Review: Duran bastante - tienen mucha lija lo que los hace un poco esponjosos cuando están nuevos, me gusta porque la presión se aplica uniforme en lo que estoy desbastando y dejan un acabado muy liso mientras tengan suficientes capas de lija, cuando se están acabando ya dejan los cortes más notorios en el metal. Yo compro los de grano 40 Review: Best you can get and VERY affordable. ## Features - Benchmark Abrasives 4.5" x 7/8" T27 flap discs are ideal for surface blending, beveling, grinding, deburring, edge chamfering, finishing, stock removal, etc. - Zirconia flap discs are manufactured using European zirconia cloth.

Type 29 is bevelled. Either could be used to sharpen blades, depending on personal preference.36 or 40 grit is very aggressive for fast stock removal. No need to go any finer than that for mower blades. **Q: Does this have the quick change nut on it?** A: These fit any 4.5" angle grinders with the standard lock nut, but they DON NOT have the X-Lock type "teeth" to interface with an X-Lock/Quick Change type angle grinder ## Customer Reviews ### ⭐⭐⭐⭐⭐ Duran bastante *by I***Z on 20 February 2023* tienen mucha lija lo que los hace un poco esponjosos cuando están nuevos, me gusta porque la presión se aplica uniforme en lo que estoy desbastando y dejan un acabado muy liso mientras tengan suficientes capas de lija, cuando se están acabando ya dejan los cortes más notorios en el metal.
