Start with the written lesson below.
What you’ll learn
- Identify mandrels, bands, and common bit materials.
- Explain why shape and abrasiveness both matter.
- Describe careful handling and maintenance.
Lesson
Mandrels and sanding bands
A mandrel holds a compatible sanding band. Bands come in different abrasiveness levels and are typically single-use. Check secure fit and equipment compatibility before operation.
Diamond, carbide, and ceramic
Diamond bits use an abrasive surface. Carbide and ceramic bits commonly use cutting flutes for enhancement tasks. Material alone does not tell you whether a bit is appropriate for natural nails or skin; check the specific design, grade, and manufacturer guidance.
Shape follows purpose
Barrels, cones, and other shapes provide different contact areas. A rounded end does not make a tool risk-free. Inspect bits for wear or damage, process reusable bits according to their instructions, and store them protected.
