Tulisa Contostavlos, Gary Barlow, Louis Walsh and Nicole Scherzinger ditch over a third of the 211 acts that they sent through the audition stages without giving them any further chance to impress.
"We've got 72 hours up here for Boot Camp, it's not long. Anyone at this point we don't feel is going to cut it, we should send them home," says Barlow.
"We've made a good call today and it gives the other two thirds of people who are left a good chance of learning something going forward in this competition."
Before the acts are dropped from the competition, they are treated to a party and a surprise appearance from former X Factor finalists JLS.
Offering advice to this year's acts, JLS star Oritsé Williams says: "This is an opportunity that comes once in a lifetime, so you have to make sure you take it with both hands, you know who wants it the most, and it's who wants it the most that will get it."
Louis Walsh backed the decision to axe the acts, commenting: "I know we are doing the right thing. I know it's tough, but that's show business."
Barlow adds: "It's tough but the thing to focus on now is the ones we have put through, it's their shot this week."
After the cull, the acts are put into groups of three and challenged to compete against each other with a song choice given by the judges.
The X Factor Boot Camp auditions start tonight on ITV1.
