241-4559 Road Milling Cutter Holder PM200 Asphalt Milling Machine Wear Resistant Tool Holder Parts

The 241-4559 road milling cutter holder is designed for PM200 asphalt milling machines in road paving and rehabilitation projects. This wear-resistant OEM tool holder spare part holds the milling cutter firmly in the milling system, extending tool life and lowering maintenance cost.

• Heavy-duty 241-4559 asphalt milling cutter holder for PM200 milling machines.
• Wear-resistant steel construction withstands abrasive road milling conditions.
• Accurate tolerance fit for quick replacement and reduced machine downtime.
• Heat-treated surface resists deformation in continuous asphalt paving work.
• OEM spare part supplied direct from the factory for road construction fleets.

• Part number 241-4559 is a critical wear component on the drum of a 2-meter road milling machine, used to hold milling teeth and protect the base block beneath them. This tool holder features a plug-in quick-change design with a tapered fit that self-locks during operation—the harder it cuts, the tighter it grips—while a knock-out hole allows fast tooth removal.

  Material and Process
  The holder body is typically forged from AISI 4140 or 42CrMo alloy steel, then quenched and tempered to 42–50 HRC, balancing impact toughness with wear resistance. The finished tapered bore forms an interference fit with the tooth shank, with a standard 30° taper and an interference of 0.08–0.12 mm, ensuring the tooth rotates freely during cutting without loosening.

  Key Technical Parameters
  The bore diameter is usually 20 mm, matching round-shank milling teeth of the same shank size. Fit accuracy directly affects service life: if the fit is too loose, tooth life drops by 30–50% and holder replacement frequency doubles. A wear indicator groove on the holder shoulder allows visual assessment of remaining life. Hydraulic pressing is recommended during installation, with axial force controlled at 3,500–4,500 N to avoid interference deviation caused by hammering.

  Use and Maintenance
  The milling tooth must rotate freely inside the holder; once it seizes, holder wear accelerates sharply. Regular spraying with a water-based asphalt emulsifier helps remove buildup and maintain rotation, extending life by 20–40%. If grooves appear on the holder bottom face, replace it promptly to prevent damage to the drum base.
