Top Quality, Task Specific
By Keith Arnett
My previous hammer drill finally died, so I turned to Rockwell based on my experience with a previous Rockwell drill I obtained almost 40 years ago - used. That drill finally gave up the ghost a while back (the commutator contacts finally wore out). I fully expect the RK3137K to give similar service (which means it will likely outlast me).This is a truly heavy-duty, professional piece of equipment, built of quality material for long-lasting service. It is definitely optimized for use as a hammer drill -- the drill and cord weigh in at about 5-1/2 pounds, without the handle, depth rod, or bit. If you have thoughts of using this as a general purpose utility drill as well as a hammer drill, don't plan on a lot of one-handed use, unless you've been hanging out at the gym.Ergonomically, the unit is well designed and fits the hand well. The rubberized rear grip is a nice touch. The unit comes with its own carrying case that contains the drill, a removable handle, a depth gauge rod, and a set of six masonry bits.Controls include a variable-speed trigger switch, a switch lock (for full speed only), a forward/reverse toggle switch just above the trigger, and a rotary mode/hammer mode switch on the top of the unit. It provides plenty of power and torque. The attached 10 foot (ungrounded) cord is convenient and means you can dispense with an extension cord in some cases. The 1/2" keyed chuck works smoothly and grips well.Naturally, performance is as much dependent on the masonry bit as on the drill itself, but this unit, matched with a good bit, certainly performs at the top of the scale.I have only two small quibbles with the RK3137K. First, I'm disappointed with the chuck key retainer that is molded into the power cord strain relief. Technically, it works OK when you get used to it, but I have doubts that it will last very long, given the fact that you have to force the key into and out of it every time you want to use it. Also, if you drop the key, it's gone -- you have to climb down from the ladder or scratch around in the grass to find it. Plus, it is very easy to get distracted, set the key down somewhere and then wander on to the next work site -- only to scratch your head and wonder where you left the key. Some designer's great idea, I'm sure, but a standard cord-mounted key retainer would have been a better choice. Fortunately, it is easily remedied with one from the hardware store.Secondly, although the forward/reverse switch is conventionally located above the trigger switch, it seems prone to accidental engagement for whatever reason. It may have to do with the weight of the drill, or perhaps the size of the tab on the switch. At any rate, I have had other drills with this layout but haven't experienced this on them.As for enhancements -- this drill pretty much covers all the bases, but one thing I would like to see added is a mechanism for enabling a low-speed/high torque mode. But again, it is optimized for use as a hammer drill, and I am very happy with it, and would recommend it to anyone.

Works great
By V.G.
Worked so much better and faster than a standard drill for concrete. I really like having the adjustable handle and depth gauge too. It's reasonably comfortable to use and seems quite durable, although only time will tell.

I purchgase this hammer drill to drill through an 8" concrete wall. The drill did it's job fast and easy after I purchased a quality 12" Titanium concrete drill bit. This drill is very strong and you must use a quality bit or your standard bits will be destroyed.Great Product and Great Price
