Erbauer Bi-Metal Holesaw 20mm is rated 2.8 out of 5 by 6.
Rated 1 out of 5 by from VERY POOR QUALITY - DO NOT BUY I purchased two of these, thinking it would be sensible to have a back up. I used it to drill 3mm mild steel, using a pillar drill and plenty of cutting lube. After two holes the teeth had completely melted away to nothing, leaving a smooth surface! The second didn't even manage one hole before all the teeth were completely gone! It literally doesn't do the job it's supposed to do. Buy cheap, pay twice. Lesson learned.

Rated 4 out of 5 by from Does the job. Reasonable quality and inexpensive holesaw that is perfectly adequate for the job I need it for (cutting holes in plastic enclosures for 20mm plastic conduit).

Rated 2 out of 5 by from Have for a backup only It cut through the metal trunking well for the first few holes that's about it, after that it was a battery sapping burning tool. Bailed me out when I needed it but for the price and performance this is very much a backup holesaw.

Rated 2 out of 5 by from dont expect to much It might be round and have teeth but don't expect much of a bite .Save up and buy a more expensive brand or 3 of these. Doesn't last 5 mins cutting through metal enclosures.Teeth broke off after a few holes
