Review on POWERTEC 13 Inch HSS Replacement Planer Blades for Ridgid Planer R4330, R4331, TP1300LS and AC20502 - Set of 3 Knives by Patrick Ordonez

After months of heavy use of branded hard blades, I finally installed these blades about 5 weeks ago. Initially they fit and worked well for a few passes on softer woods. Scratched very quickly only on wood, hence all my products had lines. Good for old blades, but more than bad after 3 weeks of use in the hobby shop. After pulling through a piece of maple with a very light pass today, I noticed the scrapes look worse. Made another pass to make sure the two blades broke in half and flew out the back of the machine. I have changed many planer knives and never had this problem. My only explanation might be that the steel used in these blades is VERY low quality. Save money and pay a few bucks more for better quality. $27 isn't worth the blades that last less than 2 months and can't even rotate them 'cause they break.
