Our customer service team will work with you to either fix or identify a replacement model for your RotoZip tool, and ensure you have a working tool. Unfortunately, RotoZip no longer stocks parts to repair the Rebel or Revolution tools. We do offer a replacement/upgrade program for consumers in the United States or Canada. Replacement tools can vary in price from $60.00 to $80.00 U.S. The replacement is tool for tool. All ZipBits and XBITS are compatible with any RotoZip tool, provided you use the correct size collet. If you have attachments you have used with your older tool and you decide to purchase a new RZ model, please contact us, so that we can work with you on the compatibility of your attachments with the new RotoZip tools. To take advantage of the replacement/upgrade program, please call RotoZip Customer Service at 1-877-768-6947. Our hours are Monday through Friday 8:00AM to 6:00PM, Central Standard Time.
