AT TAPER SHANK DRILLS

AT taper shank drills—often called Morse taper drill bits—are designed to mount directly into a matching taper socket or spindle, rather than using a straight shank held in a chuck (application dependent). This style is commonly used for larger drill diameters and higher-torque drilling where a secure taper fit helps transmit power and reduce slipping. Taper shank drills are frequently used on drill presses, lathes, and other machines equipped with Morse taper spindles.
