Our new product line includes a high precision type and a general type for
machining holes in aluminum alloys!
● DAL type for high precision machining is capable of making IT class 7–8 holes.
● DDL type for general hole machining is capable of making IT class 11–12 holes.
It is mainly used for machining holes for taps.
