The GPS guide pad is primarily used for tool guidance and support in deep hole drilling systems, controlling the stability of the cutting tool and suppressing vibration, without directly participating in the cutting process. It is typically used in combination with BTA deep hole drill bodies and shanks, to maintain bore straightness and improve hole surface quality, especially crucial for long-reach deep hole machining with high length-to-diameter ratios. It is suitable for automotive components, hydraulic cylinder parts, mold and die manufacturing, oil & gas equipment, aerospace components and heavy machinery processing.
