Industrial SCN1-IK-86 HSK-A63-BZ18 Tool Holder

Bilz SCN1-IK-86/HSK-A63-BZ18 Tool Holder is a precision CNC tool holder designed to fit HSK-A63 spindles, part of Bilz’s robust family of tool-retention components. The 63 mm nominal body diameter and 86 mm overall length (L1) define a compact, rigid interface intended for stable tool engagement in milling and drilling setups. It carries a stated tolerance of ±0.15 mm and uses the BZ18 locking interface variant (BZ18-BL) for secure retention of HSK-A63 tooling. Marketed under the SCN1-IK-86 designation, this model aligns with Bilz’s modular clamping system and standardized interfaces to support repeatable setup in production environments. In practical CNC applications, the combination of a tight ±0.15 mm tolerance with a true HSK-A63 interface helps maintain tool runout and concentricity, contributing to consistent surface finish and dimensional accuracy during high-precision machining.
