1. Brown
Abrasive: Aluminium oxide
Cutting power for aluminum castings, hand tools, knives, stainless steel iron products, such as the modification of metal workpieces and grinding, metal cleaning rust, welding point of the clean-up, modification of a variety of castings, cast grinding, the edges to remove the castings excellent results.

2. Gray/ black
Abrasive: Silicon carbide
Cutting power for aluminum castings, hand tools, knives, stainless steel iron products, such as the modification of metal workpieces and grinding, metal cleaning rust, welding point of the clean-up, modification of a variety of castings, cast grinding, the edges to remove the castings excellent results.
3. Red/white
Abrasive: White aluminium oxide
Workpiece for electroplating metal wire drawing processing, drawing fast, the Silk Road clear, effective, no residue, no black. Of zinc alloy, chrome-plated hard texture of the workpiece, such as the very strong performance. For copper wire drawing parts, need to select the soft round of the drawing, so as not to pull the bad parts; Nickel workpieces for wire drawing, the general hardness is usually the drawing round 5P; And chose thicker coating hardness for the drawing round 7P better (mainly for the lock-type). The edge of the drawing tool may be the hardness of sand for the 5P or 7P No. 240 # round the drawing. For aluminum products, recommend the use of pre-plated hardness of sand 7P No. 180 # -320 # for drawing the round.
4. Green
Abrasive: Green silicon carbide
For applications that require precise and meticulous work, grinding does not produce smooth and left because of high-pressure spots, reduce defects, does not change the original weight of the workpiece, for stainless steel, titanium and other materials, such as insulating glass, cutlery, knives, first-class golf can play a very good effect. After grinding parabolic excellent brightness, it is to meet foreign requirements for the product brightness.
