These bits feature a standard 1\/8\" (3.17 mm) shank that is compatible with Dremel rotary tools and most other major rotary tool brands. Simply insert the shank into your tool's collet and tighten securely before use.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What materials can I grind or shape with these 120-grit diamond bits?\u003c\/h4\u003e\n\u003cp\u003eA: These diamond grinding bits are well-suited for use on hard materials including glass, stone, ceramic, tile, resin, and hard plastics. The 120-grit diamond coating provides a balance of material removal speed and surface finish quality.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How long do diamond grinding bits typically last?\u003c\/h4\u003e\n\u003cp\u003eA: Longevity depends on the material being worked and the operating speed used. Running the bit at the correct RPM for the material type and avoiding excessive pressure will significantly extend bit life. The electroplated diamond coating on these bits is designed for durability across multiple projects.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use these bits wet or dry?\u003c\/h4\u003e\n\u003cp\u003eA: These bits can be used dry for most applications. When working with glass or tile, a small amount of water can help reduce heat buildup and extend bit life — simply dip the workpiece or bit tip periodically during use.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Are these diamond grinding bits compatible with my Dremel rotary tool?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes!
