Sandhog Locked internal boring tool Boring bar

The Sandhog S16Q-SDQCR11 represents the pinnacle of high-precision, heavy-duty internal boring. Designed for CNC machining centers and high-performance lathes, this locked-style boring bar eliminates deflection and vibration, the primary enemies of tight-tolerance boring, deep-hole machining, and fine surface finishing. Its robust, one-piece "locked" construction ensures absolute stability, making it the ideal solution for demanding materials like high-temp alloys, stainless steels, and hardened steels.

Revolutionary Locked Tool Design: Unlike conventional cartridge-style bars, the S16Q-SDQCR11 features a solid, integrated shank and head. The cutting insert is securely clamped directly into the monolithic body. This design maximizes rigidity by over 300% compared to modular systems, dramatically reducing chatter and allowing for heavier, more productive cuts.

Unmatched Stability for Deep Reaching: The S16Q shank designation indicates an extra-rigid, short-back design optimized for stability. When combined with the SDQCR11 locked head, it provides exceptional reach-to-diameter ratios, enabling you to bore deeper with confidence and maintain critical tolerances.

Precision-Ground Geometry: The integral pocket and seating surfaces are precision-ground to micron-level tolerances. This guarantees perfect insert placement every time, ensuring repeatable accuracy, consistent tool life, and superior surface finishes straight out of the holder.

Optimized for Sandhog SDQCR11 Inserts: Designed specifically for the SDQCR11 insert style (a high-positive, 80° diamond/cosine geometry with a 11/32" IC). This versatile insert geometry offers multiple cutting edges, excellent chip control, and free-cutting action for both roughing and finishing operations.

Enhanced Coolant Delivery: Features dedicated coolant channels engineered to deliver high-pressure coolant directly to the cutting edge. This effectively breaks chips, reduces heat, and prolongs tool life, especially in stringy materials.

Heavy-Duty Construction: Manufactured from premium, heat-treated alloy steel, providing the ultimate strength and fatigue resistance for continuous production environments.
