Abstract

Dans le bâtiment on doit percer parfois des trous perpendiculaires aux murs pour la pose de gonds par exemple. Il existe dans le commerce des guide-mèches mais ceux-ci ne tiennent pas compte de la présence des pastilles en carbure de tungstène portées par la mèche, ce qui enlève la précision. L'invention consiste à entourer la mèche 2 d'une fourrure 4 avant de la placer dans le guide du commerce 1 on a ainsi le même diametre que celui des pastilles de carbure 3. Des lumières 5 permettent l'évacuation des déchets. Peut être utilisé dans d'autres cas que le bâtiment.
