abrasive disc for hardened steel

abrasive disc for hardened steel

(OP)
Hi.

I need some tips for an abrasive disc that is good for cutting steel that has been heat treated(60-65 HRC).
In the workshop we use the same disc as we use for softer steel (25-30 HRC), but when we have a hardened one, the disc breaks after the cutting is made.

Any useful tip would be great. I want to test and then maybe buy some discs.
Thanks.

RE: abrasive disc for hardened steel

You really want a water cooled saw if you are cutting the harder material. You also need to make sure the material being cut is properly constrained. If it moves at all during the cut the disc will break.

In general the harder the material that you are cutting the softer the binder in disc should be. You need for it to break down and expose fresh abrasive faster.
You can also change the type of abrasive, size of the particles, and other such features.
For really hard materials water cooling is nearly a must.

Do you deal directly with either Norton or 3M? Either can help you with this.
