💡 What keeps drill and mill bits from jumping inside a hot CNC machine chuck Getting a solid grip on your cutters is a handy fix for chatter and tear out - Pick the sleeve that matches your shaft diameter down to the ten thousandth - Polish the contacting metal faces until they show zero fresh grease or chips - Torque the locking nut gradually so even pressure presses the taper flat - Test the setup on scrap stock first to confirm tracking stays straight tight
