jason0012 Posted June 30, 2022 Share Posted June 30, 2022 Most blades I have made were from simple carbon steel. I make tools also and have run into issues with H-13. Grinding 4140,5160,6150 I can hog into a forged punch or drift no problem and the ceramic belts I am using ( blaze and shredder) seem to last quite a long time. Throwing in H-13 though I have to throw my weight into it to just scrape the scale off. I like H-13, but grinding it is eating belts. Are there better belts for higher alloy steels? Would zirconia or carbide be better? Quote Link to comment Share on other sites More sharing options...
Frazer Posted June 30, 2022 Share Posted June 30, 2022 I use ceramic belts with H13. If you need to do a lot of grinding then anneal first (as best you can, this is a good practice in any case) and/or use a grinding wheel on an angle grinder. Then you can finish with the belts if necessary. Quote Link to comment Share on other sites More sharing options...
JHCC Posted June 30, 2022 Share Posted June 30, 2022 The good news is that, since it's an air-hardening steel, you're not likely to ruin the temper through aggressive grinding. Quote Link to comment Share on other sites More sharing options...
