Hello community

Who has experience how reground tools differ from each other if they are ground a) by manufacturer or b) by grinding service?

Are there differences, especially in lifetime?

Yes, there’re differences for sure. The lifetime is not as in case of a new tool.
Grinding by the manufacture is the best (certainly it’s more expensive).

You should try it once with two identical tools to see the difference.

It depends… I’ve also experienced cases when reground tools had held longer as new ones. And the regrinding wasn’t by the manufacturer. The company grinds also for some biggest firms in commission processing. The same tool ground by another firm held less than 1/3 of the original period.

It always depends of how much you’re going to pay. We spend a couple of euro more and receive then reground and recoated tools that hold really well. Sometimes also better as the original grinding.

Try that out.

I believe regrinding by the manufacturer is always the best solution. I, for example, have had the following experience with Pokolm-Voha. They usually regrind tools at the similar machines as during manufacturing. This way tools always get original coating.
It costs more and takes more time. But you have then almost a new tool.
