Brief Description: 3M Deburring wheel second life

When it comes to deburr your aluminum parts, the 3M deburring wheel is without no contest the best in its class. It will smooth out the edges without "churning" into the parts. Be careful though because if you abuse, it will heat up and become aggressive. Despite all its qualities, I notice that grooves develop rapidly as you use it. And this is not necessarily desirable. Considering the very high price tag of this tool ($80), I was reluctant at the idea of replacing it despite being damaged only because of those grooves. Having nothing to lose, I’ve decided to test out couple of ideas I was playing with. To my surprise, the sharpening stone (pick one for sharpening an axe or a big knife) I was having in my toolbox for years turned out to be the answer to what I was looking for. It basically flattens the wheel almost like it was new. Only a tad smaller. !! Nevertheless, it worked! The procedure is quite simple; start the bench grinder and push the stone with moderate pressure against it as it spins. The stone will gradually wear out the wheel and you will see the groove disappear like magic. Mine was severely grooved out but the result is simply fantastic. PRECAUTION: Wear a safety mask as it will generate airborne abrasive particules. !!!
