Item Details

  • Weiler® Dually™ 4 1/2" X 0.02" Root Pass Stringer Bead Knot Wire Wheel Brush with 5/8" - 11 UNC arbor hole utilizes a nut design that features a dual-hex on each side of the wheel which is high enough to insure adequate tool clearance in either mounting position and rotates at 12500 RPM. Carbon steel wire brush comes with 13/16" trim length and the dual-hex nut design also simplifies periodic flipping of the wheel for maximum cleaning action, long life and safer use. Knot wire wheel brush is ideal for use on right angle grinders. It is the choice for the most demanding inter-pass welding applications such as pipeline construction, boiler and pressure vessel fabrication and shipbuilding. It is sold as 5 per pack.
