Yes its a good deal. If you need that type 3 Piece Porter Cable Cove Router
Bit Set you do not have much to loose at $14.99 for three pieces set. I
have used the Porter Cable bits and so far they have performed well.
If you have a need for it, the Freud Quadra-Cut Classical Cove & Round Bits
at $19.99 each, in my view is a better buy. I have used Freud router bits
with good results.

The 1/2" shank size is far better. Freud claimed that they are using a
dropped forged casting instead of a machined mandrel to house the carbide
inserts.
Carbide is made with power metal and baked to specific procedures. The
quality is difficult to verify before using it. When working on 24 hours
shift mast production we learned who had the best carbide. Replacing a
carbide insert on a production line is expensive. We soon found out that it
was worth it to paid a little more. But for the hobbyists regular carbide
grade may be good enough. Porter Cable claimed that their sub fabricator in
China is using grade C 4?
As for me when I make raised panel doors I like a better carbide grade and
mandrel.
Thanks for the information.
When asking Tools King they quickly replied
that Porter Cable sub-fabricators in China was using C4.
Lee Valley replied that their router bits were made in China and the grading
was made
as per their specifications? Lee Valley was unable to provide further
information.
I purchased a Lee Valley Shaker raised panel bit and it performs well, so
far.
On sale ($9.95) at Tools King I bought a Porter Cable 1" core bit with a
1/4" shank.
At first I was very doubtful about the 1/4" shank. I used it with pine,
maple and oak and
It performs well. The question is for how long will this bit keep its
precision and last.
Sharpening of carbide bits could be tricky and costly. At time it could be
cheaper to replace the bit with a new one.

I like the idea of using a diamond hone before storing the bit.

I agree, Freuds are great bits and I have a few, but never used PC bits and
wondered about the quality. I am apprehensive about the shank size, but for
that price, as long as they are quality bits, I'll take a chance.
I'd say as long as you kept the bit on pine and maple and oak.
The 'rose' woods will eat it alive - massive amounts of silicon
in the wood. The sand will dull edges.
If you must, have a rough one to mill out small amounts at a time
and a newer one to to the last fine cut. - Use depth of cut for
small cleaner cuts. Work downwards to finally depth.
Keep one for quality work like you tried.

That is a great deal. Too bad they're not 1/2" shank instead of 1/4"
especially for the 1/2 cove bit.

Every time I use a bit I give it a few swipes with a diamond hone before
I put it away. Seems to extend lifespan quite a bit but of course that's
a subjective judgment.

This is a very handy and inexpensive monocrystaline set:

EzeLaps are polycrystalline, and a tiny bit cheaper, but I prefer the
DMTs. (I own both in 600 grit 2x6" plates.)
