Sandhu, seeded second, reached the final of the PSA world tour event after beating fourth seeded Mohd Syafiq Kamal of Malaysia 11-7, 7-11, 11-2, 6-11,11-4 in a gruelling 66-minute semifinal.
Harinder now faces the Malaysian unseeded Henry Leung, who has proved the giant killer in this event, having already beaten several seeded players including the top seed Elvinn Keo of Malaysia.
Harinder took time to settle down and even in the first round came back from arrears to get past a qualifier.
