Portable table saws are commonly used products along with hand saws because of their versatility, convenience, and savings in both labor and performance. Besides worrying about how to choose the best portable table saw. How to choose saw blades is also a problem for customers
When there are so many brands of portable table saws on the market today, consumers are wondering what to choose. Choosing the right saw blade will not only help you use the product more sustainably and also make the operation more efficient. The ways to choose saw blades for the portable table saw below are hopefully useful information for you.
- Criteria to select saw blades
Number of teeth of the saw blade
The blade with more teeth always makes the circuit more perfect, whereas the smaller number of teeth will make the cutting circuit coarser but cut faster. Therefore, when sawing wood cutting blades with a small number of teeth will be suitable, usually with common wood saw blades 254mm diameter or choose the number of teeth 24. A good wood saw blade will consume less engine power but makes the circuit rougher.
Cross-cutting blades are designed to provide a smooth cutting circuit without leaving marks on the wood profile. This type of saw blade is usually popular with the number of teeth from 60-80, more teeth mean that each tooth will remove fewer wood billets.
The distance between two serrated teeth
In the process of splitting the wood, the gap between the two teeth is larger, leading to faster speeding to push wood billets when sawing. In contrast to the cross-section, smaller wood surfaces require a finer cut so this distance also requires a smaller. On these cutting blades, deliberately creating small spaces is the manufacturer’s intention to limit the low-speed cutting, this is a special problem for multi-angle sliding saws. The flexible distance between two serrated blades is designed to ensure the best harmony between two purposes: sawing and cutting wood
Material saw blades
The material of the saw blade will determine whether cutting is easy, fast and durable over time. If you choose to buy a quality saw blade of a famous brand, the saw blade will be suitable for the outer protective alloy layer to make the cutting and friction saw more smooth. This high-end coating will help increase your work performance and use your saw longer
Choose the thickness of the saw blade
Choosing the thickness of saw blades is extremely important. The saw blade is in direct contact with the wood, so during cutting will increase the temperature of the saw blade to change or damage the saw blade. The thickness of the blade depends on the diameter of the wheel, and the work to be done. The thick blade will withstand the high pressure of cutting from straight cuts of high thickness but will be easy to break if in the process of cutting wood in a curve or twist. Thin saw blades are recommended for use with twisty cuts, but for high-thickness pieces of wood, the thin saw does not.
The angle of the saw blade
The angle of the saw blade is conventional when you look straight at the saw blade from front to back. The vertical line is perpendicular to the vision of the eye along with the inclination of the serrated angle forming the angle of the serrated. The larger this angle means the faster cutting speed and circuit breaker, the smaller the corner means synonymous with smooth cutting but the cutting speed will slow down.
So, of course, the saw blades will have a large angle of saw teeth (usually 20 degrees). While cutting blades for multi-angle sliding saws (ensuring the smoothness of the cutting circuit) will have a small tooth angle (usually 5 degrees). Balanced multi-saw blades between different jobs usually have an angle of 15 degrees.
Cooling for the saw blade immediately after use
Saw blades that come in direct contact with the material during cutting will produce high temperatures. If you use a saw blade for too long a cut, it will cause the blade to break or deform. So the best advice is to cool the saw blades or let the saw blades stop working if you cut them for a long time.
To sum up
The above are some considerations when choosing the right saw blade, hope you will use the saws effectively and safely.
