RotoZipGP16 1/8-Inch Drywall Guidepoint Cutting Bits (16-Pack), Cutting Drywall, For use with Roto Zip Spiral Saw

This bit works great as long as you don't let too much of the bit protrude past the sheetrock. That requires that the Roto-Zip have a functioning depth adjustment ... otherwise this bit turns into a planer peeling off the surface of the window and door frames. I had no trouble with the bits breaking as other reviewers had but I suspect that is because I took the advice of others and didn't apply a bunch of pressure ... let the bit do the cutting. They also don't last forever so when the tip starts getting burned down into the flutes it's time to chuck it and get another. I buy the Roto-Zip bits in the 16 pack so they are not terribly expensive. Work great on plastic electrical boxes ... again only if not too much of the bit protrudes ... if you can smell the plastic burning you're probably peeling the box while cutting the rock.

Good value for a set of 16 drywall bits. These 1/8" bits are prone to breaking off if too much force is given to the tool if you're not careful. So far the high speed steel of these has put up with some abuse and still plunge just as easy as the first time the bit was used. So far, so good.

So the bit itself works great, I thought it would fit a dremel trio and I wouldn’t need to get rotozip, but it does not. I did use in a regular dremel and just freehanded the depth to do 10 cut outs in a project. It worked but next time will probably get he proper tool. Or I probably will not, it worked once and I’m pretty cheep so what could go wrong....

Exact fit for my Dewalt. Good quality.

Great for cutting in boxes! Until, you push against a stud and snap it...after 3 or 4 you will get the feel and will love them!

I used these bits in a bathroom remodel were I removed the sheetrock and replaced it. This bit performed excellently throughout the whole project.

I finish hanging drywall on my basement and use only 2 from this pack. I'm new to drywalling but I didn't break even one of the bits. Recommended

Used one when boarding basement worked great
