Rigid reamer (10.00-13.00 mm)

  • Performance enhancement and environmental protection: Valve guide reamers are crucial for improving the engine performance, reliability and environmental friendliness of combustion engines by optimizing sealing, reducing wear and friction and thus helping to reduce emissions.
  • High quality materials and precision manufacturing: Our rigid valve guide reamers are made from high-quality HSS/E steel and comply with ISO fit H7. Their spiral grooving and the long guide piece at the lower end ensure precise machining results.
  • Innovative design for efficient handling: Unique is the upper end with a hexagon socket (except for sizes below 4.5 mm), which allows easier handling as the reamer can be removed directly from the lower end of the guide and does not have to be moved backwards.
  • Improved operability and efficiency: In contrast to manual operation with a reversible tool, the use of a hexagonal bar in combination with a low-speed hand drill enables faster and more reliable processing.

Rigid valve guide reamer with hexagon socket

The use of valve guide reamers has a significant influence on the performance, reliability and environmental friendliness of an internal combustion engine. Thanks to the precise machining of the valve guides, they improve sealing, reduce wear and friction, increase engine performance and contribute to a reduction in emissions. 

Our rigid valve guide reamers are made of high quality HSS/E steel with ISO fit H7. They are spiral-grooved and have a long guide piece at the lower end, while a hexagon socket is fitted at the upper end instead of the usual square (except for sizes < 4.5 mm). This allows the reamer to be removed from the lower end of the guide – it does not have to be moved backwards. With a hexagonal rod, the reamer can be operated by a slow-running hand drill.

This process is much faster and more reliable than operating the reamer by hand with a turning tool.

Your advantages

Precise fit: Valve guide reamers enable precise machining of the valve guides to ensure an optimum fit between the valve and guide. This is important to ensure reliable sealing and smooth operation of the engine.

Improved performance: By using valve guide reamers, tight tolerances can be achieved, which can lead to improved engine performance. A precise fit reduces friction and wear, which has a positive effect on the performance, efficiency and durability of the engine.

Reduction of oil consumption and smoke development: A precise fit of the valve guides using reamers can help to reduce oil consumption. A poor fit can result in oil entering the combustion chamber, which leads to smoke development and increased oil consumption. This problem can be solved by using valve guide reamers.

Extension of the service life: Correct machining of the valve guides with reamers can help to extend the service life of the valves and valve guides. Wear is reduced and the valves are prevented from loosening or jamming.

Easier maintenance: A properly machined valve guide makes it easier to maintain the engine. If valves or valve guides need to be replaced, this can be done more easily and more precisely if the valve guides have been machined correctly.

Reduced emissions: A correctly machined valve guide area helps to prevent leaks and thus reduce emissions. Lower emissions are not only more environmentally friendly, but can also play a role in compliance with emission standards and legal regulations.
