Response to Anyone do a lot of drill rod forming, hardening and tempering?
Access to a surface grinder and either
a Harig head or a decent indexable
5C collet fixture?
If so, I will make a drawing for you for a
reamer that will do the job for you.
I can save it as a jpeg and post it here or
as a pdf and e-mail either to you.
Since you are removing very little material,
I would make a two flute reamer.With pilot
as you wished.
I do need to know how deep you need
to reach since you are not removing the barrel.
Sorry, read your post again, and saw that you were able
to get what you wanted cut.
What are you having problems with?
the heat treat of the reamer?
Was it a cutting edge relief, rake angle or an edge clearance
I would like to help.
Usually drill rod, ( oil hardening tool steel)
is easy to get hard, and would more than likely not require tempering.
I am sure you must have been able to get the tool hard,
because it sounds like you got the breech end cut.
I am curious if it was not cutting properly,
if it was not just a cutting edge geometry
On the first tries, was the cutting edges breaking down?
I can tell allot by looking at a tool after it is used
as to why it is not cuting properly.
Like I said I would just like to help here.
