Innovative coating process significantly increases the clamping force by 75% compared to standard ER collet nut. More gripping force provides better rigidity and reduces the possibility of losing grip on the round shank which lead to expensive damage on cutting tools and work piece material. Internal clamping ring's shape is design to minimize out-of-balance compare to the standard off-center o-ring design from other standard ER collet nut, achieving 12,000 RPM without needed to drill holes on the collet nut body when placed on a dynamic balanced machine to preserve ER collet nut's body strength. Slot geometry is design with different length to offset uneven weight distribution from the inner o-ring.The face of the ER collet nut is precision ground to achieve visual appeal.
