Weldon flat clamping arbor DIN 69893A HSK-A63 – 10 mm clamping, 100 mm length (TECWERK)

A Weldon flat clamping arbor DIN 69893A HSK-A63 designed for secure clamping of tools with cylindrical shanks and lateral drive flats, suitable for high-precision CNC milling applications

• Weldon side drive for axial retention
• HSK-A63 interface for high-speed spindles
• 10 mm clamping diameter for cylindrical shanks
• 100 mm overall length for extended reach

Faster set-ups through precise HSK connection

The HSK interface significantly reduces runout and increases repeatability compared with conventional taper holders. The HSK-A63 connection ensures a rigid, axial and radial fit during both torque and centrifugal loads, which shortens set-up time and reduces rework. With the hollow shank taper DIN 69893 Form A design, the arbor seats positively in the spindle, improving concentricity and enabling consistent clamping accuracy for serial machining tasks. These mechanical benefits translate directly into higher throughput and lower scrap rates on production lines.

Secure axial retention with Weldon side drive

The Weldon flat provides mechanical axial retention for tools with a lateral drive face per DIN 1835-B, preventing end-play under heavy cutting forces. This side-drive arrangement complements the HSK taper by offering a secondary retention principle that is particularly valuable when machining at elevated feed rates or when interrupted cuts occur. The combination of taper seating and Weldon drive reduces the risk of tool pull-out and helps maintain tool orientation, thereby preserving cutting edge life and process stability.

Compatibility and practical dimensions for workshop use

Key dimensions support versatile application: clamping Ø 10 mm for standard cylindrical shanks, an external diameter of 35 mm and an overall length of 100 mm provide balance between reach and rigidity. The arbor is specified with bore tolerance H4, which standardises the fit with Weldon-style tools and supports interchangeability across tool inventories. For machine shops seeking a compact yet robust holder, this solution integrates with HSK-A spindles and common milling tool stocks without compromising stiffness.

Reduced downtime through straightforward maintenance and fitting

The design focuses on pragmatic maintenance: the hollow-shank taper facilitates easy cleaning of the seating surfaces and the Weldon flat is a proven, low-maintenance retention method. Regular inspection of seating faces and flats prevents contamination-related runout. When installed and maintained according to spindle and toolholder guides, the arbor supports predictable tool life and fewer unplanned tool changes, contributing to a stable production schedule and lower total process cost.

FAQ

Which spindle types are compatible with this arbor?
The arbor is made for HSK-A spindles and fits HSK-A63 interfaces; the Weldon flat clamping arbor DIN 69893A HSK-A63 works with spindles designed for DIN 69893 Form A toolholders.

What shank styles can be clamped with this holder?
Tools with cylindrical shanks and a lateral drive flat according to DIN 1835-B are compatible; the holder's 10 mm clamping diameter secures such shanks reliably.

How does the Weldon feature improve safety during machining?
The Weldon side drive provides mechanical axial retention in addition to the taper fit, reducing the chance of tool pull-out during heavy cuts or interrupted machining.

Is the bore tolerance specified for accurate tool interchange?
Yes, the arbor is supplied with bore tolerance H4, supporting consistent fits and interchangeability across matching tool shanks.

Can this holder be used for high-speed machining?
The HSK-A63 interface and the hollow shank taper DIN 69893 Form A are engineered for high-speed applications where precise seating and reduced runout are required; ensure spindle specifications and balancing procedures are followed.
