Review on Raizi Diamond Finger Milling Bits For Enlarging Shaping Holes On Porcelain Tile Marble Granite Milling Tools 2 Pcs (20Mm(13/16 Inch)) by Geoff Foster

I recently purchased the Raizi Diamond Finger Milling Bits for enlarging and shaping holes on porcelain tile, marble, and granite. At first glance, the product appears to be well-made and durable. However, after using it on a few different surfaces, I have mixed feelings about its performance. One issue I came across is that the 20mm (13/16 inch) size is limited in its use. It seems to be ideal for smaller holes, but when attempting to enlarge a larger hole, the bit struggled to keep up. Additionally, the bit tended to get clogged easily, especially when working with tougher materials like granite. On the positive side, the diamond coating did seem to help with faster and smoother cuts. The finger design also made it easier to control and maneuver the bit. However, I do think that the product could be improved with a wider range of bit sizes and a stronger mechanism for preventing clogging. Overall, I would give the Raizi Diamond Finger Milling Bits a 3-star rating. While it has some noteworthy features, it does have room for improvement in terms of the size and clogging issues.
