WARRANTY & CUSTOMER SERVICE: GORCHEN provides 30 Days Warranty and Lifetime Product Support. Within this period, if the drill tap bit gets broken after usage or for any reason you are not satisfied with it, please contact us for new replacements or return, we will resolve any possible issue for you. USAGE GUIDENCE: • To avoid bits become overheated or even get burned up due to fast rotary friction, we suggest customers to use cutting fluid to keep bits cold during usage. • Can tap through wood, plastic, stainless steel and soft metal plate like aluminum, copper, tin, brass, etc; can't tap through hard metal like steel cast iron plate, etc. • Soft metal plate's thickness should be less than 5 mm; Stainless steel should be less than 2 mm. • We suggest customers to use these bits with threading machines; if you use a hand drill, please keep it stable, otherwise the hand shaking may affect the results' accuracy or even get the bits snapped.
