This works well to drill into Granite. I am using a 1.5 x18 inch rock drill bit every 12-18 inches in some granite rocks to split them with Dexpan. It does take around 10 minutes to drill down to max depth, but this drill works well.I did have a problem with the first drill, but the company shipped out a replacement quickly without any issues. I think the problem was with back-to-back usage, I didn't let the drill cool between holes and I think I overheated the chuck, the bit fell out when I picked the drill out of the hold, and I think the chuck jammed when cooled. I could no longer lock a bit into the chuck.Give it a 20-minute rest every 20 minutes, and I don't think you will have my problem, Both the original motor and the new one run great. I drilled a total of 6 18 inch deep holes before the first failure (4 in a row before failure)

Drilled 10 1 1/2 holes for tee posts in various hardness rocks Still performing well.In very hard rock, 5 min continuous use engine starts heating up.30 rock holesStarted making a noiseNow bit does not stop turning when idled down like it did before

Funciono una sola vez y no vuelto a encender, lo envie al taller y me informaron que no valia la pena repararlo

Garbage with no parts acailable to replace anything that breaks. Company was good for returning money. The only way it will last any longer than a month is if you don't unbox it and look at it wrong

The media could not be loaded. I haven't used this tool to actually put in work at the mining operation yet, that comes tomorrow. However I took it into the backyard to see how it runs. Upon checking that nothing was loose, and that the machine was properly greased, I added half tank of fuel and primed the bubble maybe 5 - 7 times to get gas flowing. without even turning on the choke, it started first pull. I let it warm up, smiling at the sound of the 2 stroke engine running beautifully. It shows 2 bits in the picture, but it came with 5. I drilled a hole in a rock in the backyard within about 10 seconds, turned it off, and started it back up later again, with only one pull.UPDATE: just got back from the mine, and this thing held it's weight and came in GREAT use. Again, started first pull absolutely every time throughout the day. Doesnt burn fuel all too fast, we used it quite a bit today, maybe 3 hours total running time and I never had to add more fuel from the first morning fill up. What a fun tool, thing drills pilot holes like a beast too but probably best to use water or something while drilling because it burned the tip after only a couple holes or so. So far, really happy.
