14 best grit for honing cylinders
Grit for honing cylinders is a crucial component used in automotive maintenance and repair, specifically in the context of honing engine cylinders. Honing is a process that involves the removal of a small amount of material from the inner surface of the cylinder walls to improve their condition. Here's what you should know about grit for honing cylinders:
Purpose: The primary purpose of honing cylinders in an engine is to create a smooth, consistent surface on the cylinder walls. This promotes proper piston ring seating, reduces friction, and ensures efficient engine performance.
Honing Tools: To perform cylinder honing, automotive technicians use specialized tools known as honing machines or honing stones. Honing stones are abrasive tools that contain the grit necessary to remove material from the cylinder walls.
Grit Types: Honing stones come in various grit types, which determine the coarseness or fineness of the abrasive surface. Common grit types include coarse, medium, and fine. Coarse grit removes material quickly but leaves a rougher finish, while fine grit provides a smoother surface.
Material Compatibility: The choice of grit depends on the type of material used in the engine cylinders.Different engine materials may require specific grit types to achieve the desired finish without damaging the cylinder walls.
Cross-Hatching: The honing process often creates a cross-hatch pattern on the cylinder walls. This pattern improves oil retention and helps with piston ring seating.
Lubrication: Proper lubrication is essential during the honing process to prevent overheating and maintain the integrity of the honing stones. Honing oil is commonly used to ensure a smooth and controlled honing operation.
Honing Cylinder Damage: It's crucial for automotive technicians to use the appropriate grit type and technique during cylinder honing. Using the wrong grit or improper honing methods can lead to cylinder damage, affecting engine performance and longevity.
Precision and Skill: Cylinder honing is a precision task that requires skill and experience. Automotive technicians must carefully measure and monitor cylinder dimensions and surface finish to ensure they meet manufacturer specifications.
Engine Rebuilding: Cylinder honing is often part of the engine rebuilding process. When an engine undergoes a major overhaul, the cylinders are honed to restore them to their optimal condition.
Quality Control: Properly honed cylinders are critical for engine efficiency and longevity. Quality control measures are in place to ensure that the honing process is performed accurately and consistently.
In summary, grit for honing cylinders is an abrasive material used in conjunction with honing stones to improve the inner surface of engine cylinders. This process is crucial for maintaining engine performance, piston ring seating, and overall engine efficiency. Choosing the right grit type and using proper techniques are essential to ensure the successful honing of cylinders in automotive applications.

The Flex-Hone® tool was originally created by Brush Research Manufacturing to deglaze cylinder walls in automotive applications. Brush Research embraced the benefits of a plateau finish and pioneered the concept of plateau honing culminating in the introduction of the Flex-Hone tool in 1972. The Flex-Hone has gained many nicknames over the years and including ball hone, ball style hone, flexihone, dingleberry hone, bead brush, glaze breaker and glaze buster. Flexible honing with the Flex-Hone tool produces an oil holding cross hatch pattern and a true plateau finish free of cut, torn and folded metal. Any type or size of cylinder can benefit from the Flex-Hone®. These abrasive bead style brushes are produced in standard diameters from 4mm to 36 inches. Nine abrasive types are offered including silicon carbide, aluminum oxide, boron carbide and diamond allowing the tool to be tailored to finish any base material. A choice of 11 different grit selections are available for precise control of finish parameters. The elimination of peaks results in rapid ring seating, better oil control, reduced seepage in hydraulic and pneumatic applications and provides better seal performance and longer seal life. Successful applications include firearm chambers, shotgun barrels, musical instruments, combustion chambers, air compressors, pumps, valve bodies, valve guides, brake cylinders, wheel cylinders and the list goes on and on. Flex-Hone® tools are also very effective for deburring cross drilled holes, port radiusing and edge blending. Because of its unique construction, the Flex-Hone is self-centering, self-aligning, and self-compensating for wear so it does not require an elaborate set-up or special training. Deburring can be effectively automated and combined in the machining process to allow a complete cylinder finish in one operation or it can be employed as a secondary operation with equal results.
- Flexible abrasive cylinder hone for surface finishing and cross hole deburring
- Self-centering, self-aligning, self-compensating for wear
- Use by hand or in CNC equipment
- Order by actual bore size, tool produced oversized
- Sizes from 4mm to 36 inches

User questions & answers
Question: | is these 40 grit?? it does not match the number i have PMD |
Answer: | We have your bore as 62.6mm, this hone, the 3" (76mm) is incorrect for your application. Since your bore is a Nikasil application, see our Amazon item ASIN number; B007INTI7S . Just enter this ASIN in the Amazon search bar and it will direct you to the best hone for your application.vAnd yes since this is a finish tool, it will clean up your bore and allow you to create the required crosshatch for proper ring break-in. ..Thank you for the inquiry, PMD Products |
Question: | yes, have used these before but the picture shows 40 grit and list it as what is being sold, but you look at the product information it shows |

User questions & answers
Question: | What material are the stones made from |
Answer: | The flex hone size is supposed to match your bore size and if your bore falls between standard Flex-Hone sizes, the next larger standard Flex-Hone should be selected. Thus the 3" (76mm) is the correct size for a 75mm bore. You should also select the right grit for your application. You can determine this by visiting the Flex-Hone web site at www.brushresearch.com. |
Question: | What stone sets are compatible or where do we buy another set of 220 stones |
Answer: | Probably not. They are a tight fit for the bore size they are listed for. Buy the hone for 70mm and you will have better luck than trying to stuff the 3" hone in a 2.75" bore.http://www.amazon.com/70mm-Flex-Hone-Cylinder-Silicon-Carbide/dp/B002T0B0GC/ref=sr_1_3?m=A221LQEWFFVQAG&s=merchant-items&ie=UTF8&qid=1405513153&sr=1-3 |
