AUTOMOTIVE THREADED SHANK

FLOATING ROLLER DRIVE HOLDERS

RECOMMENDED FOR REAMING AND

SYNCHRONOUS TAPPING

Holder floats 1/32" in all directions, 1/16" total movement to compensate for parallel misalignments.
Holder can be used in stationary and rotating applications.
Its unique design uses rollers instead of balls to provide friction free movement and prolonged holder life.
Holder is self-centering and has adjustable float tension to compensate for cutter weight.
Holder is completely sealed to eliminate contamination, thus insuring longer holder life.
