Difference between a Chuck , Collet and Tool bit ?

CHUCK

• A chuck is one of the most important devices in lathe machine it is used for holding and rotating a piece of work while performing a lathe operation.

• The workpiece of short length and large diameter of irregular shape which cannot be conveniently mounted between centers are held quickly and rigidly in a chuck.

COLLET

• Collets are the critical connection between the cutting tool and the tool holder (also called a collet chuck).

• Most collets are round, cone-shaped, and slotted.

• Collets encircle the cutting tool shank to evenly distribute holding power around its center bore.

TOOL BIT

• Various cutting tools allow CNC machining centers to produce components with simple and complex geometries. To be more precise, each device serves a unique function.

• CNC machining’s adaptability as a production method directly results from the wide variety of tools available for use, such as drills, bits, and mills
