Case Study
Body SCM440 ø6.9 (5D) drilling
Even when its tool life was extended by 20% beyond the current setting of competitor's, KDA showed less shoulder wear and remained in good cutting edge condition. (Customer evaluation)
Mold parts Cold tool steel ø5.1 (3D) drilling
KDA has smaller variation in hole diameter compared to competitor's products, achieving high-precision machining.
The machining noise was quiet and the chip condition was good.

Nozzle SUS304 ø5.5 (3D) drilling (finished to ø6.0 in post-process)
KDA achieves stable machining of stainless steel and 2.3 times Tool life
Competitor's product was unstable due to Sudden fracture.
(Custome revaluation)
Competitor's product was unstable due to Sudden fracture.

Shaft SUS630 ø5.1 (3D) drilling
KDA achieves stable machining and 1.2 times Tool life
Competitor's products are unstable, so two tools are required for one work lot.
KDA was able to handle it with just one.
