GG25-DM85 SUNNEN Diamond Honing Stone Set

Review SUNNEN Aftermarket 80mm Diamond Honing Stone Set

The GG25-DM85 Sunnen 80mm Diamond Honing Stone Set is a premium set of honing stones designed for precise and efficient engine cylinder bore finishing. This set, manufactured by Sunnen Products Company, a leading innovator in engine honing technology, includes six stones, each carefully calibrated to deliver consistent and accurate honing results.

The set comprises six honing stones - fourProgressive Diamonds and two Rat Tail plates. The Progressive Diamonds stones feature progressive grit sizes: 240, 400, 600, and 800 grit. These stones are engineered with a unique diamond crystal structure that provides excellent cutting ability and durability. Diamond crystals are universally recognized for their unparalleled cutting capacity and their ability to produce a mirror-like finish on cylinder walls.

The first stone in the set, the 240 grit, is designed for heavy stock removal and rapid material reduction. The 400 grit stone is employed for fine cutting and serve as a transition between the initial cutting stones and the smoothing stones. The 600 grit stone finishes the cylinder walls while minimizing scratches and preparing the cylinder for the ultimate finishing stones.

The two Rat Tail plates in the set are designated for the final honing process. The first Rat Tail plate features a 1000 grit ceramic finish that polishes the cylinder walls for an exceptionally smooth surface. The second Rat Tail plate features a 3000 grit ceramic finish which results in a mirror-like finish, ensuring that the cylinder walls are optimally prepared for the engine oil and compression rings.

These stones are accompanied by Sunnen's renowned roller-type honing plates, which ensure even and consistent contact between the stone and cylinder walls - ensuring a superior finish with minimal operating effort.

The GG25-DM85 Sunnen 80mm Diamond Honing Stone Set is a valuable asset for engine builders, machine shops, and automatic transmission rebuilders looking to deliver top-quality finishes to their engine cylinders. With precise grit sizes and durable diamond crystals, this set ensures accurate bore finishing and significant time savings in the honing process.
