The UNRVLD Mini Ball Hone Kit gives you the most useful small-bore sizes in one workshop-ready set.
Containing 8, 10, 12, 14, 16, 18 and 20 mm 320-grit silicon-carbide ball hones, this kit is ideal for small hydraulic cylinders, master cylinders, slave cylinders, calipers and other small-bore repair work where a controlled surface refresh is required.
The flexible ball-hone design follows the bore and helps remove light glazing while producing an even crosshatch finish. Each hone is 300 mm overall length for easy drill use and reach.
Includes:
- 8 mm, 10 mm, 12 mm and 14 mm 320-grit ball hones
- 16 mm, 18 mm and 20 mm 320-grit ball hones
- 300 mm overall length
- Silicon-carbide abrasive
Ball hones are intended for light deglazing and surface refreshing only. They are not a substitute for precision boring and honing equipment. Always measure the bore, follow the piston-ring manufacturer’s finish requirements, use suitable honing lubricant, and thoroughly clean the bore before assembly.
