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

This is great core drill I use it to core the 8” hole for my kitchen exhaust fan the wall is 12” thick . It is even cut through the metal inside the wall the United rental rent for $280 for the drill and 8” bit , I rather buy this and save for future use since my house is build by concrete slab I highly recommend I am feet happy with this purchase

i core drill everyday installing fences and gates, the last drill lasted me 2 years, so for this price its a bargain! no need to spend 1000's on hilti etc, you wont be disappointed!

This is perfect for drill in the ground for my tulip bulbs. It’s a little had to mount to loose soil so sometimes I just holed it in the air.

This is a powerful tool. With the correct diamond core bit, it will do the job. I broke my shoulder rest and will need another one.

For the price it is very good, ..................did the job that it was expected to do.

I bought this to make holes in a new lava-rock/concrete wall so I can mount an aluminum fence with 2" posts. I didn't get to use it until today and I am really impressed with how well it worked. I only drilled 3 holes because I was learning how to use it but it really was easy. A couple things about how I'm using it.First, I'm not bolting it down like you're supposed to. Instead, I have a 3 foot long 3x4 with a bolt through one end to locate the 2x4 in the drill stand. It's not bolted to the drill, the bolt in the 2x4 just sits in the slot on the drill so the 2x4 won't come out while I'm using it. The other end of the 2x4 has a small piece of 2x4 attached so that the longer 2x4 is essentially level when it's on the drill base. When using the drill I just sit on the 2x4 in order to secure the drill.The second thing is I adjusted the gibs on the drill head so the head can slide very easily and I just use gravity to feel the core bit. The whole setup takes less than 5 minutes to drill and 8 inch deep 4 inch diameter hole.I've got a few hundred holes to drill, hopefully it will last. :)

used it it drill 2 8" holes through 7" re-enforced concrete walls. Heavy to place but powered right through. Can't tell you about longevity as I only have 2 holes right now - but this with an 8" bit was far cheaper then pro-drillers and the result is perfect - took about 30 minutes per hole - going slowly. You have to monkey around with the water feed though - not difficult and not that messy if you are careful

Excellent product, terrific price. Would recommend 100xs over. Just what we needed for core drilling.
