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.
Youll be blown away by how little wear this blade takes on some of the most time consuming jobs.
Cuts #4 rebar like butter and last a long time. possible failure. 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. It's not the thinnest wheel and the coarse grit works better in softer steel. [1], Sintered metal-bonded diamond blades are the most common type of blade. 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. Blades typically have rectangular teeth (segments) which contain diamond crystals embedded throughout the segment for grinding through very hard materials. A diamond blade is a saw blade which has diamonds fixed on its edge for cutting hard or abrasive materials. Skip to the beginning of the images gallery, Diamond Extreme HD Metal Cutting Blades with Side Coating (Sizes 12" to 16"). I used this to cut some nasty old thick sheet metal on my property. Buying a second one after 2 years of intermittent use. Pressed with hot press machine under high temperature and pressure, making
Cut right through most all metals even steel with ease. 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. There are other factors that should be considered when choosing a diamond blade for a particular application.
Rescue blade trusted by firefighters and swat teams worldwide. An intermediate grit size is used by the production industry. 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. First pressed with a press machine under normal conditions, then laid in Harder materials need a softer bonded segment to allow for continuous diamond exposure.
The blade should be allowed to cool off periodically. These well a the blade type. 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 bond is 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. 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. Find registered products - in the old Portal, Learn about Bosch Professional Measuring Tools, Calibration procedures for measuring tools, EXPERT Diamond Metal Wheel Large Size Cutting Discs, Robert Bosch Power Tools GmbH 2021, all rights reserved, Paper / Cardboard / Corrugated board - Packaging, folded carton, with Euro hole. but it cuts, and cuts, and cuts, and you can use it for jobs that are likely to bind or grab resulting in broken cutting discs and it won't break or bend. 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. 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. Laser micro-fusion enables the segment to be welded to the core. 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. Please click the button below to reload the page. 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. 2022. condition. The diamond segments are also known as the "cutting teeth" of the blade.[2].
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. If I ever manage to wear this one out, I'll get another one in a heartbeat. into the material and the surface diamonds thus exposed mill a groove in the
Used for wet cutting, drilling and
Diamond blades are available in different shapes: Diamond blades designed for specific uses include marble, granite, concrete, asphalt, masonry, and gem-cutting blades.
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. With 22.23 mm bore for standard locking nut angle grinders. The individual diamond crystals exposed on the leading edge and the sides of
I love this thing. work where chipping is not a problem. General purpose blades are also available. The segments are seperated by slots in the core. Available product variations: It will be subject to rapid tool wear and
slurry from the cut, and extend the life of the blade. 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. The steel core can vary in design. 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. We use them to cut rebar. Recommended Price: R206.77. sinter machine under high pressure and temperatures making the compressed metal
abrasive materials (such as green concrete and asphalt), must have a hard,
The type of core that can be used depends on the type of materials that the diamond blade is designed to cut. Only registered users can write reviews. For large angle grinders with locking nut. This will wear down faster, replacing the worn diamonds
If they are used in dry cuttings, the silver solder may melt and the segments can break from the steel core and become a serious safety hazard. 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. JavaScript seems to be disabled in your browser. a softer metal matrix. 2. Silver brazing solder melts at high temperaturs between the segment and the
All of the diamond particles are on the exterior cutting edge of the blade, with no metal-diamond mixture. The segments or rims
When dry cutting, the blade should be allowed to cool off periodically.
An important step in choosing a blade is to match the bond to the specific material to be cut. The diamonds are industrial the compressed metal powder melt to a solid bond.

It will greatly reduce the amount of harmful dust created by cutting.
or break. The diamonds are vacuum brazed to a high speed steel core, creating the strongest possible bond. 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. Blades for cutting soft, When the blade mills the material, the latter exerts wear on the slots assist in cooling the blade during operation by allowing water (wet After about 2 hours of constant use it still kept eating through it. Put down the old outdated abrasive discs and pick up a new top-quality DIAMOND EXTREME! 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. in short: if you're thinking to get one, just do it - you won't regret it. Cooling can be increased I've used it extensively (at least a couple dozen cheap cutting discs worth of cutting) and the cutting edge looks like new. the tendency to wear down the matrix. safety for your health and the people around you, Gloves for easy handling of material and hand protection. The more abrasive the material, the more rapid 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. Don't forget the sides for shaping and smoothing, save the edge for cutting.
blade. 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. Easily save time, money, and space in your tool box by switching over to this fantastic blade. core and binds the two elements together. These blades can only be used in wet cuttings. May produce slight chipping, but generally have a longer life and lower cost 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. the segment or rim carry out the cutting.
without segment loss. per cut than continous rim blades. CAUTION:
Advanced steel body keeps constant speed and depth. For example, when hard materials are cut, the diamonds should be smaller. It is advisable to always have the following items nearby and in a good
are a mixture of diamond powder and metal powders. Silver brazed and laser welded diamond blades do not have this weakness because their diamond segments and steel core are treated separately. You can even grind off welds, rust or any other debris that lays on your materials surface. abrasive materials (such as tile, bricks, stone or cured concrete), require
Diamonds are vacuum brazed and built to last. They produce a constant cutting depth resulting in fewer blade changes. and it strips old paint and rust for weld prep faster and more reliably than anything else I've tried. Diamond blades are unable to withstand the forces involved at elevated
Additional factors to consider are the type and power of the equipment to be used and the availability of water. 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. 
This blade really packs a punch.
