Chamfering question

[mjgillen]

Hi all,

Over the weekend I worked on a bag of 250 pieces of new .223 brass, neck sizing the brass with my Lee Collet die and chamfering the case mouth with my Hornady Chamfer Deburring tool. It appears to me that after about 150 cases the Hornady Chamfer Deburring tool is getting dull and not chamfering the inside of the case mouth as well as it did when I first started. Is this normal? Am I supposed to “sharpen” it every 100 rounds or so (and if so how)? I have another bag of 250 cases to process so I’m a little concerned.

Recommendations?
Opinions?

Thanks,
Michael

No, that's not normal. They should pretty much last forever. If it's dulling, get it replaced.

They should last about 10 life times.
The same tool used to chamfer holes in steel parts in CNC machines will last for months. And they run at much higher RPMs.
I gave my first chamfering tool to my brother after using it about 20 years. He has had it about 25 years now. And I have 25 years worth on the second tool. In the mean time I found 2 more Wilson made tools for about $3 each so I have enough for a while.

Thanks everyone.

I bought two Lyman chamfer neck tools . VLD ID and outside neck, on one handle, I like it much better than the football style tool. The liked the first 1 so much, I bought another one. I find the Hornady pushes a small bur.

Mine is still working great and I got it back around 1974...
Note also: you are only trying to remove burrs and not sharpen the case mouth edge.

Same RCBS tool since maybe 71/72. No clue to how many times it has been used but it's a big number.

I think some of the more modern tools may be made in China. Could be bad steel or poorly hardened. I have boxes of old American made screws my Grandfather bought in the 40s and 50s. I've never seen one break. I've snapped a lot of the newer versions from the local hardware store.

It is hardened steel cutting brass by hand or very slow.

I suspect with that many cases you may have been the one getting dull. Can you spell "monotonous?"

Tool is probably getting a little dirty and you are probably getting a little tired (bored). They always cut slow when this happens. Change tasks and come back after half hour or so. They will usually speed up.
