Questions & Answers for Milwaukee 4079 (SER 738B)

Is the Milwaukee spindle sleeve # 45-22-0050 still available or is it is on back order because it has been discontinued. Thanks
Kenneth asked on 2022-05-03
Hello Kenneth, Thank you for the question. Milwaukee currently has the part on a factory back order. They are not able to provide a date at this time. For more specialized assistance or to speak with someone about this, we would suggest calling the manufacturer of the appliance directly. We hope this helps!
