• Dry cutting (or air blow) at a depth of cut up ae to .012 in (allowable max. .020 in) and a pick feed pf from .039 to .020 in is
recommended.
• TZF11 type cutters are not designed to adjust dynamic balance. Therefore, when the tool’s overhang ratio (cutter diameter-to- 9
length) exceeds 6:1, special care should be taken with the revolution speed. (At first, start the machining at 50 % of the speed shown in
the table of the standard cutting conditions, and then gradually increase the speed whilst confirming safety.)
• To produce highly accurate surface finish, use the cutter on a machine with sufficient rigidity.

 Cautionary points in use
• Use the cutter for finish milling of vertical wall surfaces requiring • In addition to Z-feed milling, TZF11 type cutters can be also used TAC Mills
long tool-overhang of L/D > 6. for traverse feed milling. (ap ≤ .020 in)
• Radial cutting edge run-out should be adjusted within .0004 in.
