The Weldon Slim tool holder with SK40 interface is designed to ensure secure and precise clamping of tools with a lateral driving flat on cylindrical shanks, making it ideal for machining operations that require stability, reliability, and a slim profile to access hard-to-reach areas of the workpiece. Thanks to the lateral clamping screw system, the tool holder effectively prevents both torsion and accidental pull-out of the tool, even under demanding cutting conditions, thus maintaining constant and safe operation.

Compatible with tools in compliance with ISO 1835B and ISO 6535HB standards, this tool holder fully meets international requirements and guarantees versatile use with the highest precision demanded by modern milling applications. The supply includes both the spherical head clamping screw and the axial adjustment screw, essential for optimizing tool positioning and clamping, ensuring a stable and long-lasting connection.

From a technical standpoint, the Weldon Slim holder offers a run-out accuracy of ≤ 0.003 mm measured at the taper, enabling outstanding dimensional accuracy and superior surface finishes. Its balance grade of G6.3 at 8,000 rpm or Umax < 1 gmm provides high stability during medium- to high-speed operations, reducing vibrations and protecting both the tool and the machine spindle from premature wear.

The slim design of the Weldon Slim with SK40 makes it particularly suitable for applications in sectors such as precision mechanics, aerospace, automotive, and mold making, where accessibility and precision are key requirements. The combination of structural rigidity, reliable clamping, and compact geometry makes this tool holder an essential choice for professionals, technicians, and operators requiring consistent and safe performance in demanding milling operations.
