Railway drill d36 (1С/424), d22 (1С/459)

Drills with mechanical fastening of replaceable polyhedral carbide plates, shortened, increased rigidity, for rail drilling operations TU2.035.1143-93 Shortened drills of increased rigidity with mechanical fastening of replaceable multifaceted carbide inserts dia. 22, 36 mm are designed for drilling holes up to one diameter deep in alloyed and hardened steel parts, on CNC machines, special machines and automatic lines. A big advantage is the use of drills of increased rigidity when drilling holes in volume-hardened railway rails on portable machines such as STR-1, STR-2, STR-3, RSM-1m, 3023, 3028 both in stationary and in the field, and also on special rail-cutting - drilling machines of the MP6-1515 type
