diamond parting tools

Dec 31, 2006 7 Replies

I got a moderately prices diamond parting tool from Penn State Industries. Up until now I have never tried to sharpen it but rather rub both edges on sandpaper lying flat on a workbench. When I hear diamond I think of something harder than a grinding wheel. Does anyone know how they make diamond parting tools (micro diamonds in the steel I assume) and if how they are made makes any difference on sharpening them? Thanks and Happy New Year



A "Diamond" parting tool refers to the cross sectional shape of the tool not the material from which it is made. See:

The "diamond" in the name refers to the shape of the tool shaft, not the inclusion of any actual diamond material. A diamond parting tool has sides that are relieved, resulting in a roughly diamond-shaped cross-section. The advantages of such a tool are that only the side "points" of the diamond contact the sides of the cut, making it much safer and easier to part deeply. They are more expensive because of the extra machining operations that go into them.

When you sharpen it (with exactly the same equipment that you sharpen all of your tools), make sure that the point formed by the bevels on the face meet at the side points, the thickest part, of the cross section.

When I play solitair with a real deck (not on the computer), the *diamond* cards are much *harder* to deal.

L. L. asserted, "the diamond cards are much 'harder' to deal'.

..but they trump those from the deck when honing skew chisels. Does Leo ever cheat Lichtman at solitaire? No! Never! :)

Look for World Championship Solitaire on your cable tv schedule. If there isn't one yet, there will be. I found a Championship Darts show while channel surfing. Can Championship Solitaire be far behind?

Thanks for the information and double meanings. So there are diamond dressing stones, diamond sharpening sets, diamond parting tools and Bedans to contend with if you do woodturning as a hobby :)
