The structural analysis of the tool removed unnecessary parts, and the application of the Lattice shape resulted in about 30% lighter weight compared to the previous one. In addition, it is possible to achieve smooth chip discharge and increase product life by setting the number of inserts in consideration of chip discharge and machining load.

Lightweight allows high-speed rotation, high cooling effect through cooling channels increases cutting efficiency, and allows machining the difficult-to-cut materials at higher quality.

The optimal cooling channel was applied by analyzing the flow of chips and heat generation during drilling machining. The cooling channel with the DFAM technique can create a free cross-sectional shape and path, so it has a higher cooling effect than the existing tool.

Drilling Tool, which has an excellent cooling effect, enables deep hole machining and contributes to increasing product life. In addition, it is good at machining difficult-to-cut materials due to the smooth discharge of chips.
