Frequently Asked Questions
Q: What types of drill bits are best for cutting through glass, tile, and stone?
A: Diamond-tipped drill bits are the gold standard for cutting through hard, brittle materials like glass, ceramic tile, marble, and granite. Unlike standard HSS bits, diamond drill bits use abrasive diamond particles to grind through the material rather than cutting, which reduces cracking and chipping. Our 10-Pc Diamond Drill Bit Set covers sizes from 6mm to 32mm, making it suitable for a wide variety of hole-drilling applications.
Q: What is a diamond cutting wire and what is it used for?
A: A diamond cutting wire is an ultra-thin wire coated with diamond abrasive particles, designed for precision manual cutting of delicate or hard materials such as jade, gemstones, glass, and stone. The thin diameter (available in 0.25mm, 0.4mm, 0.45mm, and 0.5mm) allows for intricate cuts with minimal material waste — ideal for lapidary work, jewelry making, and fine stone crafting. Explore options like our 0.25mm Diamond Cutting Wire for the finest precision cuts.
Q: What grit abrasive wheels should I use for polishing metal?
A: For metal polishing and finishing, the grit you choose depends on your starting surface condition. Coarser grits (e.g., 80–120) are best for initial deburring and removing scratches, while medium grits (180–240) refine the surface, and fine grits (320+) deliver a smooth, polished finish. Our 100-Pack Abrasive Buffing & Polishing Wheels includes five different grits so you can work through the full finishing process with one convenient set.
Q: Can I use grinding discs and cutting wheels with a rotary tool like a Dremel?
A: Yes! Many of our abrasive discs and cutting tools are compatible with rotary tools such as Dremel devices. For example, our 10-Pc Diamond Cutting Disc Set for Dremel Rotary Tools is specifically designed to fit standard rotary tool mandrels, making it easy to cut, grind, and engrave a wide range of materials with precision and control.
Q: How do I attach polishing or grinding wheels to a drill or angle grinder?
A: Connecting abrasive accessories to your power tool is straightforward with the right adapter. Our 1/4" Hex Shank M14 Drill Adapter (10 Pack) bridges the gap between standard drills and angle grinder attachments, giving you the flexibility to use polishing pads, grinding wheels, and other M14-threaded accessories with a regular drill. Always ensure your tool's RPM rating is compatible with the accessory before use.
