Galvanically isolated quick-change chucks
Back
Before

Our specially developed, galvanically isolated quick-change chucks can be attached to hand-held screwdrivers and built-in spindles and enable the use of insulated sockets and bits. The galvanic isolation and the insulated jacket surface effectively reduce the risk of contact with live components, prevent dangerous short circuits caused by high electrical currents and protect battery modules from unintentional short circuits.

Torque range

Our quick-change chucks cover a torque range of max. 25Nm to max. 150Nm ab.
The drive torque is absorbed on the drive side via
a square, while an output side is used on the internal hexagon.
This construction enables quick, safe and efficient tool holding for various applications.

1. 4kt.-1/4″, max 25Nm

2. 4kt.-3/8″, max 35Nm

3. 4kt.-3/8″, max 65Nm

4. 4kt.-1/2″, max 150Nm

Structure

In the insulating core, the electrical conductivity between the screw and the tool is completely interrupted, enabling galvanic isolation in the axial direction. A freely rotating outer sleeve provides radial insulation and offers an insulated and galvanically isolated mounting solution.

1. Electrically isolated connection

2. Insulated plastic jacket surface

3. Quick-change chuck

Product advantages

System design & flexibility

Inexpensive variant to create electrical isolation between the screwdriver and the screwdriving point during screw fastening

Performance & ergonomics

Protection of workers and screwdrivers from electrical voltage

Process integration & operational safety

When the sleeve is touched with the operator’s hand or collides with the component, the sleeve stops. This prevents injury to the hand or damage to the component.

Technical properties

Tested in all applicable areas of standards DIN EN 50178:1998-04 and DIN EN 62477-1:2017-10

Electrical isolation between drive and output shaft
Jacket surfaces on the straight output are electrically isolated
Both outer sleeves are mechanically decoupled from the basic tool
Since the quick-change chuck is exclusively mounted on the output square, the concentricity is analogous to the classic quick-change chucks

Area of application

Screwing applications in the high-voltage range
Hand-guided or hand-held screw connections with or without position monitoring
