To order the tool with a pre-set chamfer size, we recommend adding
a calculated over-the-blade diameter (ØD2 = ØD + .032”) as a suffix
to the order number, otherwise a calculated default dimension is used
(ØD2 = .060” + Ød1).
The first tool in each series are STANDARD TOOLS which should be
used when you have a stable set-up and are cutting any material under 28 Rc.
