Precision-Ground HSK63F/SK20 Tool Holder with Multi-Spec CNC Compatibility

High-performance 42CrMo alloy steel construction, hardened to HRC48-52 for extreme wear resistance. Mirror-polished taper surface (Ra≤0.4μm) ensures 0.003mm maximum runout accuracy. Interchangeable with DIN69893/ISO7388 standards for universal CNC compatibility.

Optimized internal coolant channels (dual 4mm ports) reduce heat buildup during high-speed machining (15,000+ RPM). ER32/ER40 collet chuck options available for milling, drilling, and tapping operations.

Ideal for aerospace aluminum milling, automotive die casting, and precision mold manufacturing. Includes anti-corrosion nitride coating for prolonged tool life in coolant-heavy environments.

Batch-tested with ISO9001 certification. Bulk order discounts available for OEM machine shops and industrial suppliers.
