Got this Amazon Denali 20V Cordless Rotary Hammer Kit for light duty use around a small homestead. Mostly boring holes to break rock, pin rock down with rebar, pin stuff to rock with rebar or bolts, or bore through masonry. Would like to use this for SDS chisel bits too but can't... Design is good, compact, light weight, somewhat atypical of rotary hammer drills, but it only has two modes, hammer-drill mode and drill mode, it is missing a hammer-only mode, which means it cannot make use of SDS chisel bits. This appears to be a rebranded Skil RH170202, same specs, slightly different casing, but without the Skil PWRCORE 20 battery & rapid charger features. Build quality is good, this feels like a well made tool, nice durable casing, nice grip surfaces. Functionality is decent for light duty home DIY usage. This is easily albeit slowly able to drill 1/2in by 3in holes in rock and masonry, several holes per battery charge, runtime is around 20 minutes per charge, anything smaller is easier, but I haven't tried anything larger than 1/2in. For drilling holes to run cables through concrete, brick, block, or rock, this will work well, even in light duty professional use it'll do alright as long as a spare battery & charger are available. This is not so good at perforating rock to break it, corded and brushless tools can drill holes much faster (4 or more times faster) and many more holes per charge. This is the first rotary hammer drill I've used which does not have a hammer-only mode, which is awkward, I didn't know these were even made. Price point is good compared to other name-brand tools, and this is higher quality than stuff from similarly priced Chinese generic brands, even if they offer better performance the service life will be shorter, which is reflected in Amazon's warranty. The rest of the Denali platform is good for similar light duty home DIY & hobbyist use, here are the tools I have: - Angle Grinder, nice compact mid-range grinder with thumb switch, nice side handle back position & wrench in the side handle, good for small tasks, but power hungry, comes with only 1x 4Ah battery, runtime is 15min with 100min recharge (4Ah batteries are overpriced, as of this writing a 2nd 4Ah battery by itself is $20 less than a 2nd angle grinder kit). - Impact Driver, 1/4in bit driver, good mid-range power, handles 10x3.5in torx deck screws well and anything smaller easily, but struggles with bigger stuff, not intended to drive larger sockets but can probably take lug nuts off a smaller car. This includes an extra battery. - Hammer Drill, good mid-size drill-driver, weak hammer action also handles 10x3.5in torx deck screws but slower than the impact driver, easily handles anything smaller, struggles with anything bigger. This includes an extra battery. - Jig Saw, nice little saw, as powerful as 40 year old corded jig saws I've repaired and used on DIY home remodeling projects. - Sander, nice 5in sander, as powerful as a couple ~25 year old corded palm sanders I have. - Oscillating Multi-Tool, nice tool, but the blade locking hex bolt + hex wrench is clunky, other brands use various styles of toolless chuck. With the Hammer Drill and Impact Driver each providing two batteries, either one is a good entry point into this tool platform (or both is great), and provides the spare batteries & charger to use any of these tools all day at a casual DIY pace, except for this power hungry angle grinder. With more batteries some of these tools can do alright in light duty professional usage. Not all of the Denali tools use weaker inefficient brushed motors, I narrowly missed getting the 12in chainsaw with a brushless motor and a 4Ah battery, should be nice, and goes well with an angle grinder. Cross compatibility with Skil PWRCORE 20 batteries & rapid charger is nice and pushes many of these tools over to lower tier professional grade performance, especially with the bonus torque from a 5Ah battery. Overall, 4 stars, decent light duty rotary hammer drill.
