58mm Cross Groove Adapter Milling Arbor HSK-A63 With 27mm Clamping, Hollow Shank DIN 69893 Form A - TECWERK

Combining a DIN 69893 Form A hollow-shank taper with an enlarged collar and front-face coolant channels delivers improved stability and chip evacuation for consistent milling accuracy; order directly via Metav Werkzeuge or ask their consultants for specification support.

Side-slot mounting arbor DIN 69893 Form A, HSK-A63 by TECWERK — 58 mm body, 27 mm clamping

A Side-slot mounting arbor DIN 69893 Form A engineered to hold cutter heads and side-slot cutters according to DIN 1880, offering a robust HSK-A63 interface for milling applications.

• Hollow shank taper DIN 69893 Form A
• Front coolant channel drillings
• Enlarged collar diameter for stability

Increased process stability through geometry and mass

The arbor is designed with an enlarged collar diameter and substantial body mass to reduce vibration and improve tool life during interrupted cuts. This geometry increases clamping rigidity when fitted into an HSK-A63 spindle, resulting in steadier cutting forces and more consistent surface finish. The combination of stable support and precise concentricity makes this toolholder suited to demanding milling where minimal runout is critical.

Better coolant delivery and chip control for longer tool life

Additional coolant channels drilled into the front face direct cutting fluid close to the cutting edges, improving lubrication and chip evacuation at the point of contact. For operations using cutter heads or side-slot cutters, efficient cooling reduces thermal load and helps prevent built-up edge, which in turn extends insert and cutter life. Explained simply: targeted cooling keeps cutting geometry stable, which preserves tolerances and lowers rework rates.

Simple compatibility and safe clamping for production use

Built to DIN 69893 Form A with a hollow shank taper, the arbor accepts standard HSK toolholding practice while enabling swift tool changes and reliable torque transmission. The toolholder is intended for cutter heads and cutters with the side-slot specification DIN 1880, so adapters or bespoke fixtures are not required in many workshop setups. This compatibility supports streamlined tool management and reduces setup complexity on CNC milling centres.

FAQ

What spindle interface does this arbor use?
The arbor uses an HSK-A63 interface and is manufactured to DIN 69893 Form A for compatibility with HSK-A63 spindles.

Which cutter types can be mounted on this arbor?
It accepts cutter heads and side-slot cutters that conform to DIN 1880, enabling direct mounting without custom adaptors in many setups.

How do the coolant channels affect machining performance?
Front-face coolant channels deliver fluid close to the cutting zone, improving lubrication, chip evacuation and thermal control, which helps maintain tool geometry and prolong tool life.

Is this arbor suitable for heavy interrupted cuts?
The enlarged collar diameter and robust body design increase clamping rigidity and vibration damping, making the arbor well suited to demanding milling operations.

Can the arbor be used in automated tool-change systems?
Yes; the hollow shank taper and HSK-A63 interface are compatible with automated tool-change systems that accept DIN 69893 Form A toolholders.
