Inserting knife used in keyway of motorcycle chain wheel socket

Inserting knife used in keyway of motorcycle sprocket socket:

The keyway in the socket usually uses integral cutter or insert cutter head with inserting cutter rod, but integral cutter is more rigid than inserting cutter head. As shown by the cutter and its geometric angle used in machining common steel gears, the width of the main cutting edge of the cutter head B should be equal to the width of the keyway. If the slot width is larger, the cutter with narrower keyway can be divided twice. Plugged in.
