If you want to make your table saw as the best one? Then you need a best blade to operate it. Are you already having a table saw? are you sure that your table saw is cutting well? if not, then you need to be change your table saw blade. Here the problem is, there are enormous selection of saw blades are available, in that you need to select a best blade for it.
To make your work simple to select the right table saw blade you need to understand the basic facts about the table saw blade. Here we are explaining you various facts about the table saw blades with its types.
4 Table Saw Blades
- Flat top grind or FTG.
- Alternate top bevel or ATB.
- Combination or ATBR.
- Trible-chip grind or TCG
Flat top grind or FTG:
The FTG blades have a teeth whose edges are square to the table saw plate. It is also called as rakers, these teeth attack the wood much like a chisel chopping out of the ends of a mortise. These kind of blades are fast enough for cutting and durable, but they won't create a clean surface.
This kind of plates are particularly designed to rip and sawing perpendicular to the grain.
Alternate top bevel or ATB:
In this kind of blades, the teeth are angled across the top of the edge with every other tooth leaning in the opposite direction. The shape of the tooth will cause it to shear the wood fibers cleanly using a slicing motion.
The steeper, the bevel angle, the cleaner teeth cut are quicker they will dull. The most 40 tooth ATB blades are marketed as all purpose blades.
Combination or ATBR:
The combination blades are consists of 50 teeth which are arranged in the set of five. If you have a table saw with 4 ATB teeth which is followed by a raker tooth that is known as the ATBR designation. The ATB teeth are designed in the manner to cross cut cleanly while the raker teeth aid in ripping. The combination blades are also considered for all-purpose blades.
Trible-chip grind or TCG:
The teeth on a TCG blade is an alternate between the raker tooth and a chamfered tooth. The chamfered tooth cut out the wood roughly, whereas the following FTG tooth will clean it up. This tooth configuration is meant for cutting the materials with higher density like plastic laminate, solid surface materials like Corian, and non-ferrous metals like brass and aluminum. Pointy ATB teeth would blunt quickly from this stuff.
When you prefer the table saw’s for your work, in addition to cutting the lumber many other wood working projects may also done like plywood, particle board, MDF, hardboard, plastic laminate and other materials. Now let us take a look on the blade choice based on the type of work you are performing and the type of material you are cutting.
Blades used for ripping:
When you cut the wood material with a rough-ripping to break down a board into small parts, then 24-tooth FTG blade is good for your selection because it will cuts the wood evenly, when it was a hardwood also.
A back point about this cutting is, it does not cut the wood very smoothly, but due to the piece will be sawn to final dimension later, it does not take as a matter.
There are 40 to 50 tooth all purpose or combination blades are available which will also do the trick, yielding a cleaner cut than a 24 tooth blade. On the other hand, the cut from the high-quality blade will be clean enough to serve as a finished surface after just a bit of fine sanding.
Whatever it is, this kind of blades won't rip as fast as a 24 tooth blade and you will have to feed thick hardwoods more slowly into the saw. When you using this saw to cut the thick wood or high-density wood to have a finished width you can use a 24 tooth blade, which is ripping the piece of 1/32” oversized then trimming it to the finished width by taking a single pass over the jointer.
Some of the blades are incorporated in the anti-kickback shoulders, that helps you to prevent the overfeeding which can be invite to take a kickback. If you work without a splitter on your saw, then this kind of blade is safer selection.
Blades used for cross-cutting:
This blade is used for sawing the wood across the grain invites to exit tear-out. If you want to minimize this, then cross-cutting the blades will employ the ATB teeth for their shearing action. When the number of teeth is higher than the cleaner cut which is the reason for why crosscutting blades have a 60 to 100 ATB teeth.
This is a blade which looks like an excels at getting the cleanest crosscuts and miters. It is recommended that you can use a 40 tooth ATB or 50 tooth combination blades for crosscutting. It may not be slice quite as cleanly as an 80 or 100 tooth blade.
While you using this kind of blades it will saves you from the trouble of constantly switching from a rip blade to a crosscut blade. It is also possible to do the cross cutting of woods on the table saw with a 40 teeth ATB blade. And also you can use the 80 tooth ATB blade for performing the cross-cutting or sawing of delicate sheet goods.
Blades used for sheet goods:
The special kind of wood materials which are named as sheet goods including the plywood, particleboard, melamine, MDF, hard board and plastic laminate are need a special type of blades for cutting it.
Because this kind of wood materials are having a thin veneers and the plywood is prone to tear-out, especially when you are cutting across the face veneer. It is best to cut this kind of materials with the ATB blades and more teeth blades.
Whatever it is, a good quilty all-purpose blades will do a fine cutting in most of the cases. On the other hand, when you go for cutting the wood materials like particleboard, melamine, MDF, and hardboard are all fairly dense materials which can be hard on the saw teeth.
Cutting this kind of materials with a inside stuff by using an ATB blade will wear down its pointy tips quicker than most of the solid wood materials. However, the shearing action of the ATB teeth blades will provides a clean cuts in these chip-prone materials, so that it is a fair trade-off.
Where as you go for cutting the laminate materials which are having high density than the ATB blades which are having tough on the tips of the teeth will prefer as a best one to cut it. If you work with it a lot, then it is worth for investing in a TCG blade for the purpose. Otherwise, your ATB blade may take sooner than the desired trips to the sharpeners.
