ASNOMY Tungsten Carbide Tipped Hole Saw Drill Bit for Hard Metal, 3 Inch T.C.T Hole Saw Cutter with 2pcs Titanium-Plated Pilot Drill bit for Metal, Steel, Iron, Wood, Plastic

What a cutting animal!!! Work GREAT, Be careful, it bites hard and pulls on the drill. AAAAAAA++++++

I used it to drill a hole through plate steel, worked great!

These hole saws are really the cat's meow. I have used the cheap hole saws for years and decided to spend a buck and give these a try. WHAT A DIFFERENCE!! No wobble at all and as long as you take your time, they will eat right through the steel that you are boring through (I was cutting through 1/8" mild steel). I now have several sizes and I will not use the cheap-o hole saws anymore. The hole that results is VERY accurate with no sharp edges. I am sure that these hole saws are very durable and will last me more than several years. They come with an extra center drill and spring which is a plus. I am extremely pleased with the speed with which they cut and ease of use.

Loud cutting. Very aggressive toothed hole saw. I maybe expected more because I already owned sizes up to 2 1/2”…. Those cut even better. Same brand. Larger the diameter, slower cut - should have anticipated

Great tool, cut an air gap whole in my stainless steel sink in under 12 seconds! Would buy again and cheaper that anything that Home Depot sells. 5 stars!

I used the 3-1/2” to bore the center of a 6 hole 16” Chevrolet wheel, one bit did three wheels and I purchased another one for the fourth wheel, worked much better than I expected and the finished product looks like factory.

I need to make a hole in an old fridge metal wall for a fan. Ones I tried before just went round and round barel scratching the surface. This one went right on through, no problem.

Feels pretty solid. The plastic cylinder packaging seems a little on the small side. One tooth was broken off and was rattling around the bottom of the cylinder.
