This is a work horse. I am using it to build out my basement. It pushes the bits through like butter. My only problem was that the depth guide moved with the vibration but it doesn’t affect my review. I like it a lot. The vibration was not bad either. My hands experienced no issues. It is a great tool, seems heavy duty, and was a good value for the money. Perfect!

Buen producto

Cumple con las especificaciones, ya está probado, ranura sin problemas.

Before this purchase we pulled up a bathroom floor and it took 3 days. We took the tile up in a much larger area in under an hour. it saved days of work. Got a special bit and it took the mortar off so our subfloor could be used for laminate which needs a flat floor for install. Worth the $300 we spent on the tool and bits.

Es una buena herramienta, se siente con mucha fuerza y para un uso casero creo que está hasta sobrado

Lo he utilizado durante tre meses para perforación sobre mampostería y una que otra ocasión en concreto, hasta el momento no se ha dañado (usándolo adecuadamente y aceitando las brocas), no se calienta y el impacto con el que perfora es bueno y rápido, no es pesado y tiene buen agarre.

A mi trabajo, me funciona perfectamente, es muy buena marca y tiene la potencia que necesito, lo encontré a muy buen precio. $3,200 aprox. Está excelente

Great, has straight hammer feature

Súper buena herramienta

Producto necesario en tu kit de herramientas; Solo considerar que se calienta un poco cuando el uso es constante, pero aún así cumple con creces su función.Dado que se trata de un Bulldog SDS Plus, sugiero adquirir también “la grasa de la marca” y un kit de brocas SDS PLUS de la marca y/o bien adquirir un adaptador de la marca para poder usar brocas convencionales; Ambas cosas no son costosas

Se lo regale a mi hermano y está encantado. No es muy pesado, es muy potente, asi que los trabajos se hacen rápido

I'm very happy with this tool. I purchased it to replace my corded hammer drill that's equipped with a regular Jacob's chuck.The Bosch rotary hammer drill is very easy to use. It is also much less tiring to use than my older corded hammer drill. It produces less vibrations and much less noise when drilling through concrete.Over the last few months, I have drilled hundreds of holes with this new tool and I have nothing bad to say about it. The carrying case is simple and well build (it's far from a pelican case, but it does the job). So far, the biggest holes I've drilled in concrete with this tool were 1/2"x8" for mechanical anchors. It felt like I was drilling through butter!I have also tried the hammer function to chip concrete around pipes going through floors. Again, this tool worked really well for that too. The trigger is sensitive enough to accurately control the chipping action blow by blow to not damage the pipes close to the chisel's tip.

(Review for "Bosch 11255VSR BULLDOG Xtreme 1-Inch SDS-plus D-Handle Rotary Hammer", Purchased on Amazon June 2013.)2-1/2 years later this tool has held up to the test of time, durability, and performance (and abuse!). It has so far easily chiseled through 600sqft of floor tile and thinset laid over concrete slab, broken apart portions of 4" concrete slab (after drilling holes into it first), and drilled many dozens of vertical holes into existing reinforced concrete foundation wall, ranging from 5/8" to 3/4" diameter holes down to 8" to 12" deep. As expected it has no problem with all of the various SDS-Plus bits and attachments, of which I have 6 different SDS-Plus concrete drilling bits, each 18" long, and 3 different chisel bits. The tool often gets covered in concrete dust after drilling yet does not impact performance and quick blast from an air compressors will easily clear the dust. I am impressed with its longterm durability, especially after weeks or sometimes months of no use while sitting in my toolboxes - it's been stored in my S.Texas garage or truck toolbox, exposed to S.Texas summer heat and humidity (but I've never allowed it to be directly exposed to wind-driven dirt, or to rain/water). I rarely use the case. [The case it ships with is terrific for storing the tool with its D-Handle and almost a dozen SDS-Plus bits (depending on length and tip), but it occupies too much space for my needs, and so it is stored in a mobile toolbox along with other power tools. The case is sturdy, of durable plastic, with good locking latches - I believe the case over time will not crack or become brittle as the plastic material appears to be the same as for other cases from Bosch, Dewalt, etc.] The metal bracket on the handle comes in extremely handy - pull the metal bracket out and the tool can be easily hung on any horizontal pipe, scaffold member, etc. - just like the Bosch Nail Guns. The tool's settings for forward-reverse (a slide switch) and for drill-combo-hammer (a dial) stays in place, and after more than a 100+ hours of (intermittent) use over 2-1/2 years, the dial and slide switch settings have never vibrated out of setting, unlike some other lesser (non-SDS) rotary hammers I've had. I have found that the reverse setting (counterclockwise rotation) is just as powerful as the forward (clockwise) rotation both in terms of speed and torque - an 18" long 3/4" diameter SDS-Plus drill bit will often get stuck on it's way to 8" to 12" deep, especially when it encounters rebar or some really hard stone aggregate...and as the tool description says, it disengages the torque when it detects the bit is stuck. Getting unstuck is as easy as throwing the hammer/drill into reverse. It almost instantly gets unstuck, ready to go at it again. The large red trigger (on/off) button on the handle has so far been great - I can fit 1-2 fingers to hold it down for those long drills into concrete (I have not complaints on the trigger-pull as I do on one of my handguns :)). The best part is that this trigger appears to accurately and proportionately control the variable speed rotation of the drill (in either forward or reverse) - you can go from zero to full speed rotation fast or control the drill/hammer speed as precisely as needed, which is fantastic when first starting off a drill bit. In my opinion, this SDS-Plus hammer-drill is powerful - with the right SDS-Plus concrete drill bit, most of the 8" to 12" deep holes in concrete take only several minutes. (IF you need a more powerful hammer-drill for concrete and hard stone, well...get the bigger cousin.) Bit changing is fantastic with the SDS-Plus format and the tool's quick-change chuck - the chuck is a solid design. Once the SDS-Plus bit is locked in, it doesn't come off or come loose, and the only times that it does is because the bit wasn't properly/fully inserted. The D-Handle is in my opinion adequately designed and does the job well - I've never removed it, always using the D-Handle on every use without a problem whatsoever. The only issue I have had is the depth gauge, but nothing worth dinging any stars from the core tool itself...whatever metal it's made of (aluminum?) is flimsy and it bends way too easily. Sure I can unbend it but it's a bother trying to really straighten it out. It is also short for my needs, although I think most users will be happy with it. [FYI - 18" long SDS-Plus drill bits have 4-6" of empty shank and the depth gauge is barely long enough when drilling down to only 6"-8". I have no comparisons to other hammer-drills of the SDS-Plus class so I do not have adequate perspective to share. I bought the tool based on the reviews on Amazon and research of SDS, SDS-Plus, and SDS-Max hammer drills. Even with my own [limited] abuse, I think this is one of the best quality, most powerful and most durable power tools I will ever own. In a few weeks, I'll be using this tool to pound 5/8" and 3/4" by 8 foot long ground rods into rocky soil...I have no hesitation that it'll do a great job fast.
