WTE NC quick-change drill chuck (DIN 69871 Form A) — 2.5–16 mm, SK40

The WTE NC quick-change drill chuck (DIN 69871 Form A) is a precision clamping solution for CNC machines and machining centres that enables fast, in‑machine tool changes while maintaining tight runout tolerances.

• SK40 shank DIN 69871 Form A
• Clamping range 2.5–16 mm
• Runout accuracy max. 0.02 mm
• In‑machine quick tool change

Consistent spindle performance through precision design

The holder is manufactured as a precision unit with a SK40 taper to DIN 69871 Form A, delivering a short, rigid and vibration‑free assembly that improves spindle behaviour under load. The integrated shank and chuck configuration minimises overhang and resonance, which, combined with a specified runout accuracy of max. 0.02 mm, reduces tool deflection and rework. This is particularly beneficial in serial production where cumulative tolerances affect part quality and where repeatable concentricity saves machining time and scrap.

Faster, safer tool changes while the workpiece stays in place

A conical drive mechanism operated via a laterally inserted cross‑handle pin wrench allows for a quick, uncomplicated tool change directly in the machine. The design prevents the chuck from opening during rotation or in the event of an abrupt spindle stop, maintaining clamp security and reducing the risk of loose tooling. By shortening tool change cycles and avoiding complete spindle disassembly, machine utilisation increases and setup downtime is reduced — a clear logical benefit for high‑mix, medium‑volume production.

Compatible, versatile clamping for a wide range of operations

With a clamping range of 2.5–16 mm and a compact chuck diameter of 57 mm, this quick‑change chuck accepts a broad variety of drills and shank sizes commonly used in drilling and light reaming operations. The unit is specified for both clockwise and counterclockwise rotation, widening its application to multi‑axis setups and reversing processes. Where a compact, robust holder is required for machining centres, the short overall length supports obstructed or tight fixturing situations without compromising stability.

Practical maintenance and workshop advantages

The precision build reduces inspection intervals driven by poor concentricity, and the straightforward mechanical actuation simplifies daily handling. The robust construction and avoidance of in‑run opening lower the chance of accidental tool release, contributing to a safer workplace and fewer unplanned interruptions. For procurement, sourcing through a dependable distributor ensures consistent availability and a clear supply chain; Metav Werkzeuge provides a quality filter for European workshops and can assist with specification matching and logistics.

FAQ

What is the maximum runout accuracy of this chuck?
The WTE NC quick‑change drill chuck achieves a runout accuracy of max. 0.02 mm, ensuring consistent concentricity for drilling and light reaming tasks.

Which spindle taper is required to use this holder?
This chuck is designed for SK40 taper to DIN 69871 Form A, making it compatible with machining centres and CNC spindles specified to that standard.

How is a tool change performed in the machine?
Tool changes are carried out by engaging the conical drive with a laterally inserted cross‑handle pin wrench, allowing a fast, in‑machine procedure without removing the holder from the spindle.

Can the chuck be used for both rotational directions?
Yes, the chuck is specified for both clockwise and counterclockwise rotation, permitting use in processes that require reversing or multi‑axis operations.

What clamping range does the chuck cover?
The clamping range is 2.5–16 mm, covering the common drill and shank diameters used in many workshop and production environments.
