try cutting slower and less depth per pass. and yes if you can accept 1/2" shanks on your router they will last longer.

im cutting the whole /75 at the same time...so your saying do half of that...then go over and do the other half?

Do it in as many passes as possible. I usually do 3/8 passes. 1/4s wont hurt though.

I do 3/4" in 1/3 or even 1/4 passes when using a 1/4 shaft bit. dont forget MDF is pretty dense when it comes to cutting thats why it wont jigsaw as fast as say plywood or MDF

got lucky, and you will still break bits, I go through a bit every 12 or so rings even with 1/4 passes on them, unfortunetly

does the cutting width have anything to do with the quality? and length?

I would imagine the skinnier and or longer the weaker the piece becomes.

Rule of thumb that the editor in cheif for "American Router" magazine gave me...

He told me never to cut deeper (on a single pass) than 1/2 the cutting diameter. So if it had a cutting diameter of 1/2", dont cut deeper than 1/4" on a single pass. Not to mention, what destroys router bits, with respect to MDF wood, is the glue that holds them together.

I can't believe you cut the entire 3/4" at one shot, had to be a b!tch. Take 3-4 passes and move the router slowly each time...
