Bronze Twist Knot Wire Wheel
This 4-inch bronze twist knot wire wheel brush fits angle grinders with a 5/8-11 threaded arbor. It is built for aggressive surface preparation on carbon steel, removing rust, scale and old coatings. The standard twist knot construction delivers high impact cleaning action at speeds up to 20,000 RPM. It is a consumable accessory for metal fabrication and maintenance tasks.
Suited for angle grinder users cleaning carbon steel
This brush serves welders, fabricators and maintenance crews who need fast material removal on ferrous metals. The bronze wire reduces the risk of contaminating stainless steel workpieces. It is not intended for use on non-ferrous metals like aluminium where loading occurs quickly. Buyers needing a finer finish or working on soft materials should choose a crimped wire or nylon abrasive product instead.
5/8-11 threaded arbor compatibility
The brush mounts only on angle grinders equipped with a matching 5/8-11 spindle thread. Verifying the tool arbor size before purchase is essential because the connector type cannot be adapted. Maximum operating speed is rated at 20,000 RPM and must not be exceeded. No other specifications determine fitment for this accessory.

Questions about this item
Will this 5/8-11 threaded arbor fit directly on my angle grinder without an adapter?
Yes, the 5/8-11 threaded hole matches the standard spindle on most angle grinders so it mounts directly.
Can I run this 4 inch bronze twist knot wheel at the 20000 RPM maximum on a grinder rated for lower speeds?
No, you must only use it on a grinder whose no-load speed is 20000 RPM or less to stay within the rated limit.
How can I confirm the 0.02 inch diameter bronze bristles are removing carbon steel cleanly without loading up?
The surface should show a uniform brushed finish and the wheel should not clog or throw excessive wire fragments during use.
