I've made my fair share of bumps too. Have broken a couple of end mills also when turning the handles the wrong way too because I let myself get in too much of a hurry. It happens... 
When cutting large pockets I've learned to take out the bulk of the material with a regular twist drill first. A good sharp drill removes metal much faster than an end mill. And your end mill will have an easier time removing the remaining 'swiss cheese' after the drilling.
