The Mirka Ultimax 6 x 189 in. 150 Grit B-Joint Narrow Belt is an advanced antistatic abrasive belt featuring Mirka’s Selective Coating® Technology. Tiny cavities in the abrasive surface prevent clogging and keep the belt running cool, delivering aggressive performance, excellent edge wear resistance, and reduced material usage per job. Built on an antistatic t-paper / f-paper backing with an aluminum oxide grain, this 150-grit narrow belt is suited to fine finishing and producing a smooth, consistent surface on hardwood, veneer, chipboard, MDF/HDF, melamine, and solid surfaces. It uses a B-joint, an overlapping joint with compensation on the sanding side so the splice adds no thickness and runs smoothly. Each box contains 10 belts.
