The HiKoki CARBON BRUSH (CC14STD) 370779 is a graphite electrical contact set for the HiKoki CC14STD 14-inch chop saw. These brushes are crucial for transmitting current to the motor's rotating part, and this specific model is known for high performance, long-term usage, and a spark-free operation. The part number 370779 identifies this particular carbon brush set for the CC14STD model. Features and function

• Function: These are sliding electrical contacts that transfer current between stationary wires and the rotating motor shaft in the CC14STD chop saw.
• Material: Made from graphite, which provides high performance and efficient conductivity.
• Compatibility: Designed specifically for the HiKoki CC14STD model chop saw.
• Performance: High-quality, original-grade brushes that help ensure the motor operates efficiently and with minimal sparks. 

When to replace

• Worn down: Replace when the brushes wear down to about a quarter of their original length.
• Damaged: Replace if they show signs of burning, crumbling, or breakage.

The Hikoki Carbon Brush with part number 999021 (No. 21) is a specific replacement part for a wide range of Hikoki (formerly Hitachi) power tools, most notably the PDA100 series angle grinders. Key Details

• Function: The carbon brush is a sliding contact made of graphite material that is used to transmit electrical current to the rotating part (armature) of a motor, ensuring proper function and spark-free commutation in DC machines.
• Material: It is typically made from a carbon/graphite compound (H grade or electrographite material) designed for long life, cool running, and negligible sparking.
• Compatibility: This specific brush (part 999021) is compatible with numerous Hikoki/Hitachi models, including but not limited to:
  • Angle Grinders: PDA100D, PDA100K, PDA100M, G10SS, G10SR2, G12SR2, G13SS.
  • Planers: P20SB, P20ST.
  • Shears/Nibblers: CE16SA, CN16SA.
  • Blowers: RB40SA, RB40VA.
  • Other Tools: D10YB, F-20A, GP2, WR16SA, C8FSE, C8FSHE.
• Maintenance: Carbon brushes are wear-and-tear items and need to be inspected regularly (every 3 to 6 months) and replaced when they are worn down to about a quarter of their original length or show signs of burning or breakage to avoid motor damage.
• Packaging: They are typically sold in pairs (one set).
