Abstract
Ulepszone kilof (10a) i uchwyt kilofa do urabiania minerału i tym podobne. Ulepszone wiertło i uchwyt wiertła zwiększają efektywną trwałość narzędzia i uchwytu wiertła przez minimalizowanie przesuwania wiertła w uchwycie wiertła. Ruch wiertła jest minimalizowany przez przednie i tylne powierzchnie nośne, które pozostają korzystnie (pomyślnie) sprzęgnięte z przednimi i tylnymi powierzchniami nośnymi uchwytu wiertła dla obciążeń wywieranych na wiertło, które są skierowane głównie do wewnątrz i głównie do tyłu.
