In case the hole pitch has an intersection or the inclination tolerance of the hole is demanding.
By using it before finishing the reamer, the bend of the hole can be modified.

Plus d'informations


When there is tolerance on the hole pitch, or when the allowable margin of error in the hole inclination is very limited, the use of this product before finishing with a reamer allows the hole skew to be corrected.
