Instructions for slot milling into the solid
Because of the design of the end milling cutter and the special geometry of the insert,
this tool is particularly suitable for producing feather key slots to DIN 138 and DIN 6885.
For this purpose the tools are arranged with an allowance below the nominal diameter.
The angles of entry given in the table are maximum values and should not be exceeded.
