Selection of correct diamond blade

If you choose a diamond blade correctly and use it correctly, you will have excellent useful life, disconnection speed, and cost performance. Similarly, if you select a wrong blade or make a mistake, you will hurt the blade and lose. Alternatively, the blade will quickly wear or not cut enough.

There are many factors to consider when choosing which UDT diamond blade to buy. There is something like the following:

price

If you use it frequently or do a large work, choosing a more expensive premium series diamond blade will have a longer life and lower cost per cutting linear meter. However, in case of occasional use or small work, it may be desirable to select a diamond blade in a lo w-priced trading series.

Saw quality and size

• The work depends on the horsepower and number of revolutions of the tools used. Diamond blade is rated according to the rotation speed of saws and grinders. Hig h-speed han d-saw and hig h-speed cut of f-sew require a higher RPM blade. An electric wall chaser requires a different blade from the gasoline type.
• Before choosing a product, check both the side of the machine. By doing so, you can ensure not only cost performance but also more important safety.

Materials to cut

Before choosing a diamond blade, it is most important to correctly identify the cutting material. This has a significant effect on the diamond blade cutting speed and life.

Most materials are classified into four categories: hardware, mediu m-hardware, mediu m-soft, and software. The harder the material to be cut, the softer the bond that holds the diamond. By doing so, the bonds can be worn, the diamonds are exposed, the product can be cut, and the diamonds can be released before the diamonds are glue and the blade becomes useless. Conversely, when cutting soft materials, it is important to use a powerful and hard bond that holds the diamond segment and extends the life of the blade.

Many people choose the hardest blades and believe they can cut anything. This is a wrong idea. With a blade using a hard bond, hard products cannot be disconnected! As a general rule, the most frequently disconnected material or blade performance determines the most important material.

If you use a blade to cut multiple materials (for example, asphalt and concrete), decide which ingredients to cut the most frequently and purchase a blade suitable for that material.

Blade type

The segmented blade has a wider galette (space between segments) to help cool the blade and discharge dust. Also, when used under severe conditions, it prevents cracks. This style blade has the fastest cutting speed, but the cut is the roughest and some chips occur. The more abrasive, the wider the groove. Segment blades with narrow slots are generally for marble and granite, and keyhol e-shaped slot blades are suitable for general use. These blades are usually from medium to hard bonds, long life and durable. The segment blade is ideal for all architectural materials, such as marble, granite slabs, concrete, reinforced concrete, and asphalt. We provide a wide range of blades with a wide diameter, especially in markets with a diameter of 12 inches (350 mm) or more. These blades are often used in masonry saws, concrete saws and circular saws.

Continuous rim blades have a better finish than split blade and longer life. Continuous rim blades are used for wet cutting to cool the blade and wash away the fragments to prevent dust. In general, when cutting hard materials such as tiles, porcelain, granite, stone, glass, etc., the bond becomes softer. Because the cutting edge is flat and continuous, there is no impact that causes the cut to the material. This type of blade is particularly suitable for tiles that require perfect finish. These blades are generally available in diameter 4 "/100mm to 14"/350mm. Small blades of 4 "/100mm to 5"/125mm are often used in handheld grinders, and large sizes are often used in round saws and tiles. J slot design is a variety of continuous rim blades. There is a "J" -shaped slot around the blade edge, which helps to improve durability, extend the blade life, and speed up the cutting speed.

The turbo blade is suitable for a more aggressive and very hard material because the bond is soft. The turbo blade features a continuous rim with a serrated edge. This wav e-type continuous rim reduces the impact on the coveting material when working on the hardest tiles and building materials. These blades usually have a size from 4 inches (100mm) to 12 inches (300 mm). It can be used for grinders, circular saws, tile saws, and can cut various materials such as tiles, stone, marble, granite, masonry, and other hard building materials.

Let's avoid:

General Purpose Blades - These are budget blades that are at the lower end of the price range and are aimed at handymen and light users. General purpose blades usually have a medium segment hardness, making them suitable for cutting a variety of building materials. However, they are not very suitable for harder or abrasive materials like asphalt or limestone, and they wear out very quickly.

Sintered Blades - Sintering is a cheap manufacturing process and is generally considered to not hold the segments on the blade as securely as laser welded blades. If the blade gets too hot, the segments can come off, which not only shortens the blade's lifespan but can also be very dangerous. Always look for laser welded blades, as sintering tends to be used on cheaper blades.

The cost of diamond blades is usually a small factor in the overall cost of the operation. Therefore, it is important to choose a diamond blade that not only has a low blade price, but also one that can provide the best performance and productivity.

What blade do I need for cutting?

There are many variables in choosing a diamond blade, so we always recommend consulting with you about your requirements. Here are the blades by product that we stock and sell.

Asphalt is highly abrasive, so blades wear out very quickly. If you cut a lot of asphalt, be sure to use the United Diamond Tools Black Blade.

Green concrete is concrete that has hardened but not completely set. It may take several months for the blade to fully set. Green concrete is also very abrasive, so use the United Diamond Tools Black Blade or the Early Entry Blade for your Sofcut Saw.

