Well, this was fun. I checked out MLCS for the bit I wanted, and being pretty new at this, I was confused at the information being presented on their website.

What I was looking for was a 45 degree chamfer bit that would cut my 3/4" MDF at an angle, and from the chart above, I couldn't determine the depth of the cut, so I figured I'd click the help button and ask for support. Well, the E-Mail trail was a pretty enjoyable read, so I figured I'd post it here.
Hi,
I'm looking at part #5376, which is a chamfer bit which says it is a 1" cutting length. What I'm not certain of, is the 'depth' of the cut. Will this cut a 45 degree chamfer in a piece of stock which is 3/4" deep? (Or, is the 1" cutting length the length of the blade itself?) If I'm incorrect, and this is not the correct part for my application, do you have a 45 degree chamfer bit which will cut a bevel in a 3/4" piece of stock?
Thank you!
Rick
There. I had asked my question in a clear, concise manner. Surely, I was going to get a "sure, please order part number so-and-so, and it will do the trick!" response. Right? Umm, no. Not at all.
Dear Mr. Elphinstone,
Thank you for your inquiry. The cutting depth using 1" stock would be 5/8". The 1" measurement you refer to is is the actual blade length.

Hmm. That didn't explain much to me at all. I'm still stumped. Oh well, maybe it's me. Let me make it easier on the guy. (After all, when companies actually contact you back, that's a plus.)
Hi REDACTED,
I have attached a picture of what it is I'm attempting to achieve, and wondering if you could point me to a product you carry which could assist. Do you carry a 45 degree chamfer bit that will be able to cut the 3/4" MDF?
Thanks!
Rick
At this point, I attached the following picture. I figured I must be failing at explaining what it was I was looking for and thought for certain that this would solve everything.

It's pretty simple, right?
Dear Mr. Elphinstone,
Since you will be cutting the entire profile the thickness of the stock you will need to use the fence on a router table to control your depth of cut. The bearing on the bit will not have any material to be guided by.

Now, I was getting a bit perturbed. Sure, I've only used a router once or twice, but please. I didn't ask how to do the job - I want to know what tool I should use to do the job! He didn't even answer the question being asked! I calmed myself down, thought about how to word my final E-Mail (because I wasn't giving him another chance at this) and wrote:
Hi REDACTED,
I do know how to make my cut - the information I am looking for is whether or not MLCS carries a chamfer bit that can do the job. The size and shape of the stock to be cut is prohibitive to using a router table, as it will be approximately 60" in length, and will not be a straight edge. Thus, while using the router freehand, I will actually be building a template which will be clamped directly under my stock to be cut, and which will act as a guide for the bearing as it cuts.
Does MLCS carry a 1/4" shank 45 degree chamfer bit that will cut to a depth of at least 3/4"? If so, please let me know what the product number is.
Thanks again.
Rick
You can read the above either calmly, or with a slightly psychotic undertone and heavy breathing. It works pretty well either way.
Dear Mr. Elphinstone,
5376 will do the job provided you add the extra thickness provided by the template.
Sincerely,
REDACTED

FINALLY! He did it! I got my answer, and placed my order. But, not before I sent my last E-Mail.
Hi REDACTED,
Awesome. Thanks so much!
Rick
Phew! All done. Now, to wait and see if everything turns out as I hope it will.
