0.5mm 100pcs Round Ball Shape Diamond Burs

The 2.35mm Shaft Diamond Round Ball Shape Burs are engineered for smooth contouring, hollowing, and detailed sculpting on hard materials like glass, ceramics, gemstones, bone, and hardwoods. Featuring a spherical tip with galvanically bonded diamond grit, these burs excel in creating rounded grooves, concave surfaces, and intricate 3D designs with precision.

Key Features

• Ball-Shaped Tip: Ideal for curved surfaces and soft transitions in gemstone cabochons or glass art.

• Diamond-Coated Durability: Long-lasting performance on Mohs 6–10 materials.

• Multi-Shank Compatibility: 3mm or 6mm shanks fit rotary tools, flex shafts, and CNC machines.

• Heat Resistance: Stable up to 15,000 RPM with coolant assistance.

Applications

• Lapidary & Jewelry: Shape opal cabochons or carve jade pendants.

• Glasswork: Hollowing stained glass or polishing crystal sculptures.

• Industrial Crafting: Deburr metal alloys or refine composite molds.

Technical Specifications

• Tip Diameter: 0.5mm-10mm.

• Grit Options: 80# (coarse) to 400# (ultra-fine).

• Max RPM: 15,000 (use with water cooling).

Why Choose These Burs?

• Versatility: Perfect for artistic detailing and industrial finishing.

• Efficiency: Faster material removal than silicon carbide or aluminum oxide.

• Precision Control: Spherical design minimizes accidental gouging.

Usage Guidelines

1. Cooling: Use water or coolant to extend tool life.

2. Speed: Start at 5,000 RPM for brittle materials like glass.

3. Pressure: Apply light, steady force for optimal results.

4. Safety: Wear goggles and masks.
