The Stockport slinger was on song from start to finish, clocking up four successive sets to win 5-1.
"I can't believe what has happened this week and I'm looking forward to the next match," O'Shea said.
In the semi-final, the greenkeeper will meet Mervyn King, who beat Ritchie Davies 5-4 in a thriller.
"I'm still buzzing," said a delighted O'Shea afterwards. "I can't believe
I'm through to the semi-finals.
"I've made the final of the World Darts Trophy, but this [tournament] means everything to me."
He set out his stall by taking the first set before the ever-popular Hankey drew level in the second.
But from there on in it was all O'Shea, the 42-year-old clinching the third set with a bull finish, as he did the sixth to seal the win.
Hankey fought hard to take what proved to be the final set to a deciding leg before the man they call Silverback finished in style.
Later on Friday, King and Davies reached 4-4 before King nailed double 16 and then
double two to clinch victory.
Davies, who lost 6-3 to Raymond van Barneveld in last year's final, started quickly and won the first four legs.
But King hit back with two bull finishes to level the
score at 1-1 in sets.
The Ipswich star then edged to 3-1 up at the interval before Davies grabbed a set back.
King again responded to leave him one set from victory before Davies clinched two tight sets to set up the decider.
King was booed by the crowd in his previous game after asking for the length of
the oche to be checked in his first-round match with Rick Hofstra.
But he said: "I am glad to say the boos were few and far between tonight
because they respected me and Ritchie up there.
"We had a few at the start of the match but they soon got involved in the
He added: "Just to be involved in a match like
that was superb, but to win it is tremendous.
"I have got a lot of bottle and I have always had a lot of bottle. Sometimes
it does not work but 90 times out of 100 I will hold my bottle.
"I have known Ritchie for a long time and he is a fantastic player, a nice
bloke. I have got a lot of time and respect for that man."
