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 action but still holds its shape
even with repeated use. Excellent for scrubbing and degreasing
parts in solvent prior to polishing and refinishing.

Brass -
Straight wire for a more gentle action that still gets through
built-up grease, oils and fouling. Nylon - Tough, black
nylon provides no- scratch cleaning of surfaces and recesses.
