SCHUNK WELHSKA WELDON end mill holders with HSK40A, HSK50A, HSK63A, HSK80A, HSK100A DIN ISO 12164-1 shanks for clamping of cylindrical shank tools, Weldon shank diameter and length of your choise
(Incl. Tax: €142.74)
This WELDON tool holder is designed for securely clamping cylindrical shank tools, preventing torsion and pull-out thanks to a lateral locking screw. It complies with DIN 1835B and DIN 6535HB, ensuring a run-out ≤ 0.003 mm measured from the cone, and is balanced for speeds up to 25,000 rpm (G2.5 or Umax < 1 gmm). Equipped with a G1 thread for the clamping screw and chip pocket holes conforming to DIN 69873, it supports automatic tool changes. The Cool Flow version features peripheral coolant channels, directing coolant to the cutting edge for optimal performance. The supply includes the WELDON clamping screw.

The Weldon tool holder with HSKA interface is designed to ensure secure and extremely stable clamping of cylindrical shank tools with a lateral clamping surface, delivering top-level performance in the most demanding machining operations. Thanks to its side screw locking system, compliant with DIN 1835B and DIN 6535HB standards, the holder effectively prevents both torsion and accidental tool pull-out, guaranteeing reliable and constant torque transmission even under heavy cutting conditions. The locking screw, supplied as standard, simplifies use and ensures precise and safe tool seating.
From a technical perspective, this tool holder provides a run-out accuracy of ≤ 0.003 mm measured from the taper, enabling high-precision machining and excellent surface quality while minimizing tool wear. The balancing grade G2.5 at 25,000 rpm or Umax < 1 gmm makes it suitable for high-speed applications, where vibration reduction and dynamic stability are essential to ensure efficiency, precision, and durability over time.
The HSKA interface, widely used in modern machining centers, guarantees rigidity and reliability in power transmission, as well as stable and repeatable tool positioning. These features make the Weldon tool holder particularly suitable for heavy milling, roughing, contouring, and any application requiring high torque and maximum safety against slippage.
Key application areas include the automotive industry, aerospace, mold and die manufacturing, and precision engineering, where robust, precise, and reliable tool holders are crucial even for the most demanding machining tasks. With its combination of precision, strength, and compliance with international standards, the Weldon tool holder with HSKA interface is the ideal choice for professionals and operators seeking operational safety and consistent quality in production.
