Customer Review: Everything I expected and more
Summary: 5 Stars
I am putting in a 25 foot long pondless waterfall with a 4 foot grade drop. It calls for a 5' x 4' x 2' basin to catch, store and recirculate the water back to the weir at the top. It also calls for cutting "steps" in the hillside for each waterfall along the stream. What the plans don't account for is that all this digging has to take place in the most compacted, hard and rubbery clay soil imaginable.
So far, I had used a Mantis tiller, a pick ax, a tool that is heavy and is designed to cut edges or shape sides of deep holes that I can't recall the name of along with shovels and a 5 gallon bucket and a garden cart. At last count, I had removed 11 inches of depth and I was exhausted.
I started thinking about renting a jack hammer. Around here, those go for $70.00 per day. In addition to the water feature project, I also have several retaining walls and a flagstone patio along with electrical and water lines to dig and bury so $75 times 4-5 days started getting me to thinking about buying something.
I looked at everything, but I saw nothing. That is to say that nobody carries demolition hammers in stock. Maybe it's the economy and stores have to watch what they carry, especially when it comes to construction/demolition tools when nobody is building. In any case, this purchase boiled down to academic research.
After altogether too much time spent comparing apples to oranges and granny smiths to golden delicious, I decided to focus on the tasks at hand and it appeared that something in the range of 9-10 ft lbs of energy and 10-15 lbs of weight would strike a balance for what would suit my needs. That seemed to mean something in the $500 or so range.
In the course of full disclosure, I had a 5 year consulting contract with Hitachi (hard drive folks). My impression of the company as responsible and good corporate neighbors is pretty high. They are environmentally responsible and operated with high integrity in my dealings with the company. In addition, I bought a Hitachi chop saw some years back and still find it a great tool to use. Now that I think about it, I also have a Hitachi 1/2" corded drill that was built like a tank.
Still, I had a singular doubt about the Hitachi demo hammer and that was ironically about one of the features that attracted me to the H45MRY.
One of the selling points for this product is that they have developed a shock isolation system that they tout as being easy on the mechanism as well as easy on the user. All sounded pretty good. But, I have always believed that it was hard to "negate" energy in a tool without taking away from the overall performance of the tool. Whether it was in the form of using energy to counter shock or fitting an isolation system that removed the user from shock as well as direct contact necessary to use the tool with precision, I have always had my doubts about the overall usefulness of "comfort" features on serious tools.
That all changed with the Hitachi demo hammer. With the clay spade I ordered along with the tool, I went out today and doubled my previous efforts clay removal from my streams water chamber in less that 30 minutes (as opposed to several hours and way too many tools.
This tool is powerful enough for any landscaping digging I will have to do in my all but undiggable clay property. In addition, I feel no residual effect from using the tool. I have used other demo hammers with little or no shock systems and felt tingly for some time later. Not at all with this tool.
While I am sure that the Makitas, Boschs Dewalts and other makes of the same performance class are competent performers, I can say that choosing this model has left me highly satisfied. I will get a ton of use out of this tool and I like that fact that I can put it down and feel no after effects.
Very highly recommended.
