HSK-A collet chuck

ERmillingdrilling

Product overview The HSKA-ER places the widely used ER collet system on a short, lightweight HSK-A interface. One holder family supports drilling, reaming, tapping and milling while maintaining the axial and radial repeatability required at higher spindle speeds and enabling fast tool changes.

Key features

• HSK-A short-taper interface with ER collet clamping.
• ER collet system for flexible tool clamping and wide tool compatibility.
• Compact, lightweight design for high-speed machining and quick tool changes.
• Suitable for drilling, reaming, tapping and milling with consistent axial and radial repeatability.

Precision & balancing

• Dynamic balancing grade: ≤ G1.
• Tool holder run-out accuracy (holder): ≤ 2 μm.
• Combined run-out accuracy: ≤ 5 μm.

Technical data Technical data and performance specifications (including balancing and run-out information) are provided in the product technical-data graphics on the product page.
