What am I doing wrong?

I'm using a tubing cutter to cut 1/2" EMT. Works great, but leaves a
burr on the inside surface of the conduit. So I bought a Greenlee
deburring tool.

But I cant fit it into the conduit to get the burr off! The burr is
of such a size that it narrows down the inner diameter of the conduit
so much that the tool wont fit into the conduit to do its thing.

Is there a different deburring tool to use? Different cutting tool? Is
this just a crappy deburring tool? Is there something wrong with my
cutting technique?

Get new cutting wheels, yours are dull. Or cut & de burr like the other posts.
