JAPAN PAT. TOOLING SYSTEM (triple contact) can be done on the BT double face contact spindle.
1. Power of Dampening Effect.
Performance enhancement due to the dampening effect are already universally recognized when using Nikken's DREAM-CUT Holder. - Extended tool life of 3 to 5 times.
(MBT) Dampening Effect - Stable Cutting

2. The mechanism which generates the excellent cutting performance -Internal Expanding Pressure System
・ Tool clamping mechanism that use a disc springs experience lower clamping force during continuous use. ・ is a system for locking the maximum pulling force that is instantly produced during tool pulling. ・ Cutting torque is greatly reduced compared to BT tooling for more comfortable cutting. Internal Expanding Mechanism System for instantly locking the maximum pulling force
