I see little hope in getting what you are looking for...That brand of tools is from Tiawan and based on the cost of a new drill being ~$80 I doubt you are going to find any parts available. You can try asking the manufacturer if they offer any parts and if so where you can get them in the states by using their contact page. I assume though that based on an hourly wage for a maintenance man and the parts cost even if you could get them would far exceed the cost of an $80 drill.
