Bosch hammer drill9/5/2023 ![]() Bosch’s T Vario-Lock positioning also lets you rotate and lock the chisel to get the exact bite you need. One of my favorite features of this tool is the fatigue-reducing auto lock-on, which eliminates the need to actively keep the trigger depressed. It’s a nice feature to have, I suppose, but you will likely find one or two speeds that you use the majority of the time. SDS-Max Corded Rotary Hammer Drill with Handle, Case, Bonus SDS-Max, Spline Chiseling Dust Attachment. Just used a Bosch SDS max hammer drill model 11240 (360 for hammer drill on. I use one speed for chipping and one for drilling. Hex Hammer Steel Visit the BOSCH Store 38 ratings 6497 FREE Returns. In practice, however, I don’t change the speed very often. Visit tool retailers and actually feel different tools with dif- Makita 's lightweight hammer drill/ driver is powered by NiMH batteries, which have twice. The 15 amp motor has an absolute speed dial with six positions and provides up to 14.1 foot-pounds of impact energy which, coupled with the weight, is an impressive power-to-weight ratio. I even managed to bend a bit – when it’s in your hands, you know you’ve harnessed some power in the Bosch RH1255VC 2-inch SDS-Max rotary hammer. But be warned: the torque on this tool is so powerful that improper use can still result in violent wrenching. Bosch Active Response technology is the clutch system that is designed to prevent violent wrenching when jams or snags occur. ![]() Generally, when new tools are introduced, I like them to be lighter because lighter often makes the job easier.Ī danger of rotary hammers is snags – that is, the bit gets snagged on rebar – and it can injure wrists, arms, and shoulders. Bosch addressed this by bringing the RH1255VC in under 27 pounds and using a clever decoupled main handle with a tuned mass damper integrated into the aluminum cover. If you’ve used a rotary hammer for more than five minutes, you know the weight and vibration of the tool can quickly result in fatigue. I also used it on another jobsite where I drilled for rebar installation. That could be good or bad – this kind of tool needs the heft to get the jobs done, but it can’t be so heavy that it’s exhausting. I took the Bosch RH1255VC to a paver driveway job where I had to remove an 8-inch thick stoop (in fact, I used the power cutter reviewed in the link above for that job as well). It’s certainly beefier than a chipping hammer you might pick up at a big box home improvement store, but it looks like the alpha male even among larger rotary hammers. The first thing that struck me is the heavy-duty look of the Bosch RH1255VC. ![]() That’s where a tool like this Bosch rotary hammer comes in. But no matter how technical the job, very often I have to do some demolition or clearing work of some kind. You may have read my Makita MM4 4-Stroke Power Cutter review where, among other stonework, we made large concrete radius tie beams on a new home. I’ve been a mason for 30 years, and I think I’ve done it all – laid block, stone, paver driveways, built fireplaces, waterfalls, outdoor kitchens with stonework, and other artistic projects.
