Unitised Metal Pre-Polishing Discs (SAG)
Applications: These discs can save a lot of time when polishing metal by eliminating several stages that might normally requires finer grade abrasive discs. They have fibreglass backing plates and so mount directly to rotary polishers or variable speed grinders. They can also be used on fixed speed angle grinders, but a light touch is required so as not to compromise product life. The grade 5 disc gives a finer finish and can be used from approx 220 grade sanded base to give a bright finish that can be polished further if required using felt discs and polishing compounds. The grade 7 has more aggression and will remove grind marks to leave a smooth, matt surface. Ideal for architectural metalwork, especially stainless steel.
- Unitised (re-pocessed nonwoven) abrasive material
- Grade 5 for finer finishing or grade 7 for more aggression.
- Better to use slower speed for finer results (below 3,000rpm for fine finishing).
- Mounted on backing plates (no backing pad required).
Also Available: Rapid Combi Discs will quickly remove TIG welds on stainless steel, leaving a fine finish.
