Customer Reviews for 10'' Diamond Core Drill Concrete Drilling Machine with Stand & Drill Bits 4450W

Works just as good as the ones I've rented.

Great item. Great value for the moneyLou

Seems like a great product at a great price. Have not actually used it yet, but the visible quality looks solid and reliable.Item arrived damaged, but it was due to shipping damage. It's quite heavy and awkward and the delivery people or machines messed up the packaging. The main base, although solid metal, had a piece broken off. However, the shipper/manufacturer was very responsive and immediately sent me a replacement base without further action or cost on my part.Very satisfied with my purchase.

Very efectiveThanks

Muy bueno .. me sirvi mucho y buen precio ..

good product works better than expected and price was good

I needed to core drill some holes in a concrete retaining wall and looked at renting a "hand drill". I knew that with the number of holes I needed to drill that it wouldn't be a 1-day job. I did the math and decided I would buy this tool instead of renting. It arrived in 2-days (thank you Prime) and pulled it out of the box. The packing for such a heavy tool is poor, at best, and the power was actually damaged. I needed to use the tool the next day, so I made a temporary repair to the cord and used it. It works great and the mounting rig is a HUGE backsaver. Instead of lugging the drill head and bit for over 30 minutes (each hole) I was able to get comfortable and sit while the drill did the work. It has all the power needed to drill a 4.25" hole if you have the patience to drill into concrete - which is not a quick process. I still have a few more holes to drill, but so far I am extremely happy with this tool and the overall purchase.

Just got the 6 in version. The thread to the drill is 1-1/4 7tpi in spite of the 1/2 BSP in the spec, so that is the good news. The supplied drill is a couple of inches shorter than standard, so it would make it through a 12 in wall, but not a 14 in like the standard drills. The column is JUST long enough to accept a standard drill without having to block the base off the surface. The machine is NOT variable speed. It has an on/off switch only. Not the end of the world, but be aware. The label on the motor says 110V 50 Hz, so clearly a product made for the China Market and only slightly reprocessed (it has a US standard plug). It is a universal motor, so the 50/60 Hz thing should not be an issue, but 120V will probably be pushing it a bit. The flip side is that it should be happy on a fairly long extension cord and since it draws 20 Amps, that may be a good thing. Haven't had a chance to drill with it yet, but it looks workable and it is about half the weight of my 10in drill, so a lot easier to horse around for smaller holes. I got it for the 1" to 3" stuff because my big drill doesn't run fast enough to be efficient with small drills and I think it will be fine for that, but the whole setup is pretty light for anything bigger than about 4 inches. My big drill is a predecessor to the Bluerock line and it has been a beast, but it is heavy.

The drill was great until it quit working. I contacted the seller and after me sending proof of it not working they very quickly resolved the issue.

Good machine strong
