Customer Reviews for Milwaukee 1-3/4 in. x 23 in. 4-Cutter SDS-MAX Carbide Drill Bit

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.

The tool is doing a great job and works as intended.

Cut smooth through 8 in concrete wall. Minimal pressure on the bit just let it work it’s way through on its own.

Cut thought rebars like butter.

I am a contractor of 25 years who drills over 10000 holes a year These bits are better than a hilti bit as the hilti bits break in half or just snap off the tips. I tested 4 different brands the milwaukee hammer drill bit has lasted the longest and never broke and will cut thru rebar fast. I typically buy about 50 to 100 bits a year now only milwaukee bits Half the price of a hilti bit . With bettter longevity

Anything SDS-Max is worth every penny. Went through 6 inches of concrete in probably 10 seconds. Used a pilot hole for guidance but the SDS-Max is so powerful I doubt it even needed it. New OSHA requirements make these drill bits irrelevant in the contracting world today, but they're great for home use.

Lacking customer service at the tool area. Hard to get help to open locked case when needing tools. Inventory on roto hammer bits is always low, very rare you guys have what I need.

Milwaukee makes good rotary bits. They dont last very long if you use it to drill rebar though. I recommend using a rebar cutter and not this bit to drill rebar. It does drill concrete very fast.

Always have been pleased with Milwaukee's accessories good quality

With the proper hammer drill attached, this thing cuts through concrete, rebarb and rock better than anything I've ever used before.
