Feature
Balancing rigidity and chip evacuation
Realises deep hole drilling up to L/D=7
High-rigidity Holder Design
Proprietary flute design balances chip evacuation and holder rigidity at a high level. Machining vibration is effectively suppressed and cutting force reduced to realise stable deep hole drilling.
Dedicated Insert Design
The central and peripheral insert designs have been individually optimised, improving stability with the optimal shape and relative positioning. In addition, the wiper flat shape has been optimised to achieve excellent machined surface quality.
Insert Combinations
Utilising different chipbreakers for the central and peripheral inserts enables the drilling of stainless steel and general structural rolled steel.
