SCHUNK ToolholdersToolholders

SCHUNK toolholders by interface and clamping method

Toolholder selection begins with both ends of the assembly: the machine spindle interface and the cutting-tool connection. Heat-shrink, hydraulic, collet and mechanical adapters have different clamping requirements and included components. Compare exact articles rather than only the general technology.

Choose by the application, then the configuration

Confirm the spindle interface and tool-shank requirements before selecting the holder. Compare clamping technology, projection and clearance using the article drawing. Identify any sleeve, extension or coolant component required by the proposed assembly.

Read accuracy and balancing values with the manufacturer’s stated conditions. Confirm the selected configuration’s coolant and interface options rather than assuming they apply to the whole family. Send the exact machine and tool details to our team for a fit review.

Specifications that matter

Review machine interface, clamping diameter, tool shank requirements, projection, clearance and scope of delivery. Read each value with its units and the conditions attached to it. Where the drawing uses a reference letter or subscript, match that reference to the table instead of relying on the apparent proportions of the illustration.

Read drawings and manufacturer documents together

Use the selected product’s technical table, dimension drawing and supporting manufacturer documents together. Check the article or EDP identifier and the document’s stated family or configuration scope. A general catalog page can provide context, but it should not override a current product-specific listing when the two disagree.

Frequently asked questions

Is a clamping nut or actuation key always included?

Review the selected article’s scope of delivery. Included nuts, screws, keys and sleeves differ between product types.

What should match between the tool and holder?

Compare the tool shank with the exact holder’s stated clamping requirements and dimensions. Check the selected article’s instructions for any required sleeves, nuts or other components.

How can I confirm coolant requirements?

Use the selected holder’s published coolant features and applicable installation instructions. Ask Tech Tool to confirm an unstated connection or requirement instead of assuming it is supplied.

Which length should I use when checking clearance?

Match the drawing’s length definitions and reference letters to the specification table. Review the complete tool assembly and machine clearance rather than treating every length as projection.
