Every decorator will use the circular saw blade every day. Today, our topic is about it.

Can the woodworking saw blade be installed on the angle grinder for use? Woodworking saw blade What does the number on the saw blade mean? How to select the number of teeth of woodworking saw blade? With these questions in mind, let's enter today's topic.

First, let's have a general understanding of the saw blade. Here I take the doctor's saw blade as an example

Basic Details
250 represents the diameter of the saw blade, which is basically used on a bench saw or a 45 degree oblique cutting machine. 3mm represents the width of the alloy, that is, the groove we cut is 3mm thick, and each knife is 3mm. 2mm represents the thickness of the body. The smaller the cutting thickness is, the smaller the resistance is. It can effectively save wood and is one of the effective ways to prolong the service life of the saw blade. The max8000 represents the rotational speed, and the limit is 8000 rpm. Some woodworking saw blades have a rotational speed of only 6500, which can basically answer the first question. The rotation speed of the angle grinder is 13000 rpm, which can easily cause the woodworking saw blade to fly out and cut to fingers or other parts, which is very dangerous. I do not recommend this (especially for beginners). The figures are basically explained, but there are also some places where the figures are not expressed. The first and most obvious is the color of the saw blade. There are red or black woodworking saw blades in the market. What does this mean? This layer can effectively isolate water vapor, protect the body and reduce the probability of rusting. The second is the noise reduction hole. The four corners of the woodworking saw blade have noise reduction treatment to reduce noise pollution, which is very user-friendly. The third is the type of teeth. The tooth shape of the woodworking saw blade is sharp, which is conducive to cutting wood. The representative tooth shape is the staggered tooth (left and right teeth), which is also the mainstream cutting solid wood, laminates, acrylic, MDF Another type of tooth is the ladder flat tooth (flat tooth). Mainly cut aluminum. The fourth is the clearance between teeth. The larger the number of teeth, the shorter the distance between them, and the worse the chip removal ability. When the chip removal ability is poor, you will find that your material cuts out a black belt with the smell of wood, which is why. Your tuition is different

Third, many people are asked: How many teeth do you need? 40/60/72/80/84/90/96/100, etc. In fact, it is very simple. Many plates on the market are basically 16mm thick. The number of teeth for reference is 60 to 120 teeth. This range can effectively cut plates with a thickness of less than 20mm. The cut sheet is smooth without burrs. The table saw I used is 80 teeth * 250mm, and the effect is very good.
