great tool bought for notching steel 14 gauge tubing for welding, amazed on how well they cut and last, I bought a few more of them as I had to cut some 1/4 steel so a pipe would fit through it,
I drill/sawed over 24, 1/4" steel plates with one saw and it was still going good, I did keep a light oil on it during the cutting process,
Firstly I am only a home handyman. A useful review for this item should be made by a trades-person who uses this size hole saw to death. Anyway for what it is worth, I initially purchased this size saw for a specific job and have used this hole saw on mild steel (18 gauge) about 6 times, on 1 1/2 inch hardwood probably the same number of times, and subsequently on softwoods and plaster walls/ceilings. All up probably about 25-30 holes. It makes the holes in all the materials neat enough for my purposes I am not doing precision woodwork here! The elongated holes on the side walls are great for removing cut material and the wall thickness enough to withstand any distortion that may otherwise occur because of levering the cut-out out with a thin screwdriver. The hole saw is still OK to use ,although I have not had the requirement for holes in metal recently. For my purposes it has already done a good job for the money. From now on in it is all plus!
I used this to cut a hole in a 1” thick piece of 6061-T6 aluminum. I didn’t have a machine slow enough with enough torque to use this as I would have liked. I settled on a Jet 16” drill press and it worked … but…At 200 rpm it was indeed too fast. Chip removal was a problem as they built up in the cut-slot and saw teeth and prevented further cutting so periodically I had to remove the cutter, clean out the slot before proceeding. Despite verifying the tram on the drill press prior to starting the hole saw cut at a slight angle. Don’t know why. After the job was done I mounted the arbor-hole-saw combination in a lathe and measure the run-out. It measured about 0.018” which I consider excellent and assembly eccentricity wouldn’t account for an angled cut. Overall an excellent tool, worked well, survived the job sharp and ready for continued use.
