Makita 2 Pack - 3 Inch Knotted Wire Cup Brush For Grinders - Heavy-Duty Conditioning For Metal - 3" x 5/8-Inch | 11 UNC | 0.020" Thick Wire

2 Pack Set. Simplify your metal conditioning work with easy-to-use, long-lasting and quick cleaning 3" Makita KNOTTED Wire Cup Brush, designed to work with your 4-1/2" Angle Grinder. Unlike a coated abrasive, however, a wire brush or wheel is designed to condition metal surface area and is NOT a metal removal accessory. Ideally suited for removing heavy corrosion, rust, paint, spatter and scale removal while also cleaning weld edges and deburring metal; great for cleaning castings, structural steel and sheet metal while also roughening for adhesion, finishing for appearance and preparation prior to plating or painting. Holding the brushes at an angle of no more than 5° with light, constant pressure ensures full wire-workpiece contact and maximal wire life. Incorrect angles or excessive pressure makes the wires heat up, become fatigued and prematurely break, while also may show up as bluing of the wires and the "groaning" of the angle grinder from the excessive load. Carbon Steel Brushes should only work on Carbon Steel to avoid cross contamination on particular applications such as Stainless Steel/INOX..
