Les forets de grande longueur en acier rapide offrent plus de flexibilité et absorbent plus de chocs et de vibrations que les forets allongés en cobalt et en carbure. Ils sont ainsi adaptés à une utilisation dans les perceuses manuelles et les outils électriques portatifs. Ils peuvent laisser une finition rugueuse sur le trou. Ces forets de grande longueur ont des goujures plus longues, une longueur totale plus importante que les forets courts de même taille, et une tige plus longue que celle des forets coniques. Longueur plus importante pour trous profonds ou passage dans des zones peu accessibles.
