Greg Agresta Posted April 13, 2019 Share Posted April 13, 2019 I'm going to bite the bullet and get a 2x72 grinder. I don't want to buy one of everything, which grit belts do I need most? Lets say the 3 most needed. Link to comment Share on other sites More sharing options...
AndrewB Posted April 13, 2019 Share Posted April 13, 2019 (edited) https://trugrit.com/ https://www.combatabrasives.com/ Types of belts I'm learning is up to your preference on how well you want your finish to look. From my understanding it's all on a personal preference. Everybody here is going to say something different. So you will probably get different answers on here.

jake cleland Posted April 13, 2019 Share Posted April 13, 2019 I generally us a 36 or 40 grit for rough grinding and breaking down the edge after hardening, a 100 grit for cleaning up the lower grit, blending, getting down to sharpening thickness, and finally a 320 to produce a finish from which you can start hand sanding, and take the edge down to zero...

P Jones Posted April 13, 2019 Share Posted April 13, 2019 People usually go through the lower grit belts the most. Personally I use 80 grit belts for general shaping and profiling, specifically the blaze ceramic belts. For wood I use whatever cheap AO belts I can find, normally from Combat Abrasives mentioned earlier above. The rest for metal (wood you generally use AO) I use the 3M Trizact belts, and I absolutely love them. They stay good for a long time, the ones I got months ago still holding up. Like Andrew said though, everyone seems to have their own preference and even then its always changing. Link to comment Share on other sites More sharing options...
jheinen Posted April 13, 2019 Share Posted April 13, 2019 My process is typically 80g ceramic > 120g ceramic > 220g zirc > heat treat > 320g j-flex > 400g j-flex > trizact > scotchbrite. Jeff H.

Will Wilcox Posted April 15, 2019 Share Posted April 15, 2019 Already answered, but in case you want more input... If you only want three types of belts on hand, i would vote for 60-120-320. If a higher polish is desired, hand sanding is the way to go from then on. Link to comment Share on other sites More sharing options...
