Spindle Cup Wire Brush — Drill Mounted, 6mm Shank, 50/75mm

Spindle-mounted wire cup brush on a 6mm shank, for cleaning, deburring and light rust and paint removal in a drill or die grinder. The cup shape faces the wire forward, so it works face-on into flat surfaces, corners and cupped or recessed areas — the general-purpose brush for detail work where a full-size angle grinder brush is too big.

Drill mounted, not an angle grinder brush
This runs on a 6mm shank in a drill or die grinder chuck, rated to a maximum of 4,500 RPM — not a threaded angle grinder brush. If you need a brush for an angle grinder, see our cup brushes and wheel brushes.

Crimped, for general cleaning
Crimped wire is the flexible, general-purpose fill — it cleans, deburrs and prepares without the aggression of a twist-knot brush. For heavier stripping, see our twist-knot spindle brush.

Cup shape
This is the forward-facing cup brush, for working face-on into surfaces and corners. For a flat wheel that works on its edge along lines and flat areas, see our spindle wire wheel brush.
