This small upright brush has anti-static horse hair bristle and a static-neutral hardwood handle. This handy brush style, also known as the keyboard brush, has a 2 x 6 row pattern, with a 1" trim, and a brush face of 1" x 1/2". The 1" trim length makes this brush the softest of the WA12 series we manufacture. Ideal for detail cleaning, such as printed circuit boards and SMT assemblies, or for use as fluid applicators. Also great as a dusting brush that works well for getting into tight areas.
