1. CRATEX Rubber Abrasive Wheels

CRATEX grinding wheels are rubber-bonded, premium-quality silicon carbide abrasives of maximum endurance. They are produced in two types of bonds: standard and hard bond. The standard bond has a unique cushioning action, it provides smooth and soft cut without digging into the surface of the workpiece. It is ideal for smoothing and polishing metallic or non-metallic surfaces. It resists smearing or clogging and provides a perfect finish without losing dimensional tolerance and control. Hard-bond wheels have higher cutting power than the standard-bond wheels and are perfect for removing burrs on hard metals, like stainless steel. They can also be used for light metal removal. Hard bond (HB) is not available in kits and minimum quantities are required.

All grinding wheels come in four grits: Coarse (green), Medium (dark brown), fine (reddish brown) and Extra Fine (grey green). The grit depends on the metal and desired finishing action.

CRATEX large straight-edge wheels are perfect for removing rust, heat marks, tarnish, scratches, corrosion and excess solder.

CRATEX small grinding wheels have either a tapered or straight edge. Tapered or shaped wheels are extremely versatile which makes them ideal for fine operations on small and delicate parts. Straight wheels can be mounted on conventional portable motor tools. They are used on operations that require control of metal removal.

 
2. CRATEX MX Abrasives

MX products are made of premium brown aluminum-oxide. They are cotton-backed laminate-bond abrasives are much more aggressive and firmer than CRATEX rubber bond products. The difference between the two abrasives is that MX bond holds abrasive grains until they are won while abrasive grains get pushed back into the rubber material during use and they fall out as the rubber gets worn away.

The unique construction of MX abrasives gives them an amazing ability to grind, deburr and finish in one operation, because they contain characteristics of three types of abrasives: resinoid, vitrified and rubber-bonded. They do an amazing job with edge breaking, cleaning welds and blending machine lines, and can reduce finishing steps by half.

MX abrasives are available in two different bonds - latex and resin. Latex bonds are typically used for light deburring, blending, and finishing and they come in two grades – soft bond (for general purpose) and medium bond (medium-aggressive). Resin-bonded abrasives are used for light to medium stock removal and they also come in two grades – hard bond (aggressive) and extra bond (very aggressive).
