Our finest, small cleaning brushes. Stainless steel stitching laced all the way through the handle keeps the bristles in place and prevents pull-out under even the heaviest use. Made for the aircraft industry to exceed mil specs so you know they'll last in the gun shop too. Handle is 7-ply, no split laminate that stands up to all solvents and hard scrubbing. Available in three bristle materials to suit any job. Stainless Steel (C) - Crimped wire that holds its shape well. Fantastic for parts washing and also an excellent choice for removing welding scale in tight corners (like bolt knob jobs!). Stainless Steel (S) - Straight wire that gives a slightly softer scrubbing act Mfg: Brownells SPECS: All four have: .005" (.127mm) diameter bristles; 3 rows of 7/16" (11.1mm) long bristles set 3/8" (9.6mm) wide, 1-3/8" (3.5cm) long. 7¾" (19.7cm) long overall.
