Flächenspannfutter (Weldon) – SK40 holder with 16 mm clamping

Flächenspannfutter (Weldon) – SK40 designed for secure holding of tools with cylindrical shank and lateral drive flat, suitable for machining centres and toolroom spindles

• Weldon flat for secure lateral drive
• SK40 steep taper to DIN 69871 Form AD
• Clamping diameter 16 mm
• Bore tolerance H4 for precise fit

Greater process reliability through positive drive and standardised taper

The combination of a Weldon lateral drive flat and a SK40 steep taper to DIN 69871 Form AD ensures positive torque transmission and repeatable seating in the spindle. This design reduces slippage under load and supports consistent spindle concentricity, which is essential when high positional accuracy is required. The standardised taper simplifies tool change compatibility across machines that conform to DIN 69871, reducing set-up uncertainty and downtime.

Accurate clamping and concentricity for predictable results

A defined 16 mm clamping diameter together with a H4 bore tolerance provides a tight, measurable fit between holder and tool shank. This predictable interface minimises runout and contributes to improved surface finish and longer tool life. For operations where dimensional consistency is critical, the precise bore tolerance and robust clamping geometry translate directly into fewer rejects and more stable production cycles.

Compact design that supports efficient tool handling

With an overall body diameter of 48 mm and an axial length A of 63 mm, the holder offers a compact footprint while maintaining stiffness for standard milling and drilling tasks. The form and dimensions allow efficient access in crowded tool magazines and compact spindle noses without compromising clamping strength. The configuration suits workshops seeking a pragmatic balance between space-saving design and dependable tool retention.
