Unlike generic bits that may shed abrasive particles, these are engineered for consistent performance. The stainless steel construction ensures heat resistance and durability, crucial for prolonged use in India's varied workshop conditions.

Ideal for Detailed Craftwork & DIY
These bits are perfect for gemstone carving, molding repair, cleaning castings, rust removal, and general polishing. They are also suitable for nail art, shaping natural or artificial nails.
