Customer Reviews

RotoZip Carbide bit RZ250 1/4 inch.
This little piece of metal performs magical cuts in most of the hard surfaces I have used it on. And it lasts & lasts. A time-saver for me at work.

Great for plaster/buttonboard remodeling
I am a remodeler and cutting plaster/buttonboard in older houses can be tough. I got only one hole cut for a six 6" can lights before my Greenlee hole saw was ruined. This bit in my Rotozip cut the last five and plenty of holes in the walls for outlets and for pulling wire (unlike a regular electrician I have to patch my holes so a square cut is worth it) . It did take a couple bits (you can see the "teeth" getting worn down) and near the end of a bit's life, you get more cutting by working the bit in and out. It's a dusty job and you should wear more than a cheap dust mask. I also found a full face shield worked much better than goggles.
I have been trying to buy some more of these bits at Home Depot (couldn't wait for a Amazon order) but the clerk told me that Bosch had just bought out Rotozip and that it would be a while before new bits came in under the Bosch name(?)
$10/bit is expensive but they get the job done.

a great buy
This bit is incredible. It has cut through everything that I have used it on and it is still as sharp as the day I got it. It really lasts a long time. Great for any person who had stuff to cut and wants a bit that will cut through many different surfaces.
