Reviews give Bosch the lead among portable table saws; they say the Bosch 4100 saws are the best ever, with a blade guard system plus a true riving knife to prevent kickback. The most full-featured table saw in the line, the Bosch 4100DG-09, includes a digital rip fence for extra precision. Reviews praise the Bosch 4100 table saws for accuracy, convenient scales, easy blade changes, onboard storage and dust control. The soft-start 15-amp motor has electronic torque control to regulate the output to match the workload. Owners love the wheeled Gravity-Rise stand that snaps open or folds flat in a single, lever-activated motion; earlier complaints about squishy pneumatic tires have been resolved, since the stand now comes with solid rubber tires. The only safety feature missing on this portable saw is the flesh-sensing blade brake found on the more expensive SawStop Contractor Saw (*Est. $1,600) .
Popular Mechanics tests, rates and ranks the Bosch 4100DG-09 in comparison with 10 other portable table saws. We found additional excellent comparison tests of the Bosch 4100 series in publications aimed at serious woodworkers and professional carpenters. The 2011 Taunton Tool Guide compares the Bosch 4100-09 (without the digital fence) with five other portable table saws, based on earlier tests plus an annual survey of readers of two Taunton Press publications: Fine Woodworking and Fine Homebuilding. A separate review in Fine Homebuilding tests the high-end Bosch 4100DG-09, comparing it with five other portable table saws with riving knives. Earlier reviews at Popular Woodworking, Tools of the Trade and Fine Woodworking provide professional tests of the Bosch 4100 series of table saws. We also found useful owner-written reviews at Lowes.com, Amazon.com, BoschTools.com and HomeDepot.com. Woodworker Tom Hintz provides a detailed, well-illustrated review, but notes no drawbacks.
The Bosch 4100DG-09 earns a perfect rating plus top ranking, based on tests of 11 portable table saws in this detailed, well-illustrated review. The Bosch is the only saw reviewed here that has an arbor lock. Editors also praise this saw for its accuracy, power and sophisticated yet user-friendly design. Editors call the Bosch "superbly designed and detailed," criticizing only the way a pop-up tab can interfere with the fence when the table is unlocked.
Review: Portable Table Saws: We Test 11 to Find the Best, Roy Berendsohn, Feb. 2012
The handful of owners reviewing the top-of-the-line Bosch 4100DG-09 table saw here are enthusiastic. One owner says "The German engineering put into this tool makes the perfect cuts, the stand is fantastic." More than a dozen owners rate and review the less expensive Bosch 4100-09 table saw, which lacks the digital rip fence, but most of those reviews are copied from BoschTools.com.

3. Taunton's 2011 Tool Guide
The Bosch 4100-09 portable table saw -- identical to the 4100DG-09 but without the digital rip fence -- earns both an Editors' Choice award and top ranking in an annual survey of readers of Fine Woodworking and Fine Homebuilding. Editors praise the Bosch as "accurate, smooth and powerful," based on objective tests comparing it with five other portable table saws.

4. Fine Homebuilding
Jobsite carpenter Ireton tests the Bosch 4100DG-09 in comparison with four other 15-amp portable table saws that have riving knives. He takes pains to investigate reports of problems with the bearings in the motor, concluding that this was an early problem that Bosch has probably resolved. The Bosch earns praise for its blade guard system -- an easily positioned riving knife plus good visibility when the blade guard is down. This saw is also judged the easiest to set up, but then the crossbar gets in the way and is judged a trip hazard. The pneumatic tires and digital rip fence have both pros and cons. Overall, the Bosch ranks in the middle but is judged a good buy "if you want a big saw that sets up easily."

5. Popular Woodworking
The Bosch 4100 earns top ranking in a comparison against four other benchtop table saws (also equipped with riving knives) based on tests of accuracy and power, plus evaluations of ease of use. The Bosch is by far the quietest (though 93 decibels still requires hearing protection) and has an arbor lock to make blade changing easy. Dust collection is good, accuracy excellent without adjustments necessary, and all operations smooth.

6. Tools of the Trade
This review gives second place to the Bosch 4100DG-09, with praise for its safety features and arbor lock. The digital fence gauge is judged "a bit fussy" for jobsite work by a crew, but fine for work by one person. The stand is judged easy to roll around but hard to unfold.

This detailed single-product review by a frequent contributor to Fine Woodworking magazine includes photos of the new blade guard system on the Bosch 4100 series, as well as of the digital rip fence.

8. Fine Woodworking
This brief review reports that the Bosch 4100DG-09 saw handles 1.75-inch hard maple nearly as well as 0.75-inch plywood, and praises the saw for easy blade changes and an exceptional blade guard system that includes a riving knife. The only drawback is the "sticky, somewhat clunky" blade-lock lever.
Review: Portable Saw Fits the Bill in a Small Woodworking Shop, Anissa Kapsales, April 2008
More than 40 owners review the Bosch 4100-09 table saw here (identical to the 4100DG-09 except for the digital fence). Most praise the gravity-rise stand and the saw's accuracy, but a few report problems with the motor burning out and/or with Bosch customer service.
Review: Bosch 15-Amp 10" Table Saw Model #4100-09, Contributors to Lowes.com
More than 30 owners reviewing the Bosch 4100DG-09 portable table saw give it mostly rave reviews except for the digital fence, which quite a few owners deem more a problem than an asset.
Review: Bosch 4100DG-09 10-Inch Worksite Table Saw, Contributors to Amazon.com
About a dozen owners review the Bosch 4100-09 here, most very pleased with its accuracy and ease of transport and setup. The size earns mixed reviews, since the saw takes up space and can be hard to fit through doorways. The pneumatic tires also earn some criticism.
