The integrated blade carries an electrical signal. Once it comes in contact with human skin, the signal changes because of the skin’s conductivity and the blade immediately stop. Although some people don’t like the process of resetting the blade, it’s quite easy, and it takes only a couple of minutes. If you think about it, it’s better to hassle by resetting the blade for five or six minutes instead of losing a few fingers.
If you're currently looking for a cabinet table saw and it's the first time you actually need to buy one, then you should know that they come in a wide range of types, from the larger contractor saws to the portable table saws that most people seem to own. However, buying the right model for you depends on your needs and how you're going to use it.
To get the feel of the cut, we used a two man team to feed from one end of the saw and catch on the other. This helped us reduce the friction that comes from one person trying to hold a board flush against the fence while also keeping downward pressure to keep it level on the table. There was definitely some hesitation at the beginning of each cut that was alleviated once the board was received by the second man on the other side. It was during this middle section that the table/fence friction was at its lowest point and we made our determinations about each saw’s power and cutting speed.
If the blade you purchase has a .092” kerf (i.e. Irwin Marathon 80T, FreudLU83R010) you will most likely have issues with binding on the back end of the cut. To be safe, find a blade that has a kerf of around .098” (i.e. Freud Avanti TK905 50T) and this should take care of the problem. You should also take note that every blade Bosch makes should also work with the Bosch 4100-09.
Their 15-amp, 120-volt motors cut with greater ease than a circ saw, although they can bog down if fed thick hardwood too quickly. The cabinets are typically plastic, with cast-aluminum tops and extruded-aluminum fences. In these models, the motors are supported by trunnions mounted to the underside of the table. The resulting vibration reduces accuracy. These trunnions are usually made of lightweight steel or aluminum, which are susceptible to wear. And because these saws are small, cutting full-size sheets of plywood or MDF isn't a good idea unless the sheet is supported by a table extension.
Blade guards are an important safety device and should never be removed from the saw. You want to find one that rises up parallel to the table so it is always on top of the material you are working with. The purpose of this blade guard is to protect you from the spinning blade. While some woodworkers find them annoying, the safety they provide is well worth the inconvenience.
There are a few nice conveniences which we don’t always see on affordable units like this. The Grizzly has a built-in miter guide, made from cast iron, which slides easily in the worktop. The left-tilting blade is coordinated with a digital display, which gives you an accurate, real-time readout on your bevel angle as you cut! The motor has a starting amperage of 13, which is safer for your breakers than 15 amp models. There’s a standard 4” dust collection port, and
The machine has a more conventional rip fence/rail arrangement. The right half of the rail assembly folds out so the saw can achieve its full 30″ of rip capacity — wider than any other model here — but the fence would not slide smoothly over the rails without catching on the hinge joint. While the rip fence did maintain its locked settings, it lacks the heft and build quality of the competition.
