I purchased both the Dremel 569 and 570 carbide grout removal bits to perform what I thought would be a fairly straightforward removal of old grout from our bathtub tiling. The bits work very well for about 15 minutes (i.e., about 7-8 linear feet of grout) and then go dull to the point that the bit refuses to cut anymore and the tip glows red hot even with slight pressure. I am now on my 14th bit and I still have about 15 feet of grout to remove. Given that these bits sell for between $11 and $15, this is a ridiculously short bit life for what is relatively soft gypsum material; it's not like I'm trying to cut through concrete or sheet metal. I've tried every possible technique, including cooling the bit down for a minute after each foot of grout removal, but nothing extended the life of the bit by much. Moreover, although I'm not a professional contractor, I have about three decades of experience with power tools, so I'm pretty confident I'm not using the bits in a manner that would be outside their performance scope. Dremel really needs to either drop the price of these bits to a couple of bucks and bundle them by the dozen, or upgrade the quality so that it actually is worth the current asking price. No one should have to pay close to $200 in grout removal bits for a simple, straightforward residential bathroom grouting job.

I managed to get about 6 inches of grout removed and then the cutter was so dull it stopped cutting grout. Very dissapointing. I ended up using a $2 hand grout removal tool tot cut through the grout on the 5 tiles I was removing.

I've used this several times to remove grout in a problem area around in our hall. It's worked great every time, chews up the grout in seconds.

Could have been made tougher. It does the job, until it breaks. And it will break sooner or later.

Great bit but you will probably need a couple of them-buy the bigger one if possible as they wear out quickly

Went through two of these bits. At first they do cut through the grout like a hot knife in butter, but after not even 5 minutes these things just stop cutting and simply stay in place and start to glow red hot if you try to move it. Way to costly to constantly be replacing these bits. Going to give the diamond wheel points a try instead (7134 and 7144) since they seem to be a bit stronger and cost less.

Every time I use my Dremel, I am more amazed. My husband and I redid are bathroom tile and this bit was very helpful....went through the grout like butter! :-)

I don't know what grade of carbide was used but it did not hold up. I bought a new one at Lowe's and it held up real well

I was a bit skeptical about the 570, however that skepticism is gone after watching this bit chew through grout like a hot knife through butter.

Great and durable bit for grout removal and other things where a 1/8th" slot or hole is desirable - anywhere carbide will do the job this is it.
