Kilkenny ended Galway's reign as All-Ireland U21 Hurling champions with a 4-16 to 2-15 semi-final win at Semple Stadium.
The Cats banged in four goals as they powered their way to an emphatic victory and a place in the final against Clare.
John Power, Ger Aylward and Ollie Walsh all grabbed goals in a devastating 11 minute period midway through the first half as Kilkenny took control, on their way to a 3-9 to 0-11 interval lead.
Power added a fourth goal from a penalty two minutes into the second half as Kilkenny tightened their grip on the game.
Davy Glennon and Joseph Cooney pulled back Galway goals, the Cats held on to make it to the decider with the help of six points contribution from skipper Kevin Kelly.
In the other semi-final, Clare coasted to a 4-23 to 0-7 victory over Antrim.
The Ulster champions were totally outclassed and never looked like getting anywhere near the level their opponents are operating at.
Clare struck for their first goal in the 19th minute when Cathal McInerney beat James O'Mullan with a firmly struck shot. Conor McGrath slipped in behind the Antrim defence to slip home Clare's second goal in stoppage time, giving them a 2-14 to 0-3 interval lead.
McGrath got in for his second goal six minutes into the second half, and Niall Arthur added Clare's fourth.
Antrim did have a spell, during which they pulled back points through Conor Laverty, Eoin McAlonan and Devlin, but those scores were of little consolation on a painful afternoon for Saffron hurling.
