Custom Modular Tool Holders / Replaceable Head Tool Holders
Overview
Aoshiji® Custom Modular Tool Holders are designed to provide maximum flexibility, precision, and cost efficiency in modern CNC machining. Featuring a replaceable head system, they allow fast tool changes, reduced machine downtime, and extended holder body life. This makes them the ideal choice for aerospace, automotive, mold and die, and precision component manufacturing, where adaptability and productivity are critical.
Applications
Aerospace machining requiring long-reach stability and high rigidity
Automotive milling and drilling with precision tolerance control
Mold and die manufacturing using interchangeable cutting heads for multiple operations
High-mix, low-volume production where frequent setup changes are required
CNC machining environments needing cost-efficient modular tooling
Key Features
Modular design – Replaceable cutting heads for different geometries and operations
Enhanced rigidity – Precision-ground holder body with optimized balance for stability
Cost efficiency – Extend tool holder life by replacing only the cutting head
Coolant-through capability – Supports internal coolant for better chip evacuation and tool life
High precision – Runout accuracy ≤ 0.003 mm ensures stable cutting performance
Benefits
Lower tooling costs by using interchangeable heads on one body
Higher productivity with quick head changes and reduced downtime
Improved machining accuracy through stable clamping and precise runout control
Extended tool body service life compared to conventional holders
Versatility – Adaptable for drilling, milling, boring, and custom machining operations
