Bosch 4100-09 Table Saw Review (2026): Still Worth Buying After All These Years?

By Finlay Connolly

So You’re Looking at the Bosch 4100-09

This saw has been around for years, and it still comes up all the time when people ask for a good jobsite table saw. It’s not new or flashy. It’s the kind of saw that shows up in garage shops, on jobsites, and in small basement setups where there’s no room for a big cabinet saw.

People who’ve owned this saw for years keep saying the same few things, good and bad, over and over on woodworking forums. That kind of repeated feedback is worth more than a shiny five-star review written after one afternoon with the saw. This review pulls from what actual owners have said after using it for months and years, not just what’s printed on the box.

What This Saw Actually Is

The Bosch 4100-09 is a portable table saw with a folding stand, built for people who need to move the saw around, not leave it bolted in one spot forever. It comes with Bosch’s Gravity-Rise stand, which folds down and rolls on wheels, so one person can set it up or pack it away without help.

It runs a 15-amp motor rated at 4 horsepower, spins the blade around 3,650 RPM, and has a 25-inch rip capacity. That last number matters more than it sounds like it should. Anything under 24 inches of rip capacity means you can’t cut a full sheet of plywood in half. This saw clears that mark, which is a big part of why it’s stayed popular for so long.

Quick Verdict

Buy it if: you need a powerful, portable saw that can handle full sheets of plywood, and you’re willing to spend a little time getting the fence dialed in properly.

Skip it if: fence accuracy right out of the box matters more to you than anything else, or you want the quietest saw in this class.

Short version: this saw cuts well and handles big sheets of material without a fuss. The fence is the one part that comes up as a complaint again and again, but most owners who stick with it say it holds steady once it’s properly set.

What Owners Keep Saying, Good and Bad

The single most repeated complaint across different woodworking forums is the fence. One long-time owner called it painful to use. Another said it was wobbly and hard to adjust at first. A different owner had the fence twist slightly out of square whenever it was locked down, which is a real problem if you’re trying to make an accurate cut. This isn’t one unlucky buyer. It shows up again and again, from different people, on different forums, over more than a decade.

At the same time, plenty of owners say the fence stops being a problem once you take the time to set it up right. One woodworker checked his fence and blade alignment after almost three years of use with a dial indicator and found it was still holding the factory settings. Another mentioned having to adjust the fence scale twice early on, and after that it stayed accurate. The pattern seems to be: rough right out of the box, but fine once you’ve spent a little time truing it up.

On cutting performance, the reviews are a lot more consistent. Owners describe it cutting cleanly through plywood, particle board, and MDF without bogging down, and handling hardwood without much trouble either. One owner specifically mentioned using it for laminate countertops and mortise and tenon joinery, saying it cut everything they needed with good precision. Noise comes up as a fair complaint too. More than one owner has called it loud, though most seem to accept that as just how this type of motor sounds.

A Few Things Nobody Tells You Until You Own One

There’s a block of styrofoam packed under the motor for shipping, and the instructions warn you to remove it before raising or lowering the blade. Skip that step and you risk damaging the height adjustment mechanism. It sounds obvious once you know, but it’s the kind of thing that’s easy to miss if you’re rushing through setup.

The riving knife lever is another spot worth being careful with. One owner didn’t bother adjusting a tight lever early on and ended up cracking it, which turned into a real repair cost since it’s only replaceable as a full unit. A five-minute check when the saw is new can save you an annoying and avoidable repair bill later.

Dust collection isn’t great out of the box, but it’s fixable. A couple of owners mentioned using a flexible sleeve adapter to get a tighter connection between the saw’s dust port and a shop vac hose, which made a noticeable difference. If dust collection matters to your shop setup, it’s worth checking our Best Shop Vac for Dust Collection guide before assuming any vacuum you already own will do the job well.

Real-World Use

For garage shops where a car also needs to fit, or basement shops with limited space, this saw comes up constantly as the practical answer. It handles full sheets of plywood, which a smaller benchtop saw can’t, while still folding down small enough to roll into a corner when you’re done. It’s also a common pick as a backup or secondary saw for people who already own a bigger cabinet saw but want something portable for jobsite work or for cutting large sheet goods without hauling them into a shop.

It’s not trying to be a cabinet saw, and owners who understand that going in tend to be happier with it. It’s a saw for portable, get-it-done work, not for the kind of fine furniture joinery where you need everything dead accurate straight out of the box with zero adjustment.

Common Mistakes and Setup Issues

• Raising or lowering the blade before removing the styrofoam shipping block under the motor
• Forcing a tight riving knife lever instead of adjusting it properly, risking a crack in a part that’s only replaceable as a full unit
• Assuming the fence will be dead accurate out of the box without checking and adjusting it first
• Not upgrading the dust port connection, then being disappointed by how much dust escapes during a cut
• Expecting cabinet-saw-level rigidity from a portable saw with an aluminum top instead of cast iron
• Skipping the blade upgrade. The stock blade works fine at first but dulls faster than most owners expect

How It Compares

Bosch 4100-09 vs. DeWalt DWE7491RS

These two get compared constantly, since they’re priced close together and both aim at the same jobsite buyer. Owners who’ve used both tend to give the fence edge to DeWalt, describing it as more repeatable and easier to keep aligned, partly thanks to a redesigned riving knife and guard setup with better dust collection. If fence accuracy out of the box is your top priority, our DeWalt DWE7491RS Table Saw Review covers exactly how that fence holds up in more detail.

Bosch 4100-09 vs. Ridgid R4512

The Ridgid is a heavier, stationary-style saw with a cast iron top and a bigger induction motor, while the Bosch is lighter, more portable, and easier to move around by yourself. Woodworkers comparing the two generally say the Ridgid feels more like a small cabinet saw, while the Bosch feels more like a true jobsite saw you can fold up and carry. Our Ridgid Table Saw page covers more on how that model performs if portability matters less to you than raw stability.

Who Should Buy This Saw

• Contractors and remodelers who need a powerful saw that folds down and travels easily between jobs
• Garage or basement woodworkers who need to cut full plywood sheets but don’t have room for a full-size cabinet saw
• Anyone who already owns a bigger stationary saw and wants a reliable second saw for onsite or rough-cutting work

Skip it if fence precision straight out of the box is non-negotiable for your work, or if you’re building fine furniture where every setting needs to be dead accurate with zero adjustment. In that case, it’s worth browsing our Best Portable Table Saws for the Money roundup for other options in the same class.

Final Thoughts

The Bosch 4100-09 has stuck around for a reason. It cuts cleanly, handles full sheets of plywood, and folds up small enough to store or transport without much trouble. The fence is the one part that consistently frustrates new owners, but the same forums full of complaints are also full of people who fixed it once, checked it, and never had a problem again after that. Go in expecting to spend a little time truing up the fence when it’s new, watch out for that styrofoam shipping block and the riving knife lever, and this saw will handle years of regular use without much drama.
