Saws and Cutting tools Buying Guide - How to choose the right saws and cutting tools.
In general, a saw with more teeth per inch cuts slower but leaves a cleaner finish; a saw with less teeth per inch cuts faster but leaves a rougher finish. Besides, the more teeth per inch a saw has, the harder materials the saw can cut through.
Sawteeth are ground in three different angles so they are called triple ground teeth. A saw with triple ground teeth can provide smoother and more efficient cuts than a traditional saw with double ground teeth because it has sharper teeth and smoother gullets.
The teeth are hardened by means of wave impulses with a very high peak power and a special high frequency. The impulse-hardening teeth means sawteeth will stay sharper for longer.
As a general rule, a thicker blade is firmer so higher precision and better cutting performance can be expected; a thinner blade features its flexibility so it's better to choose a thin blade if you want flush cuts or thinner cuts.
