TECWERK Weldon face clamping holder — DIN 69871 Form AD, SK40, clamping Ø 16 mm

TECWERK Weldon face clamping holder for SK40 spindles, designed to take cylindrical‑shank tools with a lateral drive surface to DIN 1835‑B and to provide secure, repeatable clamping for milling and drilling operations on vertical machining centres

• Weldon shank for positive lateral drive
• Steep taper DIN 69871 Form AD
• Clamping diameter 16 mm
• SK40 spindle taper, 45 mm body diameter

Secure positive drive for high‑torque operations

The Weldon lateral drive design transmits torque positively via a side clamping flat, reducing slippage under heavy cut conditions. That mechanical engagement, combined with the 16 mm clamping diameter, supports tools with cylindrical shanks to DIN 1835‑B, so torque transfer is direct and reliable. For workshops seeking predictable performance, this form of positive drive simplifies tool selection and minimises downtime caused by slippage or premature tool change‑outs.

Precision taper for concentricity and fast tool changes

The holder uses the steep taper DIN 69871 Form AD, which establishes axial seating and repeatable concentricity on the SK40 interface. A correctly seated taper reduces radial runout and improves surface finish and tool life; the bore tolerance H4 noted for the clamping bore contributes to consistent grip and alignment. For production runs where repeatability matters, the steep taper delivers fast changeover with measurable stability from one cycle to the next.

Compact dimensions that integrate easily into existing setups

Measured dimensions of A = 35 mm projection and D = 45 mm body diameter make the holder compact enough for tight tool arrangements while providing sufficient mass for stable clamping. The combination of the SK40 spindle interface and a 16 mm clamping capacity enables direct replacement of common Weldon holders without extensive fixture alterations. This physical compatibility reduces retrofit time and keeps the machine back in productive use sooner.

Practical benefits for workshop productivity

By pairing a positive lateral drive with a precision taper and a tight clamping bore, the holder offers improved tool retention and consistent repeatability—factors that reduce scrap, rework and machine idle time. The simple mechanical principle behind the Weldon flat keeps maintenance straightforward, and the standardised interfaces mean the holder integrates with established tool inventories and collet systems. For operations focused on throughput and reliability, this configuration supports steady production flow.

FAQ

What shank types are compatible with this holder?
The TECWERK Weldon face clamping holder is designed for tools with a cylindrical shank and a lateral drive flat to DIN 1835‑B and will accept such tools securely at the 16 mm clamping diameter.

How does the DIN 69871 Form AD taper affect repeatability?
The steep DIN 69871 Form AD taper of the holder ensures axial seating on the SK40 spindle, improving concentricity and reducing radial runout for more consistent machining results.

Is the clamping bore tolerance critical for performance?
Yes. The clamping bore specified with H4 tolerance maintains tight grip and alignment, which contributes to reliable tool retention and repeatable positioning during production.

Can this holder be used directly in machines with SK40 spindles?
The holder is manufactured for SK40 interfaces and is intended for direct installation on compatible spindles without additional adapters, matching common workshop standards.
