6.5*13*22 MM Carbon Brush Replacement Parts for Power Tools Electric Graphite Brush

Replacement Parts for Power Tools Electric Graphite Brush 6.51322 MM Carbon Brush

Key Information Analysis:

1. Product Attribute: Electric Graphite Brush for Power Tools
   Primarily composed of high-purity graphite (some contain a small amount of metal to enhance conductivity), the graphite material endows it with excellent self-lubrication and electrical conductivity. It can stably conduct current during high-speed operation while reducing wear on the motor commutator, making it suitable for high-frequency usage scenarios of power tools.
2. Compatibility Range:
   Based on the 6.5×13×22mm specification, it is suitable for brushed motors of medium-power power tools. Common applicable scenarios include:
   • Handheld power tools: such as medium-sized electric drills, angle grinders, grinders, reciprocating saws, etc.;
   • Portable equipment: some models of jigsaws, polishers, impact wrenches, etc.
     The core of compatibility is that the size must completely match the brush holder of the tool's motor (with an error of ≤0.2mm). In particular, the width (13mm) and thickness (6.5mm) must strictly correspond; otherwise, it may cause loose installation or poor contact.
3. Size Specifications: 6.5×13×22 MM
   This size falls into the category of medium-sized carbon brushes. The length of 22mm allows for a longer service life (compared to small carbon brushes). Dimensional accuracy directly affects the usage effect; excessive errors may cause abnormal motor sparks, abnormal operation noise, or even tool burnout. It is necessary to accurately measure the size of the original carbon brush before replacement.
4. Functions and Roles:
   • Serves as the "core of current conduction" for power tool motors, ensuring efficient current transmission from the power source to the rotor and guaranteeing sufficient output power of the tool;
   • The high-temperature resistance of graphite makes it suitable for short-term overload operation of power tools (such as instantaneous high loads during drilling or grinding), reducing carbon brush failure caused by high temperatures.
5. Replacement Signals:
   The carbon brush should be replaced in time when the power tool shows the following conditions:
   • The carbon brush is worn down to less than 1/3 of its original length (about 7-8mm);
   • There are significantly more sparks at the carbon brush during motor operation, or the tool has a "stuttering" sensation;
   • The output power of the tool decreases, or the rotation speed drops significantly after startup.
