Product questions and answers
Is this the 14 mm or 18 mm version?
This listing identifies the 18 mm version. The 14 mm tool is a separate size and should not be selected from the similar package appearance.
Does 180 grit specify a finished bore tolerance?
No. Grit describes the abrasive grade, not a guaranteed final diameter, roughness or allowable wear limit.
Can it repair a cylinder that is outside its service limit?
No repair allowance is established. Check the cylinder's measured condition and service limits; a finishing tool does not make an unserviceable component acceptable.
