Weldon end mill holder SK40 (DIN 69871 Form AD) – 14 mm clamping diameter, 100 mm projection | TECWERK

The Weldon end mill holder SK40 (DIN 69871 Form AD) is a tool-holder solution for secure clamping of cylindrical-shank cutters with a lateral drive flat, designed for integration in milling spindles and machining centres.

• DIN 69871 Form AD taper
• SK40 steep taper compatibility
• 14 mm clamping diameter H4
• 100 mm projection length

Secure clamping that reduces setup variability

The holder delivers consistent tool retention through a steep taper to DIN 69871 Form AD combined with a dedicated Weldon flat, ensuring axial and radial security for tools with a cylindrical shank. The combination of taper fit and lateral drive means the tool is held by both taper contact and the side drive, which reduces micro-movement under cutting loads and supports repeatable set-ups. Such mechanical reliability translates into fewer interruptions on the shopfloor and a higher effective uptime for production runs.

Clear machine compatibility and straightforward integration

Built to accept cutters with a side drive per DIN 1835-B, the holder adapts easily to machines equipped with the corresponding spindle taper. The SK40 specification and the dimensional data—100 mm projection and 44 mm body diameter—allow planners to check reach and clearance quickly. The internal bore is manufactured to H4 tolerance for the clamping seat, supporting accurate concentricity for a 14 mm clamping diameter; this precision assists in maintaining acceptable runout and extending tool life when used with appropriately matched tooling and spindle conditions.

Practical benefits for workshop efficiency and handling

Handling and inspection are made straightforward thanks to the familiar Weldon-style configuration, which simplifies tool changes and visual verification of the lateral drive. The holder’s geometry enables reliable torque transmission without reliance on adhesive measures, supporting safer, predictable machining processes. As a component from TECWERK, it integrates industry-standard dimensions and mounting practice, making it suitable for manufacturers and toolrooms seeking a durable, standards-compliant tool-holding option that eases logistics and reduces the need for special adapters.
