Product Information
Full details
The Dapetz Twist Knot Wire Cup Brush is an essential tool for metalworkers, fabricators, and DIY enthusiasts who need a heavy-duty solution for aggressive surface preparation. It excels at stripping stubborn rust, thick paint, and scale from metal and stone, though its aggressive nature makes it less suitable for delicate finishes or polished surfaces that require a scratch-free appearance.

FAQs
Can I use this on a 125mm angle grinder?
Yes, as long as your 125mm grinder features a standard M14 thread, this brush will be compatible.
What is the maximum speed I can run this at?
The brush is rated for a maximum of 12,500 RPM. Never exceed this limit for safety reasons.
Does it come with a mounting nut?
No, it features a built-in threaded M14 mount, so no separate nut is required.
Is this safe for wood?
It is not recommended for wood, as the steel wire knots will gouge and severely damage the grain.
Should I wear eye protection?
Yes, always wear safety goggles, gloves, and protective clothing, as wire fragments can occasionally break off during operation.
Troubleshooting
Brush vibrating excessively during use
Ensure the brush is threaded correctly and tightened fully onto the spindle. Check for uneven wire wear.
Wires breaking or flying off
Do not exceed the maximum RPM of 12,500 and ensure you are not applying too much downward pressure.
Brush is stuck on the spindle
Use a standard pin wrench provided with your angle grinder to hold the spindle lock while unscrewing the brush.
Pros and Cons
Pros
- Excellent for heavy-duty rust and paint removal
- High wear resistance for long-term use
- Compatible with standard M14 angle grinder spindles
- Aggressive wire density ensures rapid material clearing
- Sturdy build quality for professional fabrication environments
Cons
- Not suitable for use on soft materials or fine finishing
- Requires an angle grinder with an M14 thread
- Wire shedding can occur if run at excessive pressures
- Can leave deep swirl marks if used incorrectly
Setup, Compatibility & Care
Setup:
- Ensure the angle grinder is disconnected from the power source before installation.
- Align the M14 thread of the cup brush with the spindle of your 115mm angle grinder.
- Screw the brush on firmly; most models will self-tighten during operation.
Compatibility:
This brush is specifically threaded for M14 spindles, which are standard on most European and global 115mm angle grinders. Always check your grinder's manual to ensure it supports a 75mm cup brush.
Care:
- Keep the brush clean of debris after use.
- Store in a dry environment to prevent rusting of the steel wires.
- Inspect the wires before each use; if knots are excessively frayed or loose, replace the brush to maintain safety.
