The seasoned Shiva Thapa (63.5kg) entered the second round, while tournament-debutant Deepak Bohria (51kg) advanced to the pre-quarters of the AIBA World Boxing Championships after dominating victories in their respective opening bouts here on Tuesday.
Five-time Asian medallist Thapa, competing in his third world championship, produced a fine tactical performance to prevail 5-0 against Kenya's Victor Nyadera.
Asian silver-medallist Bohria was equally dominant against Kyrgyzstan's Azat Usenaliev, also notching up a 5-0 win to enter the round of 16.
Thapa, who won a bronze at the showpiece in 2015, will face Sierra Leone's John Brown on October 30 in the round of 32.
Bohria has a tough one at hand on November 1 as he will be up against Kazakhstan's Saken Bibossinov, an Olympic and world championships bronze-medallist.
Earlier on Monday night, debutant Akash Sangwan (67kg) also sailed into the second round with a comprehensive 5-0 triumph over Turkey's Furkan Adem.
Sangwan, a reigning national champion, will next face Germany's Deniel Krotter, who got a first-round bye. The Indian dominated Adem in a lop-sided contest held late last night.
Another debutant Rohit Mor (57kg) gave India a winning start by outpunching Ecuador's Jean Caicedo 5-0 in a confident opening-round performance this evening. Next up for him is Bosnia and Herzegovina's Alen Rahimic.
