Had a first yesterday, reamer broke during chambering.

Rustystud

I was chambering a 6.5/300 Weatherby with a "bore rider reamer", and no the bore rider did not break, a flute broke at the shoulder for the entire length of the flute. There was 35psi of flush running and the lathe was turning 105 RPMS. The feed was light. Examination of the reamer shows what looks like a preexisting crack. The flutes were incredibly thin. It was the Customer's reamer and he sent it back this a.m. Knowing the reamer maker, he will most likely tell the customer to pound sand vs replacing it as a warranty defect.

I think he will replace it without any problem . Especially if he knows you were the person who was using it . Larry
 
That's tough. Had one break before. Maker replaced it no questions, worst part was having to wait for the replacement. On inspection of the reamer (for what little I know of metallurgy) looked as if there was a minute crack where it started.
 
Only one I ever had break showed signs of pre-existing cracks...3 flutes at the shoulder/body juncture fell off the instant they started cutting. Reamer was replaced with no fighting, from what I suspect from how a previous post was worded, the same manufacturer....there are positive stories
 
i had a 30br reamer brake once. i think i was chambering the third barrel i had ever done. im not sure why the flute broke but i would bet it was my fault. ptg replaced the reamer no questions asked. lee
 
I assume the barrel is OK? The shards didn't gouge the chamber in a manner that won't clean up?
 
As for a Barrel burner the customer said he had about 500 rounds through the first barrel. As for the second barrel I quit before any damage was done to the chamber. I also have about .750" to go so it should clean up without any problems.
 
Anyone who chambers a lot of barrels and buys a lot of reamers will eventually have one break. Good reamer makers will admit if the reamer is at fault and help with technique where it is not. WH
 
Had the same thing happen last week with a .284. Called the manufacture and they said no prob, a replacement is on the way.
