y Notes for Use
No Restriction for HoldersRestriction for Holders
Standard holders can be used.*Use a holder with end cutting angle 93° for improving wiper
( A double clamp, high rigidity tool isefficiency. A holder with end cutting angle 91° can improve wiper
recommended.)efficiency, however, there is no wiper efficiency with other end
cutting angles (60°, 90°,107°etc.).
