The industrial diamond hollow drill with deep countersink "Made in Germany" features, in addition to the particularly wear-resistant diamond material combinations, an elaborately crafted geometry of diamond crown and countersink ring with eroded segments, cooling channels, slots and bores.
Particularly in facade construction, but also in interior finishing, the quality requirements for deep countersunk drill holes with simultaneously shortened cycle times per countersunk hole have grown. Bohle has incorporated its extensive know-how from its own glass drilling machine construction and numerous special tools into the product line "Industrial diamond hollow drills with adjustable countersink ring". The countersink ring has a diameter of + 12 mm in relation to the drill diameter.
