#3 Cutting Performance
The 80-tooth blade, with its decreased vibration and smooth cutting, provides a reliable performance suitable for a wide range of materials.
Alternatively, the 100-tooth blade is known for its efficient carbide, allowing clean cuts. But it may be slightly more fragile compared to the 80-tooth blade.
The increased number of teeth on the 100-tooth blade allows for smoother edges on your cuts than on 80-tooth blades. This is ideal for projects that require a polished finish and reduces the need for additional sanding or smoothing.
#4 Chipping and Splintering
Imagine your material being shredded and splintered into a thousand pieces, leaving behind a jagged mess that resembles a tornado aftermath. This is the unfortunate result you may experience when using an 80-tooth blade.
However, with a 100-tooth blade, you can expect significantly improved chipping and splintering. Here are some reasons why the 100-tooth blade is superior over 80-tooth:
- Finer teeth: The 100-tooth blade has more teeth per inch than an 80-tooth blade, allowing for a smoother and cleaner cut. This reduces the likelihood of chipping and splintering.
- Specialized design: The 100-tooth blade is designed for clean cutting compared to 80-tooth blade. It has a sharper edge and a higher tooth count, enabling it to slice through materials with precision and minimal damage.
#5 Price Range
Pricing can make a significant difference when choosing the right blade for your needs. While an 80-tooth blade may be cheaper, it may produce more tear-out and rougher cuts, leading to increased chipping and splintering in certain materials.
Meanwhile, a 100-tooth blade minimizes chipping and splintering, delivering cleaner and smoother cuts, especially in delicate materials. This improved quality may justify the higher price of a 100-tooth blade, especially if you frequently work with delicate materials or require precise cuts.
How Does a Miter Saw Blade’s TPI Affect Cutting?
Feel the exhilaration as you witness the smooth and precise cuts made by a miter saw blade, which has a high TPI, effortlessly gliding through the wood. A miter saw blade’s TPI, or teeth per inch, greatly affects its cutting performance. Here’s how:
Efficient Cross-Cuts
Miter saw blades with a higher TPI count, such as a 100-tooth blade, excel at making clean cross-cuts on wood perpendicular to the grain. The smaller teeth and greater TPI allow for finer, smoother cuts.
Finer Finish
The high TPI count of a 100-tooth miter saw blade creates smaller, more numerous teeth. This results in a finer finish on the cut surface, reducing the need for additional sanding or finishing work.
Reduced Tear-out
Many small teeth on a high TPI blade minimize tear-out or splintering on the wood surface, leaving behind clean and precise cuts.
Slower Feed Rate
A miter saw blade with a low TPI requires a higher feed rate due to the lower tooth count. This allows the teeth to engage effectively with the wood, producing accurate and fast cuts.
Compatibility with Thin Materials
A 100-tooth miter saw blade with higher TPI is ideal for cutting thin materials, as the small teeth provide excellent control and prevent damage.
Is it beneficial to have more saw teeth on a miter saw blade?
Having more teeth on a miter saw blade significantly enhances its cutting precision and the quality of the finished result. When a miter saw blade has more teeth, each tooth takes smaller bites out of the material, resulting in a smoother and cleaner cut.
This is especially important when working with delicate or expensive materials that require high precision. The increased number of teeth also reduces the risk of tear-out, which can occur when the blade tears the material fibers as it cuts.
Also, a higher tooth count allows for more efficient chip removal, preventing clogging and overheating of the blade. Therefore, if you prioritize a clean and accurate cut, opting for a miter saw blade with more teeth is the way to go.
What is an 80-tooth saw blade used for?
If you want your cuts to be as smooth as butter, an 80-tooth saw blade is like adding a dash of magic to your woodworking projects. With its finely crafted teeth, this blade is designed to deliver clean and precise cuts on various materials.
