Customer Reviews for Milwaukee 18 in. x 7/16 in. QUIK-LOK Universal Extension Bit

Great product great price

This is by far the best and most effective also efficient holesaw extension on the market. It is a little bit pricey but the Good old saying is you get what you pay for. The best thing is this extension will not loosen up why your drilling so know more loosing holesaw in the wall.

Needed to drill a hole through a floor joist spacer, unfortunately, the spacer was about five feet from the access point. So, I put three of these bad boys together with my 4” Milwaukee hole saw on the end. Worked like a champ! Though I had to assemble the 18” pieces inside the joist cavity one at a time. Also used it to drop a hole inside of a hole wall for some PEX.

Works extremely well!

I’ve put it through hell and it’s still holding up

Biult heavy-duty that workes great

The 18" extension works perfectly with minimal wobble using an 18" bit. I don't know if the black oxide is stronger than chrome but I'd rather have chrome hence the 4 stars. Black oxide will rust a lot faster than chrome. I clean and use wd40 silicone when not using. Highly recommend oiling the quick release between uses. A little oil will make the $28 extension last a long time.

Sturdy, used 9 sections to get where I needed to go! I will have this extension on my vehicle at all times.

It worked for what I needed the first time I used it. I put it in my tool box of drill accessories and the next time I needed it the set screw was missing. There has to be something better than a set screw that falls out while bouncing around in a tool box in my van. I never did find the set screw.

It’s sh—. Milwaukee bits and extensions don’t seem to ever be compatible. No help in the Home Depot either. Totally uninformed staff.

Item seemed to be of quality but it was not what I was needing. It was returned.
