- Seating deeper into the pocket and smaller overhand creates greater accuracy- High gripping torque due to 8 degree taper- SK collet is pushed into the pocket without twisting by a flat shoulder, thus force is perpendicular to the centerline of the tool holder for strong gripping- Rigid collet body is flush with nut to maintain rigidity- Shoulder Collet edge seats flush with the front surface of collet nut to maintain strong rigidity- Shoulder on the front of the collet prevents chip packing or stringy bird nests below the collet chuck nut of extend tooling life
8 Degree SK collet seats deeper in the pocket than 16 degree taper ER collet, providing twice more clamping force and twice more accuracy during high speed machining. Collet edge seats flush with the front surface of collet nut to maintain strong rigidity. Bearing nut reduces twisting of the collet and improve accuracy.
