Engine Cylinder Ball Hone Tool - Silicon Carbide - 240 Grit; 25mm

Our Silicon Carbide (Carborundum) Ball Hones are the perfect choice for engine rebuilding, engine reconditioning and other cylinder honing applications.

This hone is suitable for typical engines.

Ball Hone Tools are designed to:

• remove cylinder glaze
• create a new crosshatch
• hone cylinders to ensure they are ready to accept new pistons/rings.

Specifications

• Material: Silicon Carbide
• Grit: 240
• Diameter: 25mm

Picking the right size and grit

• For Large Bore Sizes - Larger than 90mm+: Pick a Ball Hone ¼" / 3-6mm larger than the measured size of your cylinder bore.
• For Medium Bore Sizes - 60mm to 90mm: Pick a Ball Hone 2-4mm larger than the measured size of your cylinder bore.
• For Small Bore Sizes - Less than 60mm: Pick a Ball Hone 1-3mm larger than the measured size of your cylinder bore.

Both 105mm & 108mm hones are suitable for typical V8 engines with 4" cylinder bores.

240 Grit is suitable for most typical applications / classic / old school engines.

320 Grit is suitable for most modern engine applications where a finer finish is required.

Always pick a hone larger than the bore size - i.e. do not pick a 80mm hone for a 80mm bore, choose 83mm.

Note: Please refer to your engine & ring manufacturer to ensure a perfect pick.

Important Notes (!)

• These tools are intended for professional use and must be used with honing oil / suitable lubricant.
• After honing it is critical to clean the cylinder thoroughly with solvent, soap & water and wipe with ATF to check for any grit that may remain embedded in the freshly honed surface.
