Abstract
L'invention concerne une pastille rapportée pour molette de trépan. La pastille 16 comporte un corps destiné à être monté dans un alvéole formé dans la molette 14 du trépan et une tête qui comporte un sommet allongé 18 qui fait un angle aigu A avec l'axe central de la pastille. Les pastilles 16 sont montées dans la rangée intérieure de pastilles d'une molette de trépan de forage dans une orientation telle que leur sommet 18 entre en contact sur toute sa longueur avec les formations terrestres qui sont situées au voisinage du centre du trou de sonde qui est foré, ce qui réduit la charge appliquée aux pastilles et accroît la durée de vie de la molette. L'invention est applicable aux trépans de forage par rotation.
