Carbon/electrographite motor brushes Dedra XDED7941.18 — set of 2 replacement brushes

Replacement electrographite (carbon) motor brushes Dedra XDED7941.18 — set of 2 replacement brushes designed to restore electrical contact between the rotating commutator and the stationary brush holders in compatible motors and power tools. These electrographite brushes are supplied as a matched pair and are intended for maintenance and repair tasks where original or equivalent carbon brushes are required to reestablish reliable conductive contact and reduce sparking and wear on the commutator.

Advantages

Electrographite material provides stable conductivity and a surface finish that is compatible with common commutator materials, helping to reduce intermittent contact and electrical noise. Supplied as a set of two, the brushes simplify replacement of both sides of a motor at the same time to ensure even wear and balanced operation. The design and material selection prioritize wear resistance and consistent electrical transfer under typical operating loads for compatible Dedra tools and similar equipment.

Suitable for

• Repair and maintenance of small electric motors that use carbon or electrographite brushes.
• Replacement in hand-held power tools and workshop equipment compatible with Dedra brush form and dimensions.
• Servicing appliances and devices that exhibit poor contact, sparking, or reduced performance due to worn brushes.

When it may not be suitable

These brushes are intended for motors that accept electrographite/carbon brush types; they may not be suitable for devices that require different brush shapes, spring assemblies, or specialized materials such as metal-impregnated or silver-graphite variants. Correct fit and contact pressure are essential—using brushes with incorrect dimensions or spring tension can cause poor performance or increased wear.

Key specifications

• Material: electrographite (carbon)
• Pack quantity: set of 2 brushes
• Intended use: commutator/brush-type motors and compatible power tools
• Main properties: conductive, wear-resistant sliding contact suitable for brush-commutator interfaces

How to use

Turn off and disconnect the equipment from the power source before beginning any work. Access the motor brush holders by removing the tool or appliance cover according to the manufacturer’s service instructions. Withdraw the old brushes from their holders, noting orientation and any retaining springs or clips. Install the new electrographite brushes in the same orientation, ensuring the contact surface seats properly against the commutator and any springs or retainers are reinstalled. Reassemble the housing and test the motor at low load to confirm smooth operation and acceptable sparking levels before returning the tool to normal service.

What to consider before purchase

• Verify physical dimensions and mounting style of the brushes in your motor against the replacement to ensure proper fit.
• Confirm that electrographite (carbon) brushes are compatible with your device rather than metal-impregnated or specialty brush types.
• Check whether any retaining springs, holders, or connector parts need replacement at the same time.

Usage recommendations

Replace both brushes of a motor at the same time to maintain balanced commutation; inspect the commutator surface and clean or service it if heavy deposits or grooves are present to ensure optimal contact and reduce wear.
