## Questions & Answers

**Q: Does this blade fit a regular dremel multipro? model 395**
A: Thank you for your question.  The US520 Dremel "Ultra-Saw" blade is intended ONLY for the US40 Ultra Saw TOOL.  This is a different "type" of tool than your small, "High Speed Rotary Tool".  The blade on this US40 is way too large to fit on your 395 tool.  So, the answer is, "No, they are not compatible with one another".  Should you have future questions, reach us on our toll free number of 1-800-437-3635, Mon-Fri, 8 am - 5 pm, CST

**Q: Can this be used in the flush cut position?**
A: Thank you for your question.  No, it cannot be used for flush cutting.  All of the flush cut wheels are recessed in the centers.  If you have any questions, you can reach us at1-800-437-3635
m-f  8am - 5pm C

**Q: Can this be used to cut Hardie board?**
A: States it will cut masonry board (hardie).  Never tried it.  Would think for a thinner piece and not a lot of cutting.

**Q: Will this blade cutr ceramic tile?**
A: Thank you for your question.  You have asked if the US520 Ultra Saw "Masonry" Cutting wheel will work on cutting ceramic tile.  The answer is "No".  This wheel is for "masonry materials" such as stone, slate, cement board, bricks, concrete, cement backer board.  For ceramic tile you would want to use the US540 "Diamond Tile" Cutting Wheel.  This wheel will cut most tiles and masonry materials such as wall tile, floor tile, porcelain, slate, stone and cement backer board.  Should you have future questions, please feel free to contact us at 1-800-437-3635 Mon-Fri, 8 am - 5 pm, CST
