Table Saw Blades
THE WORKHORSE OF YOUR TABLE SAW
Put plain and simply without a blade your table saw isn’t much use to you. It is an integral and vital part of your table saw but how much do we take the table saw blade for granted? It can be the cause of intense frustration if you are continually having to refine or sand away rough cuts or deal with chips or poorly fitting joints but this doens’t mean that you need a different blade for each type of wood that you cut. Choosing the correct blade can immediately improve your output and does not need to make a dent in your pocket.
Types Of Table Saw Blade
There are four basic types of blade. They are categorised according to the shape of their teeth. The four types are as follows:
Flat Top Grind – These blades are for rough cutting and are not suitable for precision cuts. They work like a chisel and are also called rakers. The advantage with these types of blades is that they are fast.Freud 10 In. 24 Tooth Heavy Duty Rip Blade with 5/8 In. Arbor and PermaShield Coating (LM72R010) is one example of such a blade.
Alternate Top Bevel – These blades shear the wood cleanly using a slicing movement. The teeth are alternately angled in opposite directions and they are generally sold as all purpose blades.
There’s several sub sections in this type, such as Framing Saw Blade, Arbor Finish Saw Blade so please do check when ordering.
Combination – These blades can also be considered for general purposes with 40 – 50 teeth arranged in sets of 5 alternating every fourth alternate top bevel tooth with a raker tooth.
Triple Chip Grind – These blades have alternate chamfered teeth with raker teeth. This arrangement is intended for dense products such as solid surface materials as the teeth don’t blunt so quickly.
Ideal for plastic laminate sheeting, laminate and melamine where chip free cuts are essential.
Generally, it is said that the more teeth a blade has the smoother and slower in cuts while the less teeth it has the faster and rougher it cuts.
So, which blade should you choose? Broadly speaking, for the majority of your jobs a good quality, all purpose combination blade will suffice. However, you need to bear in mind that the finished result will reflect the quality of the tools used. There is a huge difference between the finish on a piece of wood cut by cheap rough blades and that on a piece of wood cut by refined, high quality blades. This is one area where skimping on cost will be a false economy.
Blades for ripping
If you’re wanting blades for ripping solid wood, then a 24 tooth FTG should be what you need if you’re wanting a fast cut, but might be rather rough. Using a slower cut 40 teethATB blade, will get you a smoother cut. There’s also a few Blades for ripping which incorporate anti kickback protection, so keep this in mind too.
Blades for cross cutting solid wood
Cutting solid wood or plywood the rule of thumb here is the more teeth, the cleaner the cut. So you’re best to keep this in mind when selecting the blade. Using 60 to 100 ATB teeth blades will get you the smoothest of cuts, but the 40-tooth ATB or 50-tooth combination blades are also suitable for crosscutting.
Blades for sheet goods
Particleboard, melamine, MDF, and hardboard are all considered to be quite dense materials meaning that they can be quite hard on saw teeth. Using ATB blades on these materials will shorten the blade life. Now these materials aren’t as bad as plastic laminate which is tougher on the tips of ATB teeth, due to this being very dense and will blunt your blades a lot quicker. A Triple Chip Grind blade might be a sound purchase if this is a regular material you’re cutting.
Table Saw Blades Final Thoughts
Don’t forget to order the correct size, 8-Inch, 9 In 10 In, 12 In please do double check. 7 1/4 to 14″ is a big noticeable difference in size, but if you’re ordering online it’s best to check before paying that you’ve got the right size blade.
