Review: Great Customer Support - Ok I read the instructions. Had water on the ready! Went slow! Did not force the bit! And oh it went through beautifully but the instant it went through It (the bit) broke!!!! It’s easy to use. Cuts great but it’s a waste of money to pay that much for one bit to break that easy!!! I just wanted to revise my review due to the kindness and support I received from The Robert Bosch Tool Corporation. I called and explained what happened and Andy M was very helpful and understanding concerning my problem. He promptly addressed the situation and mailed me out not only one replacement but 2. Now that’s what I call AWESOME Customer support. Something more companies should take advice from. Thank you Andy M !!! You’re the BEST!
Review: Love these for carving foam pumpkins - Unfortunately I dropped my dremel one night and snapped tip off , so I needed another. These aren't always in-stock in big box store. This is name brand and the quality you would expect when you use it properly just don't drop it like I did. LOL. You can see in second picture what I use these for. I went ahead and bought 2 so I wouldn't be without. I really do like that I have a thin more precision side and a thicker side that cuts through faster

### ⭐⭐⭐⭐⭐ Good diamond bit
*by G***G on December 23, 2024*

I do not recommend for drilling agate. Bit will dull quickly or break even under water. Never use dry for drilling stone. Works well for materials of 7 or less on mohs hardness scale.
