The brushes are designed with stainless steel stitching through the handle for durability and to prevent bristle pull-out during heavy use.
They are suitable for various tasks with different bristle materials: Stainless Steel (Crimped and Straight) for parts washing and gentle scrubbing, Brass for gentle cleaning, and Nylon for no-scratch cleaning.
Each brush has .005" diameter bristles, with dimensions set to meet or exceed aircraft industry specifications, ensuring longevity and resistance to solvents and hard scrubbing.
