• Universal arbors for milling cutters with longitudinal or tenon drives (DIN 138).

3. Dimensional and Tolerance Data

• Maximum circular deviation maintained at ≤ 0.008 mm for Morse tapers and ≤ 0.005 mm for modular tooling adapters, ensuring high precision and concentricity.
• Comprehensive tables specify lengths, diameters, thread sizes (M6 to M48), and other critical parameters.

4. Material and Mechanical Properties

• All components are manufactured from case-hardened alloy steel with surface hardness Rc 57-60 for wear resistance and durability under machining stresses.

5. Product Categories and Applications

• Morse Taper Tools: Standard tapers, threaded tapers, and tang tapers for secure tool holding.
• Quick-Change Systems: Optimized for fast tool changes in drilling and tapping; not recommended for milling.
• Collet Chucks: ER type and DIN 6388 compliant chucks with optional balanced and bearing nuts for precision holding.
• Adapters and Extensions: Facilitate adaptation between Morse taper sizes and extend tool reach.
• Universal and Shell Reamer Arbors: Designed for milling cutters and reamers with specific drive types.

6. Operational Recommendations and Limitations

• Maximum rotation speed for quick-change tapping chucks is 2,000 rpm.
• Quick-change holders are not suitable for milling operations.
• A minimum clearance of 10 mm between workpiece and tool is recommended for quick-change systems.
• Adapters and holders maintain maximum concentricity through precise taper coupling.

7. Accessories and Optional Components

• Available accessories include wrenches, balanced nuts, bearing nuts, and ejector nuts to enhance tool handling and performance.
• Complete sets and composition boxes are offered for collets and tooling components.
