* Exceptions
The above table does not apply to the following insert codes: SPCH42TR, SPCH42R, SPCH53TR, SPCH53R, SDKN42MT, SDKN42M,
SDKN53MT, SDKN53M, SEKN42MT, SEKN42M, SEKN53MT, and SEKN53M.
Explanation for the above exceptions:
・Although "H" and "K" indicate precision tolerances, the insert peripheral is not ground.
・"M" in this instance represents "Neutral Hand" insert.
・"T" in this instance represents "negative land" edge treatment.
・"R" indicates the feed direction (Right Hand).
