Most Helpful Customer Reviews

as an electrician I use this for drilling holes through metal studs when installing conduit. The thin walled design means you are removing less material so cutting is much faster than with traditional hole saws. The spring works perfectly flinging the metal discs out of the tool and freeing it up for the next hole. They are also much shorter than traditional hole saws allowing your drill to get into tighter spaces. Bought 2, 2 months ago and have since drilled many many holes with them without any problems or signs that they are slowing down. My foreman saw it in my drill and had never seen one before. I suspect he'll be getting a few soon. Just a huge time saver and worthwhile small investment.
The best hole saw on the market! I'm reluctant to review these hole saws, there so good I don't want anyone else to have them. They will pop a hole in a panel in seconds, clean & burr free. I have been using them for about 3 months now and just started a new Job. Using a corded hole shooter is the best option for this hole saw with a 5/32 pilot hole. Drilling multiple 3/4"(for stud punch) 7/8"(1/2" pipe) 1-1/8"(3/4" pipe) 1-3/8" (1" pipe) using Lenox tool lube (this product will save your tools) I've gotten 600+ 3/4" holes out of one hole saw (The one I'm rating), and I figure to finish the job with the same hole saw. That will easily be 1000 to 1500 holes with one hole saw that works!
Major time and $$$$$ savings!!!!!!!!!
I build control panels mounting 22mm industrial pushbuttons in the doors of sheet metal enclosures. A 7/8" knockout punch or hole saw fits the button. Chucked in a Dewalt impact driver, you can feel the saw progressing through the metal. As an example: I still drill an 1/8" pilot hole at center punch marks to ensure alignment with other holes but the saw took 12sec to go through a 14 gauge steel panel door. I didn't have to dig the slug out of the saw. It just falls out. I used to have to rat tail file the burr off the hole but this saw is clean enough to skip that step. I've cut 60 holes so it is relatively new. There may be more of a burr as it gets older but it costs only 20% of my carbide tipped hole saw so I can replace it more often. I would suggest not using it on plastic. It's tooth design apparently makes so many fine threads of plastic inside the hole saw, it clogs up the ejection spring and jams the cut out slug of plastic inside the saw cup. Use it on... Read more
