SK COLLET SYSTEM DESIGN & BENEFITS
SK Collets are suitable for a wide range of applications, from milling to reaming. Standard collets can be used in coolant thru applications (with coolant back-up screws). Increased Gripping Power The smaller the taper angle is, the better concentricity is obtained. Our steep 8° collet seats deeper in the body of the holder, providing twice more clamping force and twice more precision than traditional 16° ER collets.
8° collet = double gripping force & dampening
BENEFITS OF HIGHER GRIPPING FORCE • Machining with higher chip load reduces cycle time • Prevents end mill pull-out, reducing scrap rates • E limination of over tightening reduces collet damage and excessive runout • More optimal overall cutting conditions

SK Collet vs. ER Collet
A. Slim design allows for clearance B. F orce is perpendicular to centerline of toolholder for strong grip C. Deep position creates greater accuracy D. Rigid body is flush
A. Wide collets = wide nut design B. Force is angular to centerline of toolholder C. Shallow position creates collet rocking D. Body diameter is smaller than nut compromising rigidity
