Rated 4.2 out of 5 by 22 reviewers.
Rated 1.0 out of 5.0 by Shouldn't have USA on it Just bought thing because harbor frieght's bits weren't lasting very long. By the second hole.. 3/8-1/2 the bit is shot. Won't even produce a chip. Honestly harbor frieght's lasted 6x as long. Very sad Milwaukee. August 4, 2016
Rated 5.0 out of 5.0 by Great step drill bit! Does exactly what I need it to do, and hasn't gotten dull yet after drilling several weatherproof boxes. August 16, 2016
Rated 5.0 out of 5.0 by very helpful drill bit We originally purchased this simply because we needed a 7/8" bit, but we have found many uses for this bit. It is very well made and able to widen holes in several types of metal. May 31, 2016
Rated 4.0 out of 5.0 by great tool Great tool,got me out of a big jam.i think this product is great June 21, 2016
Rated 5.0 out of 5.0 by Ingenious For the price and what this bit does, it is well worth it. I think you would be limited to how thick a metal you could drill through, except for the largest size, because of the way its tooth design is, but you can go though 1/8 plate by drilling half through one side and the other half from the other side, so all in all, it saves time and money..........SHALOM. Bro Randahl March 31, 2016
Rated 5.0 out of 5.0 by Best bit for drilling steel where you need a large hole. This bit turns your cordless drill into a workhorse. Very smooth cutting drill bit because of the design and how sharp it is. March 15, 2016
Rated 1.0 out of 5.0 by Good for one hole in mild steel Needed to enlarge some holes in mild steel plate from 1/2" to 5/8". Bit was dull and would not cut anything after one hole. Complete waste of money. February 17, 2016
Rated 5.0 out of 5.0 by Great tool to have on hand The bit was perfect for the job intended- drilling holes in ductwork for a humidifier install. The design allowed for different size holes and was well made. Made the job go easy. January 18, 2016
