CNC Tool Bar Internal Hole Boring Tool – Precision Machining Solution
High-precision boring bar for internal hole machining with superior rigidity and vibration resistance. Features replaceable carbide inserts (S10K/S12M/S16Q/S20R/S25S-SDQCR/L07/11) for extended tool life and consistent performance. Engineered with hardened alloy steel shank for exceptional durability under heavy-duty cutting conditions. Ultra-fine grinding ensures micron-level accuracy, ideal for tight-tolerance boring in automotive, aerospace, and mold manufacturing. Modular design allows quick interchangeability for multiple bore sizes. Anti-chatter geometry minimizes deflection, delivering smooth finishes in stainless steel, cast iron, and hardened alloys. Optimized coolant channels enhance heat dissipation during deep-hole operations. Trusted by CNC professionals for high-efficiency production runs with repeatable results. Global wholesale pricing – bulk orders available at unbeatable rates. Stock up for your workshop with the industry’s most cost-effective precision tooling.
