TPI is the number of teeth the blade has per inch. If you’re looking to cut wood or other soft materials, you’ll need a blade with a TPI of 6 up to 20.
What is the best TPI for cutting metal?
Cutting thinner metals, including sheet metal, requires a finer cut. Use 18-24 TPI bi-metal blades. For thicker metals such as steel pipe, angle irons, or tubing, use 14-18 TPI bi-metal blades. For aluminum, an 8-10 TPI blade is best.
Is more TPI better?
Woodworkers quickly learn that the number of teeth-per-inch (TPI) on the blade has a big impact on the quality of a cut. The general rule of thumb is “the more TPI, the smoother the cut.” The true answer, however, is just a little more complicated than that, as you’ll learn once you understand how saw teeth work.
What saw blade makes the smoothest cut?
The 44-tooth blade (left) makes a smooth cut and is used for trim carpentry and cabinet making. The coarse 24-tooth blade (right) cuts quicker and is used for rough carpentry work.
What TPI should I use?
A coarse tooth blade (2, 3 TPI) should be used for resawing wood and cutting thicker stock up to 8″. A fine toothed blade (18 to 32 TPI) should be used for thinner metals and plastics under 1/4″. For general cutting of 3/4″ wood 4 TPI will provide a fast cut and 14 TPI will cut slow, but leave a smoother finish.
What is the best TPI for cutting wood?
If you’re looking to cut wood or other soft materials, you’ll need a blade with a TPI of 6 up to 20. For harder materials like metal, a TPI between 14 up to 36 is more suitable. You may also read,
What saw has the highest TPI?
A coping saw is a good example of a saw with more teeth per inch. Coping saws can have up to 32 TPI, making them ideal for slow yet very precise cutting when a neat finish and a controlled cut is more important than fast sawing. Check the answer of
Is more teeth on a saw blade better?
The number of teeth on the blade helps determine the speed, type and finish of the cut. Blades with fewer teeth cut faster, but those with more teeth create a finer finish. Gullets between the teeth remove chips from the work pieces.
What cuts smoother a blade with a lot of small teeth or a blade with a few large teeth?
In general, blades with more teeth yield a smoother cut, and blades with fewer teeth remove material faster. Read:
What is the best blade to cut plywood?
Carbide tip blades work brilliantly with plywood sheets. These blades have a much higher teeth count and that helps give you a smoother cut, which is highly sought after in this situation.
What does TPI mean?
T.P.I. is the acronym of Threads Per Inch, which refers to 2.54 cm in the imperial system for bicycle tires. By means of TPI we can measure how many threads there are in a casing by counting the number of threads per inch.
What TPI is used to cut plastic?
For cutting 1⁄ 4 ” or thinner acrylic, use a 10–14-tpi (teeth per inch) blade. With thicker plastics, a 6–8-tpi blade works well.
Why does my circular saw burn the wood?
Pushing the stock through the saw too slowly is a common cause of saw blade burn. Sometimes a blade that feels dull might only be dirty. If wood pitch resins build up behind the teeth of the blade, the cutting speed will slow down, increasing the chances for burns.
Can I use a reciprocating saw to cut tree branches?
You can cut branches and limbs with a reciprocating saw. If your tree is small enough, you can cut a tree down. Bear in mind, these saws are ideal for cutting stationary material. If there’s a lot of give to your branch or limb, the saw may just shake it rather than cutting through it.
Can you cut plywood with a reciprocating saw?
Yes, you can cut wood with a reciprocating saw, along with a wide variety of materials. You can cut through plywood and plyboard with no problem using just a general purpose blade with your tool. You can also cut dimensional lumber and studs, too, along with the nails and screws.
