Review SUNNEN Keyway Honing Mandrel Hard Guide Shoes And Stones

Introducing the SUNnen AAY20-869BH Keyway Honing Mandrel Shoes and Stones, a must-have accessory for any professional automotive engine builder or race shop. These high-performance honing mandrel shoes and stones are specifically designed to provide precise and efficient keyway honing for crankshafts and connecting rods, ensuring optimal engine performance and longevity.

The SUNnen AAY20-869BH Keyway Honing Mandrel Shoes come as a set, consisting of three pairs of shoes in various sizes to accommodate a wide range of crankshaft bore sizes. Each pair of shoes features a unique keyway design that engages with the corresponding keyway on the crankshaft or connecting rod, allowing for accurate and consistent honing. The shoes are made from high-quality, heat-treated steel that ensures durability and longevity, even during the most demanding honing sessions.

The accompanying stones are designed to work seamlessly with the mandrel shoes, providing a range of grit sizes to suit various honing applications.

This range allows for efficient and precise honing of keyways, ensuring a perfect fit and smooth operation.

The honing process is made easier with the inclusion of a flexible mandrel, which provides the necessary flexibility to conform to the contours of the crankshaft or connecting rod. This ensures a consistent and even honing process, reducing the risk of damage to the components. The mandrel is also designed to be easily adjustable, allowing for quick and precise positioning of the stones for optimal honing results.
