The BM-SH Series mask protects highly precision-machined surfaces from damage, maintaining bore hole integrity during painting or blasting. With the mask in place the bore hole internal diameter stays free of paint, removing the need for any post-process cleaning. Ease of installation and paint residue elimination make one-time use cost-effective.
