Precision Carbide Tiny Boring Bar MTR with Through Coolant – High-Performance Inner Hole Machining
Ultra-durable solid carbide construction ensures exceptional wear resistance and extended tool life for demanding operations. Advanced through-coolant design maximizes heat dissipation, reducing tool deflection and improving surface finish in deep-hole boring applications. Micro-grain carbide substrate paired with a razor-sharp cutting edge delivers superior precision for tight-tolerance machining of small-diameter holes. Optimized chip evacuation geometry prevents clogging during continuous high-speed operations. Ideal for aerospace components, medical instrument manufacturing, and precision automotive parts where flawless inner bore quality is critical. Compatible with CNC lathes and Swiss-style machines for versatile deployment. Engineered for stainless steel, hardened alloys, and exotic materials—offering unmatched stability in heavy-duty production environments. Mirror-polished flutes minimize friction while coated variants (upon request) enhance thermal resistance. Global wholesale pricing with bulk discounts—supply your workshop with industry-leading tools without compromising quality. No MOQ restrictions, direct factory shipments ensure cost efficiency.