Sandstone and limestone are not as abrasive as asphalt, but still use the United Diamond Tools Black Blade. For reconstituted limestone, we recommend the White Blade.

Concrete, reinforced concrete, concrete curbs, concrete pipes, and concrete paving require the United Diamond Tools Concrete Blade (White).

If you regularly cut a combination of asphalt, limestone, and concrete, we recommend using the gray UDT Combi Concrete/Asphalt Blade. While it is preferable to use the appropriate diamond blade for each material, the gray is best for asphalt and limestone, and also works well for concrete. (You can solve this problem by cutting through the asphalt or limestone to "open" the blade again).

Wall chasin g-There are various thickness and diameter, wall chasing and dedicated blade for grooving.

It is best to cut the exposed aggregate with our black chasing blade. These blades have excellent undercut protection when penetrating to the base. It is also ideal for green concrete. In the case of exposed aggregate pavement, a white blade is required because the composition is different.

Cray paders, which are cut with brick saws, require a Silence Blue Blade for United Diamond Tools. Concrete blades are often sufficient, but there is also a silence blue blade for hand sewn.

Ceramic pavement and porcelain pavement are very hard and very fragile. It's difficult to use your cu t-offsaw, so tile and sewn are much better. The segmented blade lacks pavement materials or shattered. Even a specific stone blade is likely to be missing or peeled off on a very hard surface. To get the best results, use our ultr a-thin blade or a specially prepared Super Turbo blade.

Porcelain is manufactured using very special porcelain soil and is fired at very high temperatures, so it has almost no water absorption and is a very hard tile. "Ceramics" is a general term, not only porcelain, but also terracotta, stone wear, earthenware, etc. Porcelain is a kind of ceramic, but not all ceramics are porcelain.

Alumina ceramics and silver carbide are used to manufacture wear plates. Because it is a ceramic, you need the same blade as porcelain. However, rubber is often attached to aluminum ceramics, making the cutting very complicated. If you consult with the United Diamond tool, we will introduce a blade that can be cut without chipping even such complicated applications.

Since the granite is very hard, a soft bond blade like the UDT Pink Series is required. These blades are worn very quickly when used to cut the high polished material above.

Both fire bricks and marble are very difficult use, and special blade is required to cut without cracks or chips. Please contact UDT for an appropriate blade quote.

Glass fibers and glass require electri c-plated sole blade.

Rescue Blad e-Vacuum Back blade usually cuts various materials, such as concrete, mason, steel, various iron, plastic, tiles, wood, glass. It is also used for cutting rails. It is sometimes called rescue blade because the fire brigade is used in the "rescue" saw. It can be used even in dry state, but using water will last longer.

The core sample blade is widely used for cutting core samples in gold mining and mining in Western Australia. We handle many special core cutting blades for cutting very hard materials.

Houses built decades ago, sometimes weird, such as hidden showers and buried indoor baths.

Recently, Tiktok users who have found an old razor blade from the bathroom wall have become a hot topic.

The old razor blade seems to be due to a small groove on a drug shelf, which is common in houses built before the 1970s. Before plastic disposable razors became mainstream, the Leaders Digest said that this gap was for "disposing" used blades.

The groove was connected to the hole in the wall, so the blade was piled up on the back of the mirror.

An old razor that tiktokers found is released

One of Tiktoker, who first posted a razor's blade at home, is a user who calls Curly Night on the app @carlyknight.

According to her Tiktok video, Knight posted his home in the 1950s and commented that one user had a razor in the bathroom. Knight later showed that there was a small groove on her drug shelf that was written as "used razor disposal."

Since the Knight posted this video, the number of views has reached 3. 8 million, and Tiktokers has jumped in the comments in the comments.

"A user writes about used razor blades:

Another person added: It doesn't just disappear, "people at that time," from invisible to places where they don't care, Beverly. "

Since then, more than 150 people have found a razor groove in a house, which is said to have been built in the 1920s and mi d-1970s in Tiktok. Some users, like @NOAH_QUAY, have removed the cabinet and found dozens of rusted razors.

Melissa Arisa saw Knight's video and immediately checked her bathroom.

Arisa told Insider that she's lived in her 1966 apartment for seven years and never noticed the slot or the word "razor" above it.

"I've seen it a thousand times and never noticed it," she told Insider via Instagram. Because she lives in a rental, she hasn't tried to remove the cabinet to check for old blades.

Homes built before the '70s may still have razor grooves

According to Reader's Digest, blade grooves were prevalent in homes built before the 1970s, when safety razors were common for home use.

In 1903, Gillette introduced the first modern double-edged safety razor. It was a safer and easier option than using a straight-edged razor at the barber's, Gizmodo reported.

Safety razors became popular, but they faced a challenge: how to dispose of the blades.

Throwing them in the trash is unsafe, and the blades can't be burned, Reader's Digest said.

So builders started adding grooves between thumbtacks in walls so that used blades could fall into them. The gaps were big enough to hold thousands of razors, so homeowners could basically forget about the problem.

But today, people who live in or renovate these homes are discovering the quirky feature and the old razors that previous owners left there.
