When you purchase your table saw, more than likely it will have standard 10” carbide tipped blade that is good for general purpose use. This blade is capable of cross cutting a 4 x 4. If you replace it with a 40 tooth combination blade you will improve the quality of your cuts significantly and more than likely be much happier with the blade overall. You can get specialty blades also if you are going to be cutting other materials as well.
There are a lot of obvious reasons why the Skilsaw Portable Worm Drive Table Saw is top quality. Foremost, it is the first worm drive table, therefore, all other similar products are just based on this portable table saw. The Skilsaw is a brass-geared worm drive table saw that provides top power for maximum torque with its 5 HP dual-field motor for improved cutting speed. The selling point is its portability and compact design which makes it transportable anywhere.
Belt drive table saw motors run on a pulley system, most of the time some power is lost through this system, but belt drive blades can cut through thicker timber and hardwoods. They can produce power of around 3 to 5HP and thanks to the motor being mounted further away from the blade with belt drive, the motor will last longer as less dust will get into the motor. One thing to consider though is that belt drive will be in general more expensive and are normally found on heavy cabinet type saws, so this must be considered when working out your budget.
