I have all Freud carbide bits and they just are not lasting long with MDF and are already dull and burning the wood after I've cut out about a dozen holes. Is this normal or are there stronger bits I can use?

i pulled out my dick in class many of times and had it shown. get over it bitch...stupid open legged hairy beavered bitch...

going over rms = smaller box, under rms = bigger box...

Low voltage doesn't blow amps. That's a myth.

A router that does the sub holes makes rounded edges also?

I dont know about the longevity. I know my upcut bit has cut its fair share of holes and still cuts like a hot knife. The good thing here is you have carbide tips...they can be resharpened. Find a local guy that sharpens shit and you can probably get it done fairly cheap.

I'm using a porter cable 892 router, and it's a 1/4" bit and I'm using the 1/4" shank and running around 16-17,000 RPMs.

I know I can get them re-sharpened I'm just seeing if there's anything I can do to extend their life.

Also where it started burning I was forcing it a little and that probably didn't help any..

Are you getting any build up on the bits? Might give them a good cleaning and see if that helps.

How deep are you cutting in a single pass? Might just be taking too much out at once.

Out of all of the Freud bits, I've had the best luck with their 1/4" straight bit with 1/2" shank.

I've sense switched from Freud to CMT's spiral upcut and downcut (depending on the application) and have had better luck all around with their bits. The spiral bits expel the chips better, seem to last longer, and are fairly inexpensive.

Have a question about Second Skin? E-Mail me!

Really depends on the bit, the material and the force.


I would try slowing down not only the speed on the bit, but I would also put very little force on it as you work. Seams to work pretty well for me.

Designing, building, and shipping boxes. Yahoo IM - kingsuv00If the listening level is too loud, please inform the driver, so he can promptly pull over, and let you out.

not many cars can get me to pluggin my ears but this one.......damn. I mean the first minute is ok but that thing just really starts digging deeper and deeper in your earhole till you cant stand it no more. Seems like it does it with relative ease....16 12's on 8 amps.........gotta love it. :)
