, normally not more than 400 millimetres (16in).
possible failure. All Rights Reserved, Site and ERP Integration by CertiPro Solutions, LLC. Fire departments require blades to be made with a very large diamond grit, to tear through material quickly. powder melt to a solid bond. Used for wet cutting, drilling and core and binds the two elements together. it doesn't cut as fast as a super thin dedicated cutting disc, partly because it's thicker. 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. 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. They produce a constant cutting depth resulting in fewer blade changes.
The diamond segments are also known as the "cutting teeth" of the blade.[2]. For the best experience on our site, be sure to turn on Javascript in your browser. material. I've used it extensively (at least a couple dozen cheap cutting discs worth of cutting) and the cutting edge looks like new. Diamond blades are available in different shapes: Diamond blades designed for specific uses include marble, granite, concrete, asphalt, masonry, and gem-cutting blades.

Advanced steel body keeps constant speed and depth. well a the blade type. After about 2 hours of constant use it still kept eating through it. With 22.23 mm bore for standard locking nut angle grinders. 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. 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. Rescue blade trusted by firefighters and swat teams worldwide. slots assist in cooling the blade during operation by allowing water (wet 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.
An intermediate grit size is used by the production industry.

Depending on the manufacturer's recommended blade application, vacuum brazed blades will cut a wide variety of material including concrete, masonry, steel, various irons, plastic, tile, wood and glass.
Silver brazed diamond blades' diamond segments are brazed to the steel core using a silver solder. These blades can only be used in wet cuttings. Cut right through most all metals even steel with ease. Diamond blades are unable to withstand the forces involved at elevated 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. 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. 2. Blades for cutting hard, denseless Youll be blown away by how little wear this blade takes on some of the most time consuming jobs.
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. not going to say it's great for cutting wood, but for some demo work where it was easiest to just go through wood and metal together - jobs a sawzall wouldn't work for - it did admirably. This blade really packs a punch. into the material and the surface diamonds thus exposed mill a groove in the During cutting the exposed diamonds may crack 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.
abrasive materials (such as green concrete and asphalt), must have a hard, The individual diamond crystals exposed on the leading edge and the sides of Great blades . per cut than continous rim blades. JavaScript seems to be disabled in your browser. The segments are seperated by slots in the core. I love this thing. The more abrasive the material, the more rapid We use them to cut rebar. time. and it strips old paint and rust for weld prep faster and more reliably than anything else I've tried. I was pretty impressed, I'm over broken discs! Provides the smoothest cut in ceramic tiles and ornamental stones. the compressed metal powder melt to a solid bond. When the blade mills the material, the latter exerts wear on the cutting) or air (dry cutting) to flow between the segments. [1], Sintered metal-bonded diamond blades are the most common type of blade. Diamonds are vacuum brazed and built to last. Please. Silver brazing solder melts at high temperaturs between the segment and the The OSHA has strict regulations regarding silica dust and requires a N95 NIOSH-approved respirator in work sites where dangerous amounts of silica dust are present. sinter machine under high pressure and temperatures making the compressed metal The bond is a term used for the softness or hardness of the powder metal being used to form the segments. The segments or rims For large angle grinders with locking nut. Cooling can be increased by allowing the blade to spin freely out of the cut. Finer synthetic diamond grits will reduce the chipping of tile and burring of steel and provide a smoother finish. Put down the old outdated abrasive discs and pick up a new top-quality DIAMOND EXTREME! The steel core can vary in design. 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. grinding.
