TECWERK Weldon Face Clamping Holder DIN 69871 Form AD – SK40, 10 mm clamping diameter, 50 mm projection

The TECWERK Weldon Face Clamping Holder DIN 69871 Form AD is a SK40 taper tool holder designed to secure cylindrical‑shank cutters with a lateral Weldon drive flat, providing standardised mounting for conventional and CNC spindles.

• Weldon flat for positive lateral drive
• Steep taper DIN 69871 Form AD
• Clamping diameter 10 mm H4 tolerance
• SK40 taper compatibility

Consistent concentricity for precision machining

The steep taper interface DIN 69871 Form AD paired with a defined H4 bore tolerance ensures a close, repeatable fit between spindle and holder. That dimensional accuracy reduces radial runout and provides consistent repeatability across tool changes, which improves surface finish and prolongs cutter life. The Weldon drive flat contributes to secure torque transmission without relying solely on friction, so rotational accuracy is preserved under load.

Broad compatibility with cylindrical‑shank cutters

Designed for tools with a cylindrical shank and lateral drive flat to DIN 1835‑B, this holder accepts a clamping diameter of 10 mm, with an overall diameter of 35 mm and a projection length (A) of 50 mm. The SK40 taper makes the holder suitable for many machining centres and toolholders, enabling quick integration into existing setups. This compatibility helps maintain machining flexibility while keeping tooling standardised.

Practical advantages for the workshop and production line

The compact design and standard conformity facilitate straightforward inspection and replacement planning. With clear dimensional references—D = 35 mm, A = 50 mm, clamping Ø = 10 mm—maintenance routines can be standardised and spare parts stocked sensibly. The positive lateral drive and standard taper support reliable high‑precision operation in short‑ and medium‑run production, delivering operational confidence and reduced setup variability.

FAQ

What shank types are compatible with this holder?
The TECWERK Weldon face clamping holder is made for cylindrical‑shank cutters with a lateral Weldon drive flat according to DIN 1835‑B; it secures a 10 mm shank.

Which taper does the holder use?
The tool holder uses an SK40 taper and complies with DIN 69871 Form AD, ensuring compatibility with matching SK40 spindles and adaptors.

What is the clamping tolerance and why does it matter?
Clamping bore tolerance is H4, which ensures a precise fit and improved concentricity for repeatable machining accuracy with minimal radial runout.

Can the holder be used in CNC machining centres?
Yes, the combination of SK40 taper, Weldon drive flat and standardised dimensions makes this holder suitable for both conventional and CNC machines requiring defined tool engagement.

How long is the projection and how does it affect rigidity?
Projection (A) is 50 mm; a shorter projection generally increases rigidity, so this compact length balances reach with stability for many workshop applications.
