Galaxy’s Pencil Brushes provide consistency in magnetic properties. At a test completed at the University of Pennsylvania it was found that our Pencil Brushes had 1/3 less standard deviation than that of our competitors. Galaxy’s construction method also prevents wires from escaping, a common occurrence with soldered and glued brushes. No escaping wires means no “furring” (an expression for when wires escape out of the brush and stick to the magnets of the tools affecting the test results) on the tool.
On larger size tools the brushes will also help to support and center the tool, reducing wear on the urethane and increasing the distance the tool can run.
