I recently purchased the Combination Set 1 3/4, 1/4, 1/8 Inch Diamond Grinder Bit Head Tools, and they arrived neatly packaged in a reusable case, which is great for keeping the bits organized and easy to access. The included sponges are a nice touch, though I haven’t quite figured out how to position them properly to keep the bits moist without tearing through the sponge. While the bits are high quality and effective, they feel a bit expensive for not being self-watering. That said, the different sizes are incredibly useful—the largest one tackles large areas quickly, while the smallest one excels in detail work. One downside is the design of the bit—since it keeps the glass about an inch above the work surface, achieving straight edges can be tricky. Overall, they’re good tools but could use a few tweaks for easier use.

I finally had a chance to try these on my inland. The larger one does not fit with the bitsert, but I can attach it higher than that. I also use a longer piece of sponge.My only wish is that they gave the grit number. I have no idea what grit they are, but these seem pretty fine when I tested them.I would get these again at this point. I'm very pleased.
