Shank: Morse taper shank
Taper-shank drill bits press fit into a Morse-taper shank usually found on drill presses and lathes. They’re used in heavy-duty and horizontal drilling. The taper provides a strong, slip-resistant grip in heavy, high-torque applications.
High-Speed Steel Taper-Shank Drill Bits
These high-speed steel taper-shank drill bits for metal and plastic absorb more shock and vibration than cobalt and carbide drill bits, making them suitable for use in manual drilling machines and handheld power tools. Regular-spiral flutes are best suited for nonchipping hard materials such as nonferrous metals, cast iron, and structural steel.

Every HSS twist drill has a cutting end and a holding end. The holding end — the shank — determines how the drill connects to the machine, how torque is transmitted, and ultimately what diameter range the drill can cover. In industrial metalworking, two shank systems dominate: the straight (cylindrical) shank and the taper (Morse Taper) shank. Choosing the wrong one does not just mean poor performance — it means the drill physically will not fit your machine.
This guide provides a complete technical comparison for procurement engineers, workshop managers, and distributors who need to stock the right drills for their customers’ machines.
Two Shank Systems for Two Worlds of Drilling
The straight shank and taper shank are not competing designs — they are complementary systems engineered for different machine types, diameter ranges, and production environments.
Straight shank drills (DIN 338, DIN 340, DIN 1897) are held by a 3-jaw chuck or collet. The chuck jaws clamp around the cylindrical shank with radial pressure. This system is universal: any straight shank drill fits any 3-jaw chuck within its capacity range (typically 1–13 mm or 1–16 mm). Straight shank drills are the standard for hand drills, drill presses, and CNC machining centers. 1/4″ Hex Shank Step Drilling Bit 3/16″ – 7/8″ (12 Step Size) for Metal, Stainless Steel, Aluminum
Taper shank drills (DIN 345, DIN 1870) use a Morse Taper (MT) — a precision-ground conical shank that is pressed into a matching taper bore in the machine spindle. There is no chuck. The drill is held by friction between the two tapered surfaces, with a tang at the end that engages a slot for ejection. Taper shank drills are the standard for radial arm drills, lathes, milling machine spindles, and heavy-duty drill presses. M35 COBALT HSS STEP DRILL Bit 1/4″ Hex Shank 1/8″-1/2″ (13 Step Size)
