#1 Drill Speed Concrete CORING BLUEROCK

We've been using hand-held rigs.Drill 1. 5 "through 8" pipes through concrete slabs, walls and voids. It's not really supposed to use more than 4 ", I believe this unit. But they work. Has passed several handheld devices: Diamond Products Core Burn,CS Unitec (Eibenstock), Kor-it,Core Burn WEKA and so on.

Probably tried everything. We may have two years before the big brands become rubbish. There is an abandoned diamond core hole in my office, which is now about a year old. Although we do use larger bits and understand the wear resistance of the machine, we get almost the same service life from BlueRock.

This one is almost as long as the price of 1. I paid about $1200. 00 (Eibenstock)-$1600. 00 (diamond / core hole) for big brand handles. So far, this is the best performance-to-price ratio. Even if you rent from a joint rental / HERC/SunBelt, etc.

, you will pay a few hundred pounds a week. Picking up water is a joke, but it's easy. If big brands can give us a better life expectancy, they are likely to stick to it. But they didn't. At least not for us.

#2 BLACK DECKER BDCK502C1 GoPak 4 Tool

This set of equipment is very suitable for the family DIY project. Maybe doing a little work at home. Please realize that the drill "knows" that if you want to peel the screw, stop. I wish the drill had more power, but I've already said it's true of every drill I buy.

The sanding machine works well. I suggest you buy yourself a 3-inch and 1-inch triangular sandpaper. It only has two pieces of sandpaper. The saw is great so far. I have no problem with it. Two separate saw blades followed it.

The lamp is self-evident and works well even in a dark room. The only problem is, I hope it comes with two batteries, or the extra battery is not $40! I suggest buying an extra battery for this set of equipment.

There's only one of them. Well, that's if you're going to use this setting a lot.

#3 Happybuy Drilling Handheld Variable Concrete

I was going to rent a core bit, but then I decided to try this one because it was cheaper to buy it than to rent one. It is packed in its own box, with extra brushes and all the components it needs to run.

I connected a drill bit with a diameter of 18 "long 4" to the drill bit and began to drill. I drilled in from the outside, and at first I was nervous, worried that the bit would grab the bit at some point and pull it out of my hand, but when it was finally caught, I realized that the bit was very well designed, and when the bit caught it, it stopped smoothly and didn't pull it out of my hand.

I spent about two hours resting, drilling through 10 inches of cement and rebar, and the drill never got hot and never skipped a beat. I spent about two hours resting, drilling through 10 inches of cement and rebar, and the drill never got hot and never skipped a beat.

The price left a deep impression on me. I think it will be a tool, I will have it for a long time, and I believe it will work when I need it. I will not hesitate to buy from this company again.

I cut a few 6-inch holes in 12-inch solid concrete with steel cables, each for 10 to 30 minutes. Normally, it takes me about four hours to manually complete the SDS bit. SDS costs about ten times as much as this monster, but I guess time is money.

Pros: simple, undecorated, rugged, well-crafted, fast customer service, durable, glossy (for couples), rugged, very fast, accept conventional garden hoses, current regulation Cons: occasionally it still pops up a 20 ampere circuit breaker, I connect it specifically, it's worse than a foreign language pamphlet, what you get is expensive, including whether you need their wrench or not.

The motor dropped a lot of black dust, which meant that the brushes needed to be replaced, the bits included a lot of accessories, and there was no explanation of what they were, and I needed to contact Bluerock to find out (only to be told that I needed to know more about the machine sold to the public on Amazon, after polite and timely explanation).

There was no simple way to rotate or tilt the drill bit to remove the core from the drill bit while drilling. The pipe clamp is leaking and loose, and the pipe touches the drill bit without intervention. I'll buy it.

#6 Einhell TE CD 18 Power X Change Cordless

I like the locking position on the drill bit forward / reverse switch > the working light is folded and the battery provides a solid base so that you can point the light to where you want / need. The handle on the drill bit is made of rubber, so you can get a good grip (with smooth.

#7 Happybuy Diamond Drilling Capacity Concrete

I need to drill some holes in the concrete retaining wall and consider renting a hand drill. I know there are so many holes I need to drill, it won't be a day's work. I calculated and decided to buy the tool instead of renting it.

It arrived within two days (thank you, Prime Minister) and pulled it out of the box. The packaging of such a heavy tool is poor, at best, that is to say, the power supply is actually damaged. I needed to use this tool the next day, so I temporarily repaired the power cord and used it.

It does a great job, and the rig installed is a huge backup protection program. Instead of dragging the bit and bit for more than 30 minutes (each hole), I can get comfortable sitting while the bit does the work. If you have the patience to drill into concrete, it has the ability to drill a 4.

25-inch hole-it's not a fast process. I still have a few holes to drill, but so far, I am very satisfied with the tool and the overall purchase.

#10 Lithium Ion Cordless Adjustable Function AQ75024G

When I received this hammer drive / bit, I thought how powerful this small lightweight tool could be because it was so compact and cute? I was wrong! Dude, can this thing drill through? Yes, it can! Installing a swing doorman used to be a hassle.

It took me more than 15 minutes to finish. I just tried to install one last night, and it took me only five minutes to finish it easily. Take a look at my video to learn about the last point of the installation.

Save more time to deal with secondary and major home decoration tasks. I can't wait to wait until the weekend to solve all the things I've been waiting for a while. I love this thing. Everyone has to have one of these!

I'm not kidding.
