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.
The thing you might not like about it is the non-flat table top. Many people find this downside as quite a burden, especially if you’re processing perfectly flat wood. Also, the protective coating on the top side of this model is pretty subpar. In fact, it barely protects anything. Consequently, it will peel off quite quickly. As far as the price goes, it’s okay, but it could have been a bit cheaper.
Like the Grizzly, the Jet has a standard 4” dust port coming out of the cabinet, and a 220V wiring box for you to attach a power cord. The Jet is also a more shop-friendly tool, since it has much better dust collection. That’s thanks to a fully-shrouded blade and a guard which handily deflects sawdust into the vacuum channel, rather than off to the side of the table.
It’s highly portable. Even though the whole body feels sturdier than the Dewalt’s, it’s still relatively light, at just about 60 pounds. There are handles in both the top and bottom edges of the machine, for easy lifting, and once you’ve got the saw fixed to the base, you won’t have to lift it on your own except for when you’re loading it in the back of the truck/van.
It’s built heavy. Like our other recommendations, this one has a machined cast iron worktop, and all-steel cabinet. There are miter slots cut into the worktop, and the bevel and height adjustments are via machined metal flywheels that are calibrated and balanced with the trunnion. We especially love the internal gearwork for raising the motor, which has precise torque bolts and a gas assist to make all your adjustments both smooth and easy. The cabinet is powdered steel for added durability, and the Professional woodworkers and amateur reviewers alike said they were above impressed with the overall build quality. This one feels as premium to use as you’d expect from the pricetag.
Finally, make sure you know your long-term options when it comes to maintenance, repairs, or replacements. Check the warranty coverage on your portable unit. Read the fine print, checking whether you’ll be paying for repairs under warranty, or whether the company will be footing the bill. Some manufacturers cover repairs, but not return shipping. Others force you to bring your unit to an authorized dealer, which can be difficult in some parts of the country.
We evaluated the flatness of the table by measuring the flatness by placing the edge of a precision ground flat bar across the table and placed feeler gauges in any gaps to measure any difference between the ground bar and the table. TBB took measurements in four directions. As the operator faces the saw, we measured the flatness at the arbor from front-to-rear; we measured the left-to right flatness at the arbor; we measured the flatness from the upper left-to-lower right table corners; and, finally, we measured the upper right-to-lower left flatness between the corners.
