CYLINDRICAL HELICAL DRILLS WITH REDUCED SHANK, SELF-GROUND VERSION

Cylindrical twist drills with reduced shank, SELF rolled finish, are designed for metal drilling operations requiring high precision. The rolling of the drill surface enhances wear resistance, increasing the tool life during continuous use. The reduced shank allows better fitting in specific tool holders, optimising stability during machining. These drills are suitable for applications requiring a balance between robustness and hole accuracy, maintaining consistent quality of the result. The helical geometry ensures effective chip evacuation, helping to keep cutting temperatures low.
