Review: Bosch 4100 Table Saw (10″)

The Bosch 4100 Table Saw is a great choice for a reliable, durable portable table saw. This is a great choice for home or work site use. This saw is light and feels like a portable saw, but it has a lot of little quality touches that you’d have a hard time finding on other saws in the same price range. This is a great table saw choice for those that want contractor-quality performance and feel in a portable saw.

Bosch 4100 table sawThe Bosch 4100 is pretty much identical to one of it’s brothers, the Bosch 4100-09, except the 4100-09 comes with a gravity rise stand. If you need a stand too, take a look at the Bosch 4100-09 instead.

Now let’s get into the details. Read on to learn more.

The Bosch 4100 table saw has all of the following major components:

  • A 10 inch blade that cuts through many materials with ease, a no-load speed of 3,650 RPM.
  • The Square Lock Rip fence which helps support one handed cutting and can be adjusted quickly and easily.
  • A Smart Guard, a nice safety feature that protects you from the blade.
  • A T-slot Miter Gauge that can be used to assist with cross cutting and other similar types of cuts.

There is a on-board storage for the miter, rip fence, blade guard and anti-kickback pawls. This might seem trivial but it’s very handy if you are going to be porting this saw around a lot. The accessories will always be on-hand since they can be stored in the saw.

The fence and miter saw are higher quality than you would expect, especially when compared to some of the other similar saws in this price range. Out of the box it takes under 15 minutes to assemble, and many buyers say that this saw is pretty square after set up as well. This is one of the easier portable table saws to get running out of the box.

Cutting Table & Rip Fence

The cutting table is very smooth and surprisingly spacious for this size of a saw. The cutting table dimensions are 29″ x 21.5″. You can cut sheets of wood that are up to 25 inches in width.

The Square Lock rip fence is accurate and works nicely. It can be adjusted with ease and can be removed and stored in the saw when not in use. When tightening the square to lock the fence down it does not lose accuracy either, another big plus as far as efficiency and accuracy are concerned.

The Motor & Power

The Bosch 4100 saw delivers 4 horsepower from a 15 amp motor. It has a no-load rpm of 3,650.

In terms of noise, many people who buy this saw say it’s more quiet than the older saws they replaced with this one. This is a table saw though, so it will still be loud, and ear protection is always a good idea.

This saw also uses Constant Response Technology and Soft Start technology from Bosch. What does this mean? The speed of the saw slowly ramps up when the saw is started so that the starting process is smooth and less jarring. Also, this technology helps maintain saw speeds when under high cutting load pressure. This equals a very smooth and efficient cutting experience, especially when paired with a high-quality blade.

Many Safety Features

This saw also employs a Smart Guard System which is actually a combination of 3 separate safety features.Bosch 4100 table saw safety featuresAll of these features can be removed independently of each other, allowing you more flexibility for more demanding cutting applications.

  • A riving knife – this keeps the materials that you are cutting from pinching on the blade, and this feature alone will greatly reduce kickback possibilities
  • A blade guard – this protects the top side of the blade and keeps it out of the open and protects your hands mostly
  • Anti-kickback pawls – this feature helps pin the materials you are cutting to the table, and further helps to reduce kickback

Another interesting note: Riving knives are now required as a standard table saw feature by Underwriters Labs. That’s why you are seeing them on all the new table saw models since 2009.

The Bosch 4100 is a very safe table saw, and these three features are the main reason for that.

These safety features are also what makes this saw an ideal choice if you do a lot of one-handed cutting or will be using the saw by yourself, without a cutting partner.

The Saw Blade

The saw blade that is packaged with the Bosch 4100 is pretty good, but it’s definitely not a top-end blade. If you are a weekend warrior type, or if you will be using the saw occasionally, you may be able to get by with the included blade. In this scenario, we would at least suggest trying the included blade first before spending the money on an upgrade if money is an issue. You may be pleasantly surprised.

You may want to upgrade to more high-end blade though, and if you want the ultimate cutting experience with this saw a blade upgrade is an easy choice.

Also keep in mind that you will need to get blades that have a kerf that is slightly larger than the riving knife.

The riving knife has a width of .091″, it may be best to try to get a blade that has a kerf of .098″ or higher to prevent wood from binding on the riving knife and fence when cutting.

Replacing the blade really couldn’t get any easier as well. When we wanted to put a different blade on this saw, the arbor lock system made it easy to remove the existing blade and put the new one on with little trouble. This was refreshing.

Cutting Dadoes

If you want to cut dadoes with the Bosch 4100 table saw, you will need to get the Bosch TS1007 Dado Insert. It’s a cheap accessory but it does not come with the 4100 out of the box, so keep that in mind.

In order to get a dado stack to fit, you will need to shift around the arbor washers by removing the inner washer and using the out washer on the inner part of the arbor. Check out our notes regarding making a stack dado set fit on the Bosch 4100 and 4100-09 table saws.

Useful Accessory: Left Side Support Extension

Many times the size of the cutting table on a portable table saw can be an issue, even though portability is desired. The cutting table can easily be extended (and cheaply for that matter) buy using this left side support extension. It adds 12 inches to the cutting table for a total of 52 inches.

We take a closer look at this accessory in our Bosch TS1003 support extension overview. Check it out if you want to get some more details.


This saw is billed as a portable table saw, which it is. It’s small footprint makes it ideal for table top use or if you need to move it around a lot it’s smaller size is really handy. However, at 79 pounds, it can be a bit tough for some people to move around by themselves.

Many people who buy the Bosch 4100 for it’s portability often find that they also actually need the Gravity Rise stand offered by Bosch to get maximum portability for situations where only one person will be moving the saw, rather than two people.

If you are interested in portability and like the sound of having a folding, rolling stand for the Bosch 4100, then we recommend you take a look at the Bosch 4100-09 with Gravity Rise stand.


We really like how the Bosch 4100 portable table saw offers a very solid feel with no weak features. At it’s price, it’s a very good buy and it will give you quality cuts in a portable size. If you need something portable for home use or work use, we really have a hard time recommending other saws over this one. It’s just a quality tool. It rarely disappoints.

Where Can You Buy This Saw?

We would suggest checking out Amazon to see what the current pricing is. Last time I checked they had a really good price. They also have more user reviews if you want to get some more insight from other people who purchased this saw.
