⚡ At a Glance
  • Conductivity: Low electrical resistance and stable power transfer under load
  • Best for: DIY enthusiasts, small workshops and maintenance technicians needing quick brush replacements
  • Not ideal for: Tools that require proprietary or non-standard brush dimensions

A 50-piece kit supplied in ten commonly used sizes, with five pieces per size. Carbon-graphite construction and flexible copper leads allow straightforward replacement across a wide range of power tools.


Longer motor life - With high-purity carbon-graphite material

High-purity carbon-graphite composite lowers electrical resistance and tolerates higher temperatures, reducing arcing during commutation. Precision manufacture minimises uneven wear on commutators while maintaining stable conductivity.

Reduced sparking helps preserve commutators and maintain motor output over time, keeping tools performing closer to original specification.

Fast, hassle-free swaps - With pre-attached flexible copper leads

Each brush includes a flexible copper lead already attached, removing the need for soldering or fiddly wiring during installation. The leads are shaped for typical brush holders used in hand-held and stationary tools.

Quick installation gets tools back in service sooner, reducing workshop downtime and the need for specialist fitting tools.

Ready stock for repeated fixes - With ten size options and five pieces each

The set contains ten different sizes, from smaller and narrower brushes to larger formats, with five identical pieces supplied per size. Sizes cover many common motor brush dimensions encountered in household and professional tools.

Having multiple spares on hand means several repairs can be completed before a reorder, making maintenance more convenient and predictable.
