8 * 8.5 * 13.5 mm Power Tool Carbon Brush Graphite Brush Replacement

Power Tool Carbon Brush Graphite Brush Replacement (8×8.5×13.5 mm)

This is a replacement carbon brush for power tools, made of graphite material with dimensions of 8×8.5×13.5 mm (length × width × height). It is compatible with various power tools such as angle grinders, electric drills, and rotary hammers from multiple brands.

Key Details:

1. Product Type: Carbon Brush
   A core consumable component in motors that conducts electrical current to the rotor via contact with the commutator, enabling motor rotation. The graphite material offers both electrical conductivity and self-lubrication, reducing friction and wear.

2. Dimensions: 8×8.5×13.5 mm
   These precise dimensions ensure a perfect fit into the tool’s brush holder, providing stable contact. Commonly compatible with mainstream power tools of the same size specification, such as certain Bosch, DeWalt, and Makita models.

3. Compatibility:

• Angle grinders (e.g., 115mm/125mm compact models).

• Electric drills/impact drivers (e.g., 12V/18V cordless drills).

• Rotary hammers/stone cutters and other power tools.

4. Replacement Indicators:

• Replace when the carbon brush wears down to half its original length (approximately 6-7mm).

• Symptoms like excessive sparking, power loss, or unusual noise may indicate poor brush contact or depletion.

Usage Tips:

When replacing the carbon brush, verify the original brush dimensions of your tool and clean any dust from the brush holder and commutator surface to ensure optimal conductivity and service life.
