6-Piece Diamond Grinding Needle Burrs Set

Dull carving bits, chipped gemstone edges, and rough detail cuts shouldn't spoil your fine lapidary work or intricate crafting projects. Shape, carve, and polish ultra-hard materials effortlessly with our 6-piece diamond grinding needle burrs set, engineered with electroplated diamond grit and standard 2.35 mm shanks for precision rotary tool work.

Crafted with high-density industrial diamond particles electroplated over hardened alloy steel shafts, these micro-grinding bits provide exceptional wear resistance and aggressive cutting power. The set includes fine head diameters ranging from 1 mm to 4 mm, giving you the exact precision needed for micro-carving, engraving fine lines, expanding small holes, and smoothing contours. Fitted with standard 2.35 mm (3/32 in) shanks, these burrs fit smoothly into most rotary tools, jewelers' flex shafts, micro-motors, and die grinders for detailed work on glass, jade, ceramics, stone, and metals.

Key Features

• 6-Piece Multi-Size Precision Set: Includes needle burrs with head diameters from 1 mm to 4 mm for fine detail carving and hole enlarging.

• Industrial Diamond Particle Coating: High-density electroplated diamond grit cuts smoothly through hard materials like jade, glass, tile, and hardened steel.

• Standard 2.35 mm Shank Fit: Features 2.35 mm (3/32 in) shanks compatible with Dremel rotary tools, dental drills, flex shafts, and micro-grinders.

• High-Precision Needle Geometry: Tapered needle profile provides pinpoint accuracy for detail engraving, signature etching, and cavity cleaning.

• Heat & Wear-Resistant Alloy Steel: Hardened steel shaft core prevents bending and resists thermal stress under high rotational speeds.

• Versatile Lapidary & Craft Utility: Ideal for gemstone carving, glass etching, ceramic tile trimming, stone sculpting, mold polishing, and jewelry making.

Why Choose Our Diamond Grinding Needle Set Unlike standard steel or carbide burrs that dull instantly on hard mineral surfaces, our electroplated diamond needle burrs maintain sharp cutting edges across ultra-hard materials. They deliver smooth, controlled material removal without chipping.
