But he will have to overcome two home players if he is to retain his crown. The 21-year-old Australian fired down 15 aces and lost just six points on serve in a ruthless display that lasted less than an hour.
In Saturday's semi-final he will face Frenchman Jo-Wilfried Tsonga, who thumped compatriot Gilles Simon 6-4, 6-1. And if the third seed wins that, Kyrgios will also face a Frenchman in the final.
"I thought I served and returned really well today," said Kyrgios. "All that matters is that I'm going out there and playing every point hard.
Second seed Tsonga came through a quarter-final between two twice former winners thanks to converting four of seven break points.
The 31-year-old, on a seven-match winning streak, is bidding to win a second tournament in successive weeks after triumphing in Rotterdam last week. Sixth seed Richard Gasquet overcame top seed Gael Monfils in an all-French quarter-final 6-7 (5/7) 6-4 6-2.
He will play another compatriot next in fourth seed Lucas Pouille on Saturday after the latter defeated Russian Daniil Medvedev 4-6, 6-1, 6-4.
