Introduction of case studies on cost reduction for end mill reuse and tool modification.

Introducing a case where a no longer needed end mill was reused to successfully improve work processes.

We would like to introduce a cost reduction case where we successfully improved operations by repurposing unused end mills into stepped drills. After performing the pilot hole cutting, we found that the secondary operation of chamfering the end face resulted in poor work efficiency due to the two-step process. Upon reviewing the process, we determined that it would be better to modify the tool into a drill rather than an end mill, and we proposed tool recycling from our company. By reusing the shank of the used end mill and adding new cutting edges, we transformed it into a stepped drill capable of both drilling and chamfering in one operation. As a result, we consolidated the two processes of drilling and chamfering into one, thereby improving work efficiency. [Concerns Before Modification] ■ Poor work efficiency due to performing chamfering after pilot hole cutting, resulting in two operations. *For more details, please refer to our catalog or feel free to contact us.*
