With a 4.0Ah Core18V battery, the Bosch 18V Compact Hammer Drill weighs 3.86 pounds. All in all, it’s a nice, tight design that ranks as one of the more compact ones, save for a couple of sub-compact models. Bosch keeps that in perspective with a design that’s 8.0″ tall without the battery ad 7.2″ long. The entire purpose of a compact tool is to be, well, compact. But hey, give credit where it’s due, right? Size and Weight Its ratings would be higher, save for Metabo HPT and DeWalt really skewing things with much higher torque and speed tests than the rest of the group. None of these results are particularly disappointing and it’s actually a pretty steady performance for Bosch. The Bosch GSB18V-535CN averaged 7.72 seconds to merit a 3rd place finish. We used a 1/4″ Bosch Daredevil Multipurpose Bit and timed how long it took it to drill down 3″. It averaged a very average 394 RPM with a 70% efficiency score.įinally, we tested the Bosch 18V Compact Hammer Drill in our concrete slab. Kicking it into low gear, chucked up a 1-1/2″ Milwaukee SwitchBlade Self-Feed bit to really see how the tool’s speed and torque work together. Holding 69% of its tested no-load speed, there are a few more drills working more efficiently and it has a healthy cushion ahead of Craftsman at the bottom. Again, it finished in the middle of the pack with an average of 1276 RPM in high speed. Next, we used the Bosch compact hammer drill with a 3/4″ Bosch Daredevil High-Speed Auger Bit to test its speed under load. Even though it’s right in there with other top-half hammer drills, Metabo HPT’s compact model put a big gap on everyone else at 312.0 in-lbs. The GSR18V-535CN produced 169.2 in-lbs of soft torque, which was enough to place it dead in the middle of the pack with a 5th-place finish.

If it does, the sensor cuts off power to the drill to keep it from trying to yank your wrist off your arm. The Bosch GSB18V-535CN also features Kickback Control in case the bit binds up. Of course, if you don’t care about the shiny, newfangled-ness of this modern convenience, you can avoid it altogether and still have a really nice compact hammer drill. Inserting the Connected module into the access point on the handle turns this drill into a smart tool, allowing you to inventory and track your tool, manage battery life, and customize your power settings via the free Bosch Toolbox app. What does set this hammer drill apart from other models in its class starts is its compatibility with the Bosch Connected system. Most of the compact hammer drills we tested had these features, and they don’t set the Bosch model apart by themselves.
