Re: [CAD_CAM_EDM_DRO] drill rod quality

Try asking for silver steel. Here in the UK you will just get a blank look
if you ask for drill rod.

Drill rod/silver steel is precision ground and quite hard while the 304 is
not ground and a lot softer.

304 stainless steel rod will work but it is less accurately manufacured so
it is best to buy more than you need and select the best bits. It will also
probably wear faster but as it is fairly cheap you can afford to replace it
after a couple of years if it starts wearing.

hi experts,

i am about to make the first step to build my egraver/mill, and as i
have _no_ background in machining or mech. eng. i would ask some
dummy questions a few times.

it was hard to find where to but the "drill rods" for the guides,
finally i have found a company, that sells in small quantities, and
is willing to cut it to pieces for me.

this is the string they gave me about the material the rod is made
from:

1.4301
X5CrNi1810 (másutt: V2A)
304 <- they told me this is the US name/code for it.
KO 33

could someone tell me, if this rod will do with bronze bearings for
my first machine?

it is some kind of stainless steel, also called austenit (or contains
austenit)

sorry for the very beginner question.
