Customer Reviews for Milwaukee 5/16 in. x 12 in. 4-Cutter SDS-PLUS Carbide Drill Bit

Bit drills in great and fast

First hole it worked well drilling into old concrete. Second hole and bit bent but able to bend back straight although it wallowed out hole making it unusable. The drill angle was straight and retracted cleanly from the hole and only light pressure put on while drilling. Third hole - same thing. I question the true quality of Milwaukee products especially since it is now owned by Chinese tool company Techtronic Industries. I bought a Diablo as replacement.

Worked great. Drilled through the concrete very quickly. Definitely recommend this bit.

It cut through concrete very easily and doesn’t show any wear yet. Solid bit.

Terrible Drill Bit and had to return for full refund. Didn’t make a dent in my concrete floor.

Drills though concrete like butter.

It drilled into the concrete effortlessly

Just what I needed. Wish price was cheaper but just happy they had it in stock. Bit cuts quickly and shows no wear after drilling upwards of twenty 5 inch holes

Works great in my M18 Milwaukee Hammer drill

The tips fell off all the bits. Returned them for a refund

Easy to use, worked like a charm?? Thumbs up all around for me??

Awesome tip on this bit! Works great with my cordless!

I needed some holes for tap con screws, and the drillbit that tap con sells, would barely penetrate the concrete wall that I had . It would hang up on rocks or I don’t even know what was in there, but it was sitting on one spot for a long time over and over again . Drilled each hole with almost no effort, and no stopping.
