ASNOMY Tungsten Carbide Tipped Hole Saw Drill Bit for Hard Metal, 4 Inch T.C.T Hole Saw Cutter with 2pcs Titanium-Plated Pilot Drill bit for Metal, Stainless Steel, Iron, Wood, Plastic

I needed to drill through some thick steel. I didn't need that drill bit to drift also. This drill bit was perfect for what I needed. Extra tip, you should really use a smaller drill bit to place a dimple in the metal. Just a small dimple to make sure. After that it just grinded up the metal and made a precise hole. It's really a metal hole saw drill bit. Badass!

Just the size for the project that I needed it for. It cut through fiberglass. Excellent condition. Packed well.

Exceeded my expectations. Had to increase a hole on a trailer hitch which in it's self is a pain, the hole saw made quick work of it. The cut was accurate and clean.

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.

Love this hole saw. Used primarily for aluminum sheet metal. had a low deviance on clearance. pilot was good as well. saves me a frustration. good value for the price.

My husband really likes this drill

Exactly what I was looking for to put a peep hole through a metal door.

This worked as described. Always a clean cut, even through steel.
