Luo ke 8 Pcs Diamond Grinding Bits, Stone Carving Sets for Rotary Tools 2.35MM & 3MM Shank

The Luo ke 8 Pcs Diamond Grinding Bits are advertised for stone carving and use with rotary tools. However, customer feedback indicates that they may not work as well for certain purposes, such as rounding off the sharp edges on jewelry prongs, although they do appear to work well on wood. The bits are said to be suitable for detail carving on hardwood, however, they may not be effective on soft metals such as silver and gold. The cup-shaped burr is reportedly not very effective and has very few grits embedded. Warm prompt instructions for increasing the lifespan of the bits are unclear, with some customers suggesting that using water or oil may help depending on how the bits are used. Overall, the Luo ke 8 Pcs Diamond Grinding Bits set may be suitable for certain projects but may not work well for others.
