High Precision Small Hole Bore Reaming Cutter MTR Tungsten Carbide Boring Tool

Ultra-hard tungsten carbide construction ensures extended durability and wear resistance for high-speed operations. Precision-ground cutting edges deliver flawless surface finishes in tight-tolerance applications.

Engineered for mini/micro lathe machines, ideal for watchmaking, jewelry crafting, and precision instrument repair. Micro-groove design reduces friction while maintaining chip clearance during deep-hole boring.

Heat-treated steel shank provides superior stability, minimizing vibration during high-RPM drilling. Compatible with CNC and manual lathes for versatile workshop use.

Mirror-polished flutes prevent material buildup, ensuring consistent performance in aluminum, brass, and soft steel alloys.
