These lovely abrasive discs for the JoolTool in 4” are also known as the 3M™ Scotch-Brite EXL Unitised Medium. These are Anie’s favourite abrasives! They do not grind away or remove your material; instead, they burnish and spread it along the surface.
This kit includes 3 discs, each 4" across - one of each grit:
- 1 x COARSE grade disc: great for very deep scratches and surface imperfections on precious metals. It is also great for removing deep porosity & coarse parting lines in jewellery castings.
- 1 x MEDIUM grade disc: slightly harder and denser than the fine grade, great for achieving flat, crisp finishes on raw castings. It is also great for removing porosity & parting lines in jewellery castings, and achieving smooth finishes on raw castings or metal clay, plastics, composites, and acrylics.
- 1 x FINE grade disc: great for "wiping off" and blending in scratches and scuff marks on precious metals, and achieving smooth finishes on raw castings or metal clay, plastics, composites, and acrylics. Its web-like structure blends the metal and remove scratches from both precious and non-precious metals. In just 2 steps you can clean up a raw casting and then finish with our felt disc and compound to a high mirror polish. Great for cleaning up after soldering.
- 1 x VERY FINE grade disk: the final step for optimum smoothness.
Each disc is 4”, and mounted onto backpads. Note: you need to mount each abrasive onto a backpad before use.
