How To Choose The Best Quality Saw Blade

Have you ever questioned why there are so many types of saw blades? Saw bladesare needed to cut a variety of materials but before that it is important to know that saw blades are designed to work best when used for a specific cutting operation. 

There are two basic operations that we need to know, these are cutting across the grain or cross cutting and cutting along the ripping. On this article I will be giving you some basic information which will help you make the best decision in choosing a best quality saw blade.

 

 

The Parts of a Saw Blade

Bore  - is the hole in the center of the blade. This part must match the size of the arbor on your power tool. It must fit snugly or the blade will vibrate and will not function properly.

 

Body  - this part is the steel plate that the blade is formed. More certainly if the blade is made of low quality steel, it won't cost you that much but it will not last longer and the performance of the blade is compromised. If you want higher quality steel saw blades, the price might be high but the performance, precision and durability of the saw blade is guaranteed. 

 

Teeth  - the teeth are points on the circumference of the body that are used in cutting. Most of these teeth are made of tungsten carbide tips welded to the tooth. Tungsten carbide tips are chosen because of its resistance to impact and abrasion. Thus the sharpness of the teeth relies on the quality of the tungsten carbide tips. Saw blades with more teeth will cut smoother than saw blades with fewer teeth but fewer teeth will feed faster and easier than those with many teeth but the cut will not be smooth.

 

Gullets  - the gullets are the spaces in front of the teeth that collects the saw dust from the cut. The more teeth a saw blade has the smaller the gullets will be. Saw blades with fewer teeth will have larger gullets to allow more sawdust to be carried as each tooth passes through a cutting material.

 

Hook angle  - this part is the angle of the face of the tooth that is measured from a center line drawn directly from the center of the bore. With a positive hook angle the face of the tooth is angled forward toward the material the saw blade will cut. With a negative hook angle the face of the tooth is angled away from the material the saw blade will cut. A positive hook angle feeds easily and quickly while a negative hook angle will require more force and will cut slower.

 

 

Now you have a basic understanding of the parts of a saw blade. We will now know tips on how to aim better cuts from your saw blade.

 There are several things that you can perform to ensure that you get the best cuts while preserving the life of your saw blade. Just follow the tips below to achieve a chip-free cuts.

 

 

 

Using the right saw blade and proper alignment:

1.  Make sure to always use the right blade for every specific material that you are cutting. Different types of material may require you to use a different style of saw blade. (Tip: Use a triple chip grind blade with 80 teeth for particleboard or MDF.)

2. Before you work make sure to use a properly tuned saw, and your fence and miter slots are aligned parallel to the blade. When you have blades perfectly parallel to the fence it helps avoid back cutting whether you are using a single blade or a two blade system. Also, keep your saw blade teeth raised so that half the carbide is showing over the stock.

3. Always work with the proper blade configuration with the correct amount of teeth, TCG grind, and the correct prescore. If the prescore is not used, be sure to use a high ATB blade.

4.  Choose a precise saw blade with the appropriate tip configuration for the machine and material being used. Tensioned to the motor rpm of the machine it is used on, and a micrograin carbide designed for longer life on composite materials.

5. Cermet II is a longer life tip material that is both longer and tougher lasting than carbide.

6. Maintain proper Blade Projection.

7. The blade projection can have a great effect on the surface finish. So when cutting, the blade projection is the distance from the top of the material to the top of the blade. . Keeping a blade projection between 20mm and 30mm should ensure a clean surface finish.

8. Always cut with a sharp saw blade. Cutting with a sharp  saw blade  will give cleaner, smoother cuts, and will help to extend the life of your saw blade. Conversely, if you try to get a few more cuts out of your saw blade between sharpening just to save a little money can result in diminishing the sharpening life of your saw blade, give bad cuts, and is potentially dangerous.

9. When having your saw blade sharpened check first if the sharpening shop is properly matching the prescore to the main blade.

10. Make sure the saw flanges are burr-free and clean.

11. Keep the mounting surfaces clean. Any debris on the mounting surfaces can cause the bade to sway, resulting in removing many of the teeth from the cut on the sides and increasing the kerf of the cut.

12. Chips and dust in the cutting path on the material can also impact the horsepower consumption, vibration, feed rate, and heat build up which will have a negative effect on the tool life and the finish.

13. Finally, keep blades from binding in the cut.

 

 

 

Now you are ready to purchase your best quality saw blade and to use it for a better result. For more information visit www.rockhardtools.myshopify.com
