Cylinder Hone Grit Guide: What You Need to Know Before You Buy
Choosing the right cylinder hone grit makes all the difference when you're trying to get the perfect finish inside an engine, hydraulic cylinder, or brake system.
What Is Cylinder Hone Grit?
Grit is the size of the abrasive particles on the hone. It controls how aggressive the honing process is. Tools like our Bore Hone Brush or CeramiX Bore Hone use abrasive grit sizes to match different applications and finish requirements.
Common Cylinder Hone Grit Sizes
| Grit Size | Finishing Level | Best Applications |
|---|---|---|
| 60 Grit | Coarse | Rough, heavy material removal |
| 120 Grit | Medium-Coarse | Standard for engine cylinders prepping for new rings |
| 180 Grit | Medium | Brake cylinders, softer metals |
| 240 Grit | Fine | Honing cast iron or aluminum |
| 320 Grit+ | Very Fine | Mirror finish, hydraulic sealing surfaces |
How to Pick the Right Grit for Your Job
- Engine Rebuilds: Start rough (60–120) → finish finer (180–240)
- Brake Cylinders: 180–240 grit bore hone
- Hydraulic Systems: 320 grit CeramiX bore hone for sealing surfaces
- Cast Iron Cylinders: 120 or 180 grit bore hone
- Aluminum Cylinders: 240 grit or higher
Pro Tip: If in doubt, start finer. You can always remove more material if needed.
Mistakes to Avoid When Selecting Cylinder Hone Grit
- Going too rough for soft metals (causes scoring)
- Skipping grit steps (creates uneven finish)
- Not cleaning debris between grit changes
- Ignoring manufacturer's grit recommendations

What's the difference between a Bore Hone and a CeramiX Bore Hone?
Our Standard and Heavy Duty Bore Hone Brushes feature abrasive balls mounted on flexible wires, offering good rigidity and aggressive cutting action. They are ideal for creating a consistent crosshatch pattern without removing too much material. A CeramiX Bore Hone has a more brush-like design with abrasive-embedded nylon filaments, creating a more flexible tool that conforms to the cylinder walls.
Can I use a coarse grit bore hone to save time?
Not recommended. You'll risk gouging the cylinder walls instead of smoothing them.
What's the best grit for aluminum engine blocks?
Stick with 240 - 320 grit cylinder hones for aluminum surfaces.
Does grit size affect crosshatch angle?
No - the angle is controlled by drill speed and hone motion, but finer grits produce smoother hatch marks.
