BLUEROCK Model 8Z1 Concrete Core Drill With Stand 110V 2400W Asphalt Masonry Diamond Drilling

A beautiful machine and works like a charm. Many happy clients with this core dirller.

This is hundreds of dollars less than other core drill sets. It seems a very good value for the money. Very sturdy components. Pretty easy to set up. Instructions are OK, there could be more information on use. There is better information on-line on how to use core drills. I bought this 8' version because I was going to drill 4" hole in granite rock for fence post, so I wanted more power than the 4" rated model. The wrenches that come with it don't work on all the parts an pieces that you need to adjust. A 22mm wrench or a larger crescent wrench is helpful. The off-on switch is a little strange, but it works. The biggest thing I would change on it would be to have a multi-speed option. That would make it easier to start in un-level rock and you could slow it down when you hear the motor start to work hard. I blew a 20 amp breaker when the bit got stuck on removal. I think using a 30 amp breaker would be better. It will shut down if it overheats but that means it's getting damaged. It still gets the job done and would do a 12" deep hole in under 10 minutes. Very glad I bought this.

I have used core drills many times and rented them or worked for companies that owned expensive ones. This one worked perfect and would recommend to anyone looking for a small investment into a great tool. We also purchased the 5 inch bit and extension. Everything worked great.

I drilled 5-5” holes 1-4” holes, and 13-3” holes through 7” of concrete. This drill paid for itself in one day on the job site. A great buy. Make sure you set the support lag well.

Picked up the drill last month. Shipped super fast very happy with that. Drill worked real good no problems with the drill at all. A little scarry lots of power. Cored a 4.5" hole through 12" slab. Had to start hole very slow a little bit of chatter at end of dimond bit. Could not tell if chatter was from bit deflection, bad anchor job, or drill press slop. Once a 1/4" gruve was made in slab smooth sailing. Wish it had rpm selection not looking forward to ever doing a larger hole, may be a little to fast. DANGER!!!!

I am a plumbing contractor. The stand is a bit smaller than my other machines but it is much easier to mount and transport. We core 8-12" concrete walls, 18-24" concrete encased sewer mains and 18-24" stone walls so far and no problems. I was a little skeptical but the machines performance has definitely won me over. I would buy again.

I rented other machines that were 8 times more the cost and they didn't drill as good as this unit did. Worked all day in the heat and never shut down or had any problems. I'm going to buy another one for the next job with the rolling base. Would recommend to anyone. hanks.

Really Like this machine. Works well and pounds through the concrete!!!
