Multi-Profile Knives and Heads

      Shop owner gets advice on finding appropriate cutter heads for a set of nice knives (manufacturer unknown). Included are some set-up tips. July 13, 2005

Question
At an auction, I recently acquired a large batch of two piece carbide (with separate steel backer plates of countless profiles) to make doors and moldings. These are quality cutters and I am unable to find the name of them. I would like to find the manufacturer so I can purchase the cutter head to use the bits in my operation. They are in boxes of 5 with matching profile backer plates with numbers, but no manufacturer. I was wondering if anyone had any suggestion on how I can find out who makes the cutter head to use these bits with? Any help is appreciated.

From Dave Rankin, forum technical advisor:
I suggest that you take a close up picture of the cutters, and post it here. Many manufacturers do not put their name on the tools. It is also very possible that you can purchase the backing plates and inserts aftermarket from many distributors on the woodweb.



From contributor C:
It sounds like you have some type of multi-profile type knives. If that is the case, you can purchase a Multi-Profile head that is more than likely available from many tooling distributors. There are different widths of multi-profile heads available.

From contributor J:
With what we are doing with similar profiles, I've seen the advantages in set up time, finish quality, duration of run, and savings from sharpening, which sooner or later cause the need for replacing the HSS corr. back knives.

The initial investment for the ded. head is $475 and the cost of the inserts are $26 each. My basic concern is the hook angle because I run soft maple primarily, then red oak, walnut, and cherry the least. I run it with all with the same profile. Would the same head provide good results on all three species? The concern is the appropriate hook angle to benefit my soft maple finish.



From contributor F:
Contributor J, A 15 degree hook normally works for small shop applications in the four species. If I were designing dedicated heads for the A.M. four wood types, I would use 12 degree, since no other softwoods are involved. This will give you a good finish in all four cutting with the grain. For coping only, I would use 15 degree with face shear.
