Customer Reviews for Milwaukee 5/8 in. x 21 in. 4-Cutter SDS-MAX Carbide Drill Bit

It did not work as good as I thought it would. It was not an easy drilling process on my project.

We drilled sixty holes in a warehouse to anchor pallet racking and it could still do more.

Works as it should thank you

Here is the great and okay for this drill. With a hammer drill it went thru foundations in like 45 seconds. The bad is that it’s just a 1/4” short to go thru a 10” foundation when installed into the sds max hammer. They should have made it 1” longer to do the job on a standard foundation wall. That’s why the 4 star

The Milwaukee bits are no where as good as the Bosch bits! The Milwaukee bits are to prone to be grabby and constantly getting stuck in the stone.. I plan to return the two Milwaukee bits back to the store and hopefully have the applied back to my Home Depot credit card.

Ya, this works great

Had no choice but to buy a new rotohammer amd this brand was a pocket buster including the bits

It went through like a hot knife through butter.

This bit is a work horse. I used this bit with a Harbor Freight SDS Max drill, for 18” holes in solid granite. Each hole takes about 10 minutes and I’ve drilled 45 so far. The bit shows no sign of letting up. Although the bit is advertised at 23”, it’s actual drill depth is about 18”. Fortunately, this was sufficient for my job.

I drilled about a dozen holes and noticed that the drill was getting much harder to use. I looked at the tip and saw that the small chunks of the carbide broke off rendering my $109 drill bit almost useless. I was drilling clean stone with no rebar. I tried contacting Milwaukee and they never retuned my call, so I decided to take it back to Home Depot and they gave me a full refund. It was less than 30 days old.
