Precision Diamond-Coated Boring Cutter for Micro Hole Perfection

Industrial-grade PCD (Polycrystalline Diamond) cutting edge ensures extreme durability and razor-sharp precision for high-speed machining. Ultra-fine 0.3-3mm diameter range handles delicate engraving and deep hole boring in hardened materials like carbon fiber, MDF, and non-ferrous metals.

Unique long-neck design reaches 50mm depth with stability, eliminating tool deflection during intricate router bit operations. Electroplated diamond particles provide 10x longer lifespan than standard carbide bits for mass production environments.

Ideal for CNC routing, jewelry mold making, circuit board milling, and aerospace component fabrication. Mirror-finish cutting surface requires zero polishing for finished parts. Compatible with Makita, Bosch, and Dewalt plunge routers.

Wholesale-priced professional tool meets JIS B4051 standards. Bulk packages available for factory production lines. Minimum order quantity starts at 50 units with express global shipping.
