Industrial 99-717-W Spindle Extension

Smith Tool's Industrial 99-717-W Spindle Extension is a precision spindle accessory that lengthens the reach of compatible machine spindles for industrial milling and drilling applications. Identified by the part number 99-717-W and branded SMITH TOOL, this extension sits within the manufacturer's line of spindle-related accessories designed for professional machining environments. By adding axial length to a spindle assembly, it provides deeper tool engagement and increased clearance between tooling and surrounding fixtures, guards, or workholding devices. The 99-717-W designation signals a purpose-built component intended to satisfy demanding production workflows where extended reach is necessary to access tight or recessed features without compromising spindle alignment. This extension supports maintaining consistent tool-path accuracy during longer reach operations, contributing to stable cutting performance and repeatable results in everyday shop tasks. As an industrial-grade component, it is intended for use in production settings that require reliable, long-term tool extension performance.
