I had a pair of Olympic adjustable dumbbells that I never used and wanted to use the sleeves to convert a 1" Titan cable machine to Olympic plates. They had a half inch bolt hole that needed to be embiggened.It took a while to find a 1" bore step bit to do the job, but this not only did the trick it was faster and easier then planned. I likely dulled it out a bit, but buying high quality chromed Olympic sleeves would have cost 3x or more the $$ and being able to reuse what I already had was great.

Drill tip snapped after drilling second hole. Used Tap lubricant and slow speeds, and it took almost 10 minutes to get only halfway through 1/2” corten steel. Let drill and bit cool down, started second hole. After 4 minutes of drilling the tip snapped. Similar step-bit product from Teco cut through same steel plate like butter, less than a minute.

Here on the homestead, we've always had a lot of faith in Bosch products. This drill bit was a reminder of why we have always supported this brand. Goes through sheet metal well. It's designed so well, you get nice clean holes each and every time. What's really impressive is that you get way more battery life from your cordless drill than you'd normally expect using a drill bit like this. A better quality bit means less juice is needed over time. So you can accomplish more on the same charge than with those bits made from competitors.Are there cheaper drill bits out there? Absolutely. But you get what you pay for. I'd rather pay a bit more, and have a bit that I know will work quickly, drill effortlessly, and provide nice clean holes. You don't spend $10 on a lousy socket wrench set from a big-box retail store, would you? So don't go cheap when you know quality is what you deserve, and will save you time in the long run. This bit gets a big thumbs up from me, go ahead and add it to your cart. See for yourself if it does for you what it did for us.

It’s been milled out of a block of hardened material. It’s dense and has a hefty feel. It will do the job it’s made for. You can drill a small hole or keep going and just keep making a bigger and bigger hole. Something of a way not to over bore a hole is to put black tape at the line of the size of hole you are going to bore. Then you know where to stop. A solid tool for every mechanics tool box. It’s a bit pricey but it does what many bits would do, also less time changing out bits converts to less time on any particular job. Four Stars ⭐️⭐️⭐️⭐️!!!

TLDR: Excellent for sheet metal and if you need to drill a bunch of different sized holes. It is pricey though, so if you just need a few holes in wood, get spade bits.We just redid our living room, and in the process rerouted a huge number of cables for audio visual components so I got some use out of this.Before I would try to drill a hole for cables with a wide drill bit and then sort of move it around the edges to try to make it bigger or I would use a spade (paddle) drill bit.but these can be hard to force through thick wood and you have to be careful to hold them absolutely perpendicular. This resulted in a non circular opening and often with rough edges.This drill bit makes it easy to make a hole up to an inch wide. I know it says 7/8th but the bit actually goes up to 1 ⅛ width (but then it is hard to make the hole even). An inch wide is NOT wide enough for a fat plug at the end of a cord (the ones with 3 prongs) but I can fit the 2 prong versions through with a little wiggling and if I force the drill all the way through.Using a 20V Bosch cordless drill, I used it to drill holes in the following: ½ inch particle board. ½ inch red oak, some thin plastic and very thin sheet metal (not sure how thick this was, it is a cheap filing cabinet). This was absolutely amazing on the sheet metal, one can control easily how big the hole is and drill holes of various sizes without switching bits. The tip does not “walk” when you try to start it, so you don't need to center punch like my Dad taught me. It works fine on the wood too.The “step” part means that if the material is bigger than ⅛ the hole itself will be “stepped”. You can sort of control how the hole looks by going a bit deeper than needed so you get a hole with a “slope” towards the middle. This was nice in the wood as the cables are then not up against a sharp edge. You can feel the “steps” as you drillOnly the ⅞ and 1 ⅛ are marked on the steps. So you need to count or measure if you need a precise hole other than those sizes.
