AN-111 SUNNEN Standard Cylinder Hone

Review SUNNEN Aftermarket Standard Portable Cylinder Hone 2.5 Inch 7.0

The AN-111 Sunnen Standard Cylinder Hone, model 2.5-7.0, is a precision machining tool designed specifically for honing cylinder bores in engines. This hone is an essential part of the engine rebuilding process, ensuring that the cylinder walls are perfectly round and true for optimal engine performance.

The AN-111 Sunnen Standard Cylinder Hone features a robust and durable design, with a high-quality carbon steel body and precision-machined abrasive stones. The stones are arranged in a unique and effective pattern, which includes a tapered leading edge and a series of parallel lands, providing superior honing results. The hone comes with four different abrasive stones of varying grit sizes (120, 220, 400, and 600), allowing for progressive honing and the removal of metal buildup and engine deposits.

The hone's handle is ergonomically designed for comfort and ease of use, providing a secure and firm grip. The handle also features a convenient adjustment mechanism, which allows for precise control of the hone's position within the cylinder bore. This ensures that the hone is always in contact with the cylinder wall, providing consistent and even honing.

The AN-111 Sunnen Standard Cylinder Hone is also equipped with a unique cooling system, which circulates engine oil through the hone during the honing process. This not only helps to keep the hone and the cylinder walls cool but also lubricates the honing process, reducing friction and wear on the cylinder walls.

The hone's dimensions are 22 inches long and 3 inches in diameter, making it suitable for use in engines with cylinder bores ranging from 2.5 to 7.0 inches in diameter. The hone comes with a detailed instruction manual and is backed by Sunnen's industry-leading warranty, ensuring that users have the confidence and support they need to complete their engine rebuild projects with precision and confidence.
