SIKKA Rigid tapping collets are manufactured with an internal square tang that keeps the tap from spinning within the collet during use.
These rigid tapping collets are compatible with taps per DIN, ISO, JIS and ANSI standards.
The SIKKA ER-GB rigid tapping collets are manufactured with an internal square. They are intended for use on CNC machines that have synchronized machine spindle speed and feed rate. Machines that have such “rigid” tapping capabilities do not require the use of axial compensation type tooling.
