Frequently Asked Questions
Q: What rotary tools are these diamond grinding bits compatible with?
A: These bits feature a standard 2.35 mm (3/32") shank, making them compatible with most popular rotary tools including Dremel-style handpieces and similar multi-tools. Always confirm your tool's collet size before use.
Q: Can these T-head diamond bits be used on materials other than stone and glass?
A: Yes! While they excel on hard materials like stone, jade, glass, and ceramic, the diamond-coated T-head profile is also effective for detailed grinding and shaping on other hard surfaces such as tile and hard plastics. They are not recommended for soft metals or wood.
Q: What does the "ultra-thin" T-head design offer over standard grinding bits?
A: The 1 mm thin T-shaped head allows you to reach into narrow grooves, tight channels, and intricate carved areas with precision that thicker or bulkier bits cannot achieve — making this set ideal for fine engraving, detail work, and slot-cutting in stone and glass.
Q: How do I get the longest life from these diamond grinding bits?
A: Use at moderate rotary speeds with light, consistent pressure. Keep the work area and bit cool by working in short passes or using a small amount of water as coolant when appropriate for your material. Avoid forcing the bit — let the diamond abrasive do the work.
