Most of that hour and 1/2 was spent using the pry bar to bust through the limestone.With the Makita HM1500B we were able to cut the time to about 1/2 hour per hole. Hey, I'm not the young buck I used to be at just over 50, and am a software engineer by trade.Today we dug 8 holes, and plan on digging another 18 tomorrow.
The advantage of buying the Makita is I now have a great jack hammer for future projects. Using the Makita, has kept me from having to contract out the hole digging (at a cost which was slightly less than the price of the HM1500B).
The Makita HM1500B has made quick work of digging fence post holes. Previous to using the Makita, digging 5 holes in a day would pretty much wipe me out, sometimes even taking an additional day to recover.
flk We were averaging about 1 1/2 hours to dig each hole, using a tractor mounted auger, a set of post hole diggers and a 6' steel pry bar to bust through the limestone rock common to central Texas cliche.
But far more important, I am not absolutely worn out.
Usually for installing egress windows in basement walls or for moving underground plumbing. This tool broke through the rest of the way in minutes.
I was able to break the piece into 12 smaller pieces within about 5 minutes to make it easier to carry. We were left with a large heavy slab 10 inches thick that had been in the hole.
I am a builder and remodeler. The wall was 10 inches thick and the the blade can only go down to about 4 3/4 inches.
Great tool so far My company frequently has to do concrete removal work.
The first time we used this tool was to go through a basement wall we had scored with a concrete wet saw.
I started off with a pick & sledge and rate this tool as 200 times easier. The HM1500B accepts standard bits which can be bought at Home Depot. I have about 5 cubic meters of various stages of decomposing granite to remove. Or, for every hour breaking with this hammer, you would need 200 with the pick. It is a little heavy with the bit in place, but it does the job. The spade bit slices through the soft granite like butter. And the point bit eventually breaks hard rock into managable pieces.
It has worked well for everything that I have used it for. I like the light weight of this tool for a jack hammer. I have used it for digging ditches with a 5 1/2 inch clay spade, and breaking up small amounts of concrete.
