  • Best value so far
Size: 40-240 Grit, 50PK
Very solid belts. For the price, you can't beat the quantity and variety of grits. I have noticed there not as tight on the roller of my Milwaukee m12 band file, but at higher speed they work well enough to still make this a great deal! Perfect size, decent construction.

  • Works on Dewalt band file
Size: 40-240 Grit, 50PK
Have been using these for months now and love them! Seemed to work very well for the DeWalt Tool, which is my application. Definitely buy more whenever it is time!
