Good bit, fast drilling

Very well made as are all of Milwaukee’s tools. SDS tools are easy mounting and easy to remove, no keys necessary. These bits cut like a dream. Shank is precision ground to fit SDS MAX tools. Very fast and smooth cutting. The way the carbide is shaped and sharpened it should hold up for a lot of holes.Photos would show little so I have none with this review.

I needed to drill a bunch of 2″ deep, 3/4″ holes in a well cured concrete slab. This bit did a great job, drilling the holes in no time. I found that I got the best results if I supported some of the weight of the drill. The entire weight of the drill was too much pressure on the bit for optimum drilling speed.After a dozen holes, you could hardly tell the bit had been used. This is a well made bit, and I expect to drill a lot of holes with it. It should easily last me for the rest of my life…

Milwaukee makes great products!. Only tools I buy.

This bit drilled quickly and effortlessly. I recommend the Concrete With Rebar bit weather you expect to encounter rebar on the job that the bit is being purchased for or not. Expect the unexpected, such as hard gravel or other embedded metal or hard debris. This is the line of bits for the job.

Expectacular

Well made (in Germany) and has the 4-blade cutter. Works as well as a Bosch or Hilti at less than half the price.
