To repeat drilling for equally–spaced holes, specify the number of repeats
in K_.
K is effective only within the block where it is specified.
Specify the first hole position in incremental mode.
If it is specified in absolute mode, drilling is repeated at the same position.
Number of repeats K The maximum command value = 9999
If K0 is specified, drilling data is stored, but drilling is not performed.
When an M code specified in parameter No.5110 for C–axis clamp /
unclamp is coded in a program, the CNC issues the M code for C–axis
clamp after the tool is positioned and before the tool is fed in rapid traverse
to the point–R level. The CNC also issues the M code for C–axis unclamp
after the tool retracts to the point–R level. The tool dwells for the time
specified in parameter No. 5112.
To cancel a canned cycle, use G80 or a group 01 G code.

CAUTION
In each canned cycle,
R_ (distance between the initial level and point R) is always
handled as a radius.
Z_ or X_ (distance between point R and the bottom of the
hole) is, however, handled either as a diameter or radius,
depending on the specification.
