Diamond Drill Bit Round Blades Set (5 Discs + Mandrel)

Precision Diamond Drill Bit Round Blades for Versatile Cutting

This Diamond Drill Bit Round Blades Set is designed for users who need accurate, clean grinding and slotting across a wide range of materials. Each disc features a diamond-coated cutting edge bonded to a metal core, delivering controlled material removal rather than aggressive cutting. The set is compatible with most standard handheld rotary tools and drills when used with the included mandrel.

The 22 mm (0.87 inch) discs are ideal for detailed work in tight or narrow spaces, making them suitable for tasks such as flush cutting, slotting, trimming and fine adjustments. The diamond coating provides consistent performance on hard and abrasive surfaces, including stone, cement, tile, marble, ceramics, glass, carbide, fiberglass, plastics, soft metals and more. This makes the set practical for workshop use, DIY projects, model making, small-scale metalworking, and light construction or renovation tasks.

Why It's a Smart Choice

• Versatile material compatibility - Effectively grinds and shapes stone, tile, glass, ceramics, plastics and soft metals, reducing the need for multiple specialized discs.
• Precise work in confined areas - Compact 22 mm discs are well-suited for fine detail work, slots, and flush trimming where larger blades cannot reach.
• Cost-efficient set configuration - Includes five diamond-coated discs plus one 3.8 cm mandrel, allowing multiple replacements and continuous use on a single drill or rotary tool.
