Precision CNC Boring Bars for Micro Hole Drilling

High-performance tungsten carbide construction ensures extreme durability and wear resistance for long-lasting precision. Ultra-fine micro boring capability perfect for delicate machining tasks requiring sub-millimeter accuracy.

Mirror-polished cutting edges reduce friction and deliver clean, burr-free finishes in hardened materials. Ideal for aerospace components, medical device manufacturing, and watchmaking precision work.

Patented MTR coating technology enhances heat dissipation and prevents built-up edge formation. Compatible with high-speed CNC machining centers and manual bench drilling setups.

Engineered for rigid stability during deep-hole operations with reinforced shank design. Essential toolset for mold makers, instrument repair technicians, and automotive fuel injector maintenance.

Direct-from-factory pricing with bulk order discounts available. Ships globally with certified quality inspection reports included.
