A friend recommended that I look at the Iscar Self Grip Cutoff tool and
so I went to the www.iscar.com site; they have lots of different types
and styles and so I was wondering if anyone has some advice regarding
some of the better Iscar tools vs. the Aloris ones.

One thing that looks VERY interesting from Iscar are some tools that
have coolant holes built in: e.g. [SGFH-K] Self-Grip blades with
internal coolant holes for parting and grooving; and the [GEHIMR/L-SC
or GEHIR/L-SC] internal machining boring carbide bar with a coolant
hole.

Their site is not very good at explaining what's needed to use the
coolant feature on these tools; e.g. special holder and/or pump.
