4.52 / .1780 Valve Guide Reamer Engine

This high-precision valve guide reamer is designed for processing valve guides. Made from high-quality Cold work High speed tool steels, it ensures precise and smooth reaming, improving engine performance and the longevity of the valve system.

Key Features:

• Precision Reaming: The reamer provides an exact diameter and smooth surface inside the valve guides, reducing friction and improving efficiency.
  
  
• High-Quality Material: Made from Cold work High speed tool steels for durability, wear resistance, and high-temperature performance.
  
  
• Hardness: The reamer has a hardness of HRC ±62, ensuring long-lasting sharpness and resistance to wear even with intensive use.
  
  
• Spiral Flutes: give a smooth, even cut Ra < 1,25, ensuring high-quality reaming and reducing friction during use with different materials.
  
  
• Ergonomic Design: Easy to use, suitable for both manual and machine applications, allowing for quick and accurate work.
  
  
• Versatility: Ideal for reaming valve guides in various engine types, carburetors, small generators, and even worn door hinges.
  
  
• Smooth Guide pilot: helps to better is piloted for self-centering action, which ensures easy, precise reaming and improves work with various materials.
  
  
• Improved Performance: Helps achieve precise guide dimensions, reducing valve wear and improving their operational efficiency.
  
  
• High Wear Resistance: The use of high-quality materials ensures the reamer’s longevity, retaining sharpness even during extensive use.
  
  
• Suitable for Various Holes: Ideal for reaming holes in valve guides, carburetors, small generators, and for restoring worn door hinges. The reamer works efficiently with medium-sized holes that require high precision and a smooth cut.

An essential tool for professional mechanics and auto service shops, as well as for use with carburetors, small generators, and worn door hinges.
