I need to mill some slots in some 1095, annealed steel. I can use a dremel
to finish up, or file work. The slot (or groove, a long hole) is to be
.25"
x 3 "

Is it possible to chuck some kind of machinist bit in a router to do the
job? The material is .125 thick. My router has variable speed, of course,
and I plant to build a jig if this is possible.

What is the router's minimum speed? I have actually done slots using a
TC burr in steel that was about 1/2" thick, using a bench drill (flame
pants on). But that was slow speed..... say 200 RPM with a 1/2" diam
burr. It worked. I would not make a living out of it! G. This was a
"once a year" job.

I have also free-handed into similar steels, using a hand drill, at up
to 1300 RPM. Takes practice.

I used a round-ended burr, rather than a square ended one, and drilled
ths start hole first. The round ended one is a good "GP" burr that
will not chip as easily.


My other alternative is to just drill some holes, and grind out the
excess,
of course.

Thanks for any help....
