Achieve exceptional batch-to-batch repeatability and speed up toolroom cycle times when handling long bar stock or shaft components with industrial-grade Length Stops (internal spindle backstops). Specially engineered to seat deeply within the drawtube or spindle bore of conventional and CNC lathes, this adjustable bar stop system establishes a rigid mechanical reference point for raw stock. Outfitted with an extended adjustment rod and custom lockable clamping collars, it prevents material push-back during high-feed axial turning, drilling, and heavy face-cutting, eliminating manual positioning errors and safeguarding part consistency.
