Series 317 Large Diameter Boring System

Highly precise, rigid and safe to operate

The Series 317 Large Diameter Boring System is designed for heavy roughing of bores. The compact rugged configuration makes it ideally suited for use on production machines such as boring mills and machining centers with spindle taper sizes of 40 and larger.

The modular components such as flange, extension slide, tool holder and boring head, can easily be assembled to single cutter, twin cutter and pin turning tools.


New components with safety screws can be mounted on existing extension slides without any restrictions whereas the safety screws must be removed. Existing components without safety screws can as well be mounted without any restrictions on the new extension slides.


On request, safety screw modifications can be made to existing precision boring heads and extension slides to prevent tool breakage from accidentally high spindle speeds.
