Knurled black aluminum alloy handwheel, 40mm OD, 7mm bore adjustment handle, turning handles for milling machine, drill press, hand-cranked lathe

Handwheels made of black anodized aluminum alloy; the handles are robust and resistant to wear and corrosion, thus extending their service life. * Precision CNC machining ensures precise dimensions and allows for increased torque on the knurled handles. * The chamfered inner hole arc is more suitable for installing shaft holes. * The handles are robust, resistant to wear and corrosion, thus extending their service life. * These handwheels are suitable for lathes, milling machines, drills, slide platforms, stepper motor fine-tuning wheels, and industrial valves.
