EveFlex Twist Bristle Brushes
EVE Twists were designed in Germany for polishing precious and non-precious metals. Think of them as a cross between a bristle brush and an abrasive wheel. Use these light weight wheels with your flexshaft or micromotor on a screw-top mandrel 43.128.
They are super-thin, knife edge, abrasive impregnated discs that can be used by themselves or stacked together. This versatility allows you to polish items of any detail. The thin "fingers" can polish down into crevices and cracks, and their flexibility makes for a smooth, even finishing.
EveFlex Twists are impregnated with silicon carbide in a wide range of grits; from 100 to 8000grit in addition to the fine and medium pumice (and color coded for easy identification). Use the grits individually for specific jobs or in succession from coarse to fine to achieve a beautiful finish. They also come in 3 sizes (5/8", 3/4" and 1" diameters) depending on you needs.
EveFlex Twists also have some very clever design features.
1. The "fingers" are straight NOT curved. They can be used in either direction. Unlike other kinds of discs, you don't have to worry about the direction they spin.
2. You can stagger the discs for more even coverage. When you stack more than one EveFlex Twist on your mini mandrel, you can off set them slightly so that the fingers aren't directly lined up. This will give you a more even finish, something you can't do with bent fingers.
3. EveFlex Twists are saucer-shaped NOT flat. This means one side is flat and one side has a slight taper. When you stack the Twists flat side to flat side, you will be building an abrasive wheel that mimics a knife edge wheel. Great for tight areas. If you stack them tapered side to tapered side, you will be building a wheel that is like a square edge wheel. Perfect for area coverage.
