RotoZip XB-TC1 Tilecut X Bit

Used with RZ2000.The GOOD:This thing blew right through (cleanly) hardy-backer. Found that out after failed attempts using wood/drywall bits. Also goes though thinner wall tile cleanly and pretty quickly.The BAD:Try this on 3/8" porcelain floor tile and you will ruin your bit almost immediately. If you need to make a really really (REALLY) small hole, this could do it, but plan to expend the entire life of a fresh bit on that hole. Or better yet, find a better bit or another option to get it done.SUMMARY: Great for light duty tile/backer cutting, worth keeping available if you are in a jam with something heavier.

the drill bit worked well for the first 2 or 3 cuts. then it dulled and would not cut easily. i am glad i got 5 bits. thank godness they were cheaply priced.

I boght two of the 1/4 bits for fiber cement and snaped both of them within 15 min of use.The 5/16 bit is much stronger and holds up well.

This thing broke within minutes of use. Beats me what the heck happened but I suspect inferior quality somewhere down the line.

used once to cut tile to install shower faucet. needed to cut a circle

I ordered this to enlarge the hole in my HardiPlank cement siding to feed my security camera cables through. It did the trick quickly. I attached it to my router and away I went. Great bit!!

Good quality.

Couldn't even get one tile cut with it
