Reducing machine downtime through quick head replacement
Tool changes are possible without removing the body from the machine. No tool length adjustment is required, achieving high repeatability accuracy through a unique clamping mechanism.
Reducing tool inventory costs by switching to head exchangeable tools
Solid drills require resharpening or recoating processes. Considering the lead time on such processes, extra inventory must be maintained.
Head exchangeable drills can remove these resharpening processes and reduce investments on tools as well as improve cash flow.
