Does the job a lot better than some bits I've used. It has pulled through after from some thick metals and still no sign of wear

After a failed attempt using a cheaper step bit, this bit saved me. I needed to drill through a double-wall insulated smoker to install a cold smoker attachment. 5 minutes after receiving the bit I was through both walls and fully installed 10 minutes later.

I always read reviews when I buy on Amazon. You know how it is, sometimes you still get a LEMON. This ain't that. I read negative feedback, and in most cases I THOUGHT gee I bet they had that thing on a single speed tool, hopefully not a light handtool, and with ZERO speed control.Ok so this ITEM. Works like it's supposed to work, IF you use a slow speed, and have a tool that can handle this thing. A decent drill press it's absolutely agreeable with that. A heavy duty hand held drill with a GOOD clutch, settings for slower speeds, and a good locking bit vise, will also get it done. A puny little hand drill, and you may have issues. Don't blame the bit for that, LEARN how to use tools, and use equipment suited for the work.My bit ate a hole through 1/4" plate steel like BUTTA. Of course I was using a decent drill press, and had that metal clamped down hard to the table. Went through several pieces of thinner plate, and some mixed metals my WOOD boring bits wouldn't touch. I didn't let them anyhow. On some of the thinner stock I used a 18 volt cordless Milwaukee, and zoomed through everything I encountered, right up to and slightly past the 7/8" diameter.Fun bit, easy to use if you use it right.

I bought this for my brother in law who loves creating artwork using sheets of metal. His "art studio" is a small section of the garage so he doesn't have a lot of space for tools. This is perfect for someone like him. You can create a variety of sizes depending upon how deep you drill it. It's a very sturdy piece. It drills through the metal easily and leaves a clean hole.

Needed to drill 60 holes in heavy gauge sheet metal fire ring liner (from Tractor Supply).Tried my bi-metallic hole saw... literally ate the teeth off without getting halfway thru one hole.Ordered this - it was a bit more, but hardness rating is worth it.Drilled ALL 60 HOLES, to maximum 7/8" dia., without even needing re-sharpening. I used a heavy duty handheld power drill. This bit is WELL WORTH THE PRICE. Recommended.One thing: with a hand drill, you need a *solid* grip to keep bit perpendicular to the surface. If the drill jumps or cocks it will bite the metal wrong, stick, and gouge the sheet metal. Even then, the bit is hardened and does even get a nick in the cutting surface. Go SLOW - feel each depth cut through.
