Din341 Morse Tapers come in eight sizes identified by number between 0 and 7. Din341 Morse Taper drill bits are used in a variety of applications including metalworking. Din341 Morse Tapers are also used in some metal and steel, stainless steel lathes.

Key Features
Manufactured with premium quality HSS Steel Drills are heat treated with advanced heat treatment technology giving it consistent quality Drills are produced on advance CNC machines which deliver accurate and consistent geometry. More number of holes per drill saving cost.
Most all taper shank drill bits have a tang at the base of the shank for holding and removing the bit.The shank of the drill bit tapers towards the cutting edge, providing a secure fit and minimizing the tendency to slip when drilling into hard materials. A taper shank drill (high-speed steel) is a cutting tool that is attached to a drill press, a milling machine, a lathe, etc. and used to drill holes. The base metal, high-speed steel is a material with metal components such as tungsten, molybdenum, and chrome added, and has excellent abrasion resistance and toughness.

Taper Shank — Friction Taper Self-Locking
A taper shank drill has a conical shank ground to a precise Morse Taper profile (approximately 1.5 degrees included angle, varying slightly by MT number). When the taper is pushed into the matching bore of the machine spindle, the large surface area of the taper creates a friction lock that resists both rotation and pullout.

Key features of the taper shank system:

Self-locking: The slight taper angle (roughly 5/8″ per foot for most MT sizes) means the drill wedges tighter as axial force increases. The harder you push, the stronger the grip. HSS DIN341 / ANSI B94.11-1977 Taper Shank Twist Drill Bit
Tang: A flat tab at the end of the taper engages a cross-slot in the spindle bore. The tang prevents rotation only as a safety backup — the primary torque transmission is through the taper friction. The tang also provides a surface for the drift key to eject the drill.
No chuck needed: The taper-to-bore connection is the entire holding mechanism. This eliminates the chuck as a source of runout and removes the maximum diameter limitation of the chuck.
Rigidity: Because the drill shank is in direct contact with the machine spindle bore along its entire taper length, the system is inherently more rigid than a 3-jaw chuck, especially for large diameters.  HSS DIN341 / ANSI B94.11-1977 Taper Shank Twist Drill Bit
