I can not say about all the knives as it is not my machine but I can
guess that the bulk of the knives will be tool steel . I thought
grinding steel with diamond was ok as long as you keep everything cool ?
No planer mill I ever heard of could afford the bulk of their knives to
be carbide . As an example . This one machine has 6 cutter heads with
(guessing as I have not counted ) 14 cutters per head . Thats a lot of
carbide . I would like any info at all as I have never used a diamond
wheel . If they will not do tool steel , well that would be information
well worth knowing . Thanks
