Mollom Heavy Duty Carbide Hole Saw, Hole Cutter cuts Stainless Steel, mild Steel, Iron, Copper, Brass, Plastic (3 76mm)

Got the job done 8 holes in 3/8 steel plate

Used to install light on my trailer. Cut 12 holes and it the saw is still like new.

Very nice hole saw. Really tough. Ive cut thru plywood in a few seconds, but it does leave a ratty entrance and exit. Thats OK for roughing in plumbing or electrical work, NOT for veneer work!! This will not cut thru a 2x4 without stopping to remove the plug from the cutter a couple of times. Cuts Aluminum like butter. I use a cutting fluid made for just aluminum. I have cut 3 holes in 1/4 steel plate with no problems. Get your RPM way down for steel. Around 350 to 440rs. Again, I used a sulfur-based cutting oil for Ferris work. The hole saw is as sharp as day one.

Needed this to isolate broken screws attaching my deck stair treads so I could replace them. Using a 3/4 thick wood template to guide (could not use furnished centering drill as it would contact broken rusty screws) was able to remove old treads leaving the 5/8 core which I then split with a chisel and removed.

In a previous post, numbers were inverted. And I had given only a 3 star for this product. I am sorry for the misinformation. This product is fine and we are using it. It came in on time as stated in the order section. Again, I am sorry for the mix up.

Awsome holesaw need a very powerful drill and a strong grip and lots of oil

TCT holesaws can be damaged by impact. The box protects the carbide tips nicely. While I would have preferred a different size selection, this set is a good compromise for the money. The only thing I would like to be different is the shank. If the lower portion were a Weldon shank, it would fit in a magnetic drill chuck, enhancing usability.

Works great I love it

For the price I thought this was a throw away but it was quite nice. Have not subjected it to repeated use but surprisingly good.

Was checking on the comments and trying to buy one. Although not as good as Klein, looks all things go fine, better than the cost. Worth it.
