The Nikken Slim Collet, also known as the SK Collet, is engineered for compact, high-precision CNC operations. Designed to minimize overhang and interference, it allows access to narrow or restricted machining areas. Despite its slim profile, it delivers excellent holding power and minimal runout, enabling ultra-accurate results in fine milling, micro drilling, and engraving. Manufactured in Japan with precision-ground alloy steel, this collet type is widely used in mold & die, aerospace, electronics, and medical manufacturing where detail and finish quality matter most.
