Nikken HSK100A-SK16-105P-J-IDU HSK 100 Collet Chuck, 3-16 mm, 105 mm, Coolant-Through

The Nikken HSK100A-SK16-105P-J-IDU is a high-precision slim chuck collet holder designed for drilling, milling, and reaming applications. It features an HSK100A taper shank and utilizes the SK16 collet system, which employs a steep 8-degree taper to provide double the clamping force and precision of traditional 16-degree ER collet systems. This model is equipped with a titanium nitrided (TiN) bearing nut that improves cutting rigidity, surface finish, and sliding effect while preventing corrosion and micro-vibration. The tool holder supports a 5-micron run-out guarantee at four times the diameter and is compatible with high-pressure coolant systems, featuring a unique coolant-thru design for higher accuracy and gripping torque. Its narrow body design allows for improved access to tight spots and hard-to-reach areas. The SK16 system accommodates tool shank diameters ranging from 2.75 mm to 16.0 mm. Specific technical dimensions for this variant include a 1.575-inch nose diameter and a 105 mm projection length. The construction involves sub-zero treatment to -90°C to ensure 100% martensite composition, preventing deformation and deterioration over time.
