## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect for my use
*by J***O on March 15, 2020*

Drilled a 4 inch hole 10 inches deep using this extension, (started with the 6 inch 5/8-11 then bought the 12 inch long extension) on a Milwaukee and a Dewalt Angle Grinder, extremely well made for the price, held up to the abuse that I put it through, nicely

### ⭐⭐⭐⭐⭐ Flawless
*by I***O on January 8, 2023*

Did exactly what was intended to do. It help me bore 3 separate 2.5" holes through a 24" fieldstone foundation. Took the abuse of alot of resistance, never saw hammer mode, and is exactly the way it was sent to me if I ever need to use it again

### ⭐⭐⭐⭐⭐ Yep - works
*by D***P on July 11, 2016*

This is the text from my review of the Concord Blades CBD04500HP 4-1/2 Inch core drill bit that goes with this extension...=========================================================================It really does just what its supposed to do...I bought this to put a 4" air exhaust duct in, through my foundation - brick face over cement block, about 14" thick. I first used just the drill with the Concord Blades HEX500 Core Bit Adapter.When it was getting too far into the wall I added the Concord Blades EXT06D 6 Inch Core Bit Extension.Drilling freehand was a bit of a trick to get started and it was really tiring, even with my heavy duty drill. I will say that because I went freehand, there was a bit of drift (no surprise) and I did not go 100% straight but the fact that I had a 41/2" hole for a 4" pipe allowed everything to fit easily.I should add that I had my partner on hand with a garden hose to wet the drill while drilling. I don't know how much it helped, especially after it was well into the hole but it did not really get hot which can only be a good thing...All in all, less expensive than renting and I ended up also using it to drill a hole through floor tile for a toilet drain line that I was installing in a bathroom floor. For that I used a simple piece of PVC pipe to help position the drill and reduce drift. It worked great and was far neater than I would have achieved with the grinder and nippers.
