What are Diamond Blades and Their Types

Diamond is counted amongst the most problematic substances present on the earth. Diamond has many uses beyond expensive jewelry. Diamond possesses some unique chemical properties, making it useful as an industrial abrasive and cutter, and is bonded onto many saw blades. 

Diamond jigsaw blades, buzz saw blades, and hole saws are just a little sample of the diamond blades construction workers and industrial tradesmen use a day.

What is a Diamond Blade?

Diamond is best for non-metallic, abrasive materials such as; concrete, stone, ceramics, and other difficult grind materials. It's not, however, as useful to chop steel and metals as its cousin CBN. Whether sawing concrete, cutting holes in ceramics, or making precision cuts in fiberglass, a top-quality diamond blade is mandatory. 

The advantages of using diamond blades are vast, and that they have distinct advantages over conventional abrasive wheels and other cutting blades wont to make precision cuts.

Choosing the proper cutting blade is as important as selecting the appropriate saw. When properly matched to work, diamond blades cut fast and supply long service life. But using the incorrect knife or a saw that turns the edge at improper speeds can shorten blade life and lift cutting costs.

Diamond blades are available in the right sort of sizes and performance levels; selecting the right edge isn't a simple task. Also, blade costs vary widely and stretch into the thousands, counting on quality. Although it's tempting to shop for a lower-cost blade, in the end, it'll likely be wiser to shop for a costlier, high-performance blade that's designed to last longer.

Many factors affect blade life, such as:

  • blade quality
  • characteristics of the concrete being cut
  • saw speed. 

Knowing how a diamond blade works and the features that affect blade life and performance can improve productivity and economy.

How does a Diamond Blade Work?

Precisely, diamond blades don't cut any material, but they grind. The diamond crystals bonded on the top of the saw do the grinding work. Trailing behind each exposed Diamond may be a "bond tail," which supports the Diamond. The blade rotates through the fabric. 

The exposed surface of the diamonds grinds the fabric into a fine powder. After several thousand passes through the fabric being cut, the exposed diamonds begin to crack and fracture. The matrix holding the Diamond also begins to wear away.

Eventually, the Diamond completely breaks up, and its fragments are caught in a frenzy with the fabric that it's grinding.

As the diamond fractures, controlled erosion of the metal bond containing the Diamond exposes new sharp diamond points. This abrasion and exposure cycle continues until all of the diamond and metal bond section of the segment is gone. Once the cutting section is consumed, the blade will not grind, letting the operator realize it is time for a replacement blade.

Essential Considerations While Using Diamond Blades

  • Ensure the safe and correct installation of the diamond blade on the machine, also confirm that the directional arrow on edge matches the arbor rotation on the saw.
  • When operating the Diamond saw, always use appropriately adjusted blade guards.
  • Never forget to wear proper Personal Protective Equipment – eye, hearing, respiratory, gloves, feet, and body.
  • Always suits OSHA regulations by using approved dust control measures (supply water to the saw).
  • When you need to do the wet cutting, make sure that there's an adequate water system. The insufficient water system can cause blade overheating and failure of the segment or core.
  • If employing a high-speed saw, never make long continuous cuts with a dry diamond blade. Let the blade rest for some time and then start cutting again.
  • Allow the Diamond to chop at its speed and never force a diamond blade into the workpiece.
  • Do not allow the diamond blade to chop through the concrete or asphalt into the "sub-base" material, as this may end in excessive wear and failure of the blade.
  • Never use a damaged blade or a blade that exhibits excessive vibration.

Types of Diamond Blades

Types of Diamond Blades

Here are three sorts of diamond saw blades and their uses.

  • Segmented Rim

One of the most critical problems with diamond saw blades is overheating. The resources available to you'll play an outsized role: choose what saw blade to settle on. The segmented rim blade is useful once you don't have access to water to chill your blade.

Usually, this sort of blade is split into 10 to 14 segments with a deep groove between each section. As mentioned before, this blade may be an excellent option for once you don't have access to water because the tracks within the rim leave sufficient heat transfer. 

Being careless while using the blade can overheat the blade. These blades are commonly used for grinding concrete and bricks.

  • Turbo Rim

The turbo rim blade has many similar features because of the segmented rim blade. Though they appear very different, the anatomy of the blade is just about an equivalent. The turbo rim blade is split into sections and has relief holes to permit better heat transfer.

One of the most important differences between the turbo rim and the segmented rim blades is how it handles heat. The turbo rim is often run wet or dry. The holes within the blade act much like an equivalent because the grooves on the segmented rim blade permit better heat distribution.

Again, very similar to the segmented rim blade, the turbo rim can cut concrete and brick. However, unlike the segmented rim, the turbo rim also can cut harder limestone materials. Because there are no breaks within the rim, you're left with an excellent, clean-cut compared to the segmented rims movie.

  • Continuous Rim

This type of blade is usually called the wet cut blade, as there's no inbuilt heat distribution or fan-like features to push air over the blade. These blades are generally very flat with few details because this blade has no inbuilt heat distribution; you would like to run it with water flowing over it. The water goes to remove dust from the environment keeping your equipment clean and lasting longer.

The continuous rim blade can manufacture a clean edge while cutting marble, granite, porcelain tile, and ceramic tile. This sort of blade is additionally one of the slowest cutting.
