Below is the list of carbide tipped dead centers that could be made to order. Since these are made against order the delivery could take about 10-12 weeks of time minimum normally. Note that special sized carbide tips have to be made in a minimum quantity of 4-6 pieces. The below listed sizes of carbide tips have been standardized by us and hence can be ordered by you for even 1 piece. Any other special size ordered outside the below list of sizes has to be ordered for a minimum quantity of 4-5 nos.   MT NO.
