CYLINDRICAL SHANK WITH FLAT SECTION JIS B 4005 (ISO3338-2) The following standard shank is required for MEGA PERFECT GRIP.
0 -.011 0 -.013 0 -.016
• JIS Standards require sizes ø25 or higher to be double-flat types. The MEGA Perfect GRIP does not use a rear flat surface, but is capable of clamping double flat shanks. • JIS B4005 has the same dimensions as International Standard ISO3338-2 and German Standard DIN1835-1. In case you are adding your own flat, the tool projection length in the MEGA PERFECT GRIP will be decided by the flat position. Refer to H 1 in the MEGA PERFECT GRIP chart, decide the flat position to add, and then cut the cutter at L 1 on cutter shank. ! CAUTION
