Perfectly suited for quick and effective honing of brake cylinders or smaller engines such as those of motorcycles, mopeds, lawnmowers, etc.

With a flexible drive shaft for use in electric or pneumatic drills.

Adjustable working pressure through self-expanding and adjustable honing arms.

The specially shaped guide arms press the honing stones precisely and evenly against the cylinder wall.

Only hone when the stones are fully inside the cylinder; during honing, the stones should make light contact with the wall.

Make light vertical movements while honing to create a crosshatch pattern for better piston lubrication.
- Suitable for cylinder diameters from 22 – 63 mm
- 3 stones: 28.5 x 5 mm
