Replacement Carbon Brushes for Electric Hammer
These carbon motor brushes serve as direct replacements for worn components in electric hammer drill motors. They are sold as a set of five pairs and are intended for users who need to restore motor performance after brush wear causes poor running. The brushes come with wire leads and springs already attached.
Pre-Assembled Leads and Springs Reduce Assembly Time
Each brush includes the wire lead and brush spring attached, which removes the need to fit these small parts separately during replacement. This design helps prevent lost springs or misaligned leads, which are common issues when rebuilding brush assemblies from loose components. The dark grey and silver tone finish matches the original motor brush appearance.
Simple Slide-In Installation
Installation typically involves removing the motor end cap, sliding out the old brushes, and inserting the new set into the brush holders. The most common problem occurs when the spring tension is not seated correctly, causing intermittent contact or arcing. Ensuring the lead wires are routed clear of rotating parts avoids insulation damage during operation.

Questions about this item
How often will the 12x6x5mm carbon brushes need replacing under normal use?
Carbon brushes are among the most commonly replaced power tool components; worn brushes often cause a poorly running motor, so inspect them regularly and replace when the carbon block wears down.
What dimension limits how long these brushes last in an electric hammer drill?
The carbon brush size of approximately 12 x 6 x 5 mm and total length of 26 mm determine the wear life; once the carbon material erodes past the spring contact, the motor will run poorly.
Do the brushes generate noticeable heat or noise when the drill runs all day?
The brushes themselves produce minimal heat and no audible noise; any heat or sound comes from the motor commutator contact, which is normal for carbon brush operation.
