3M 787C Ceramic Sanding Disc, 115mm, 25 in pack / 1683860

3M™ Fibre Disc 787C, 115 mm x 22 mm, 120+, Slotted 3M™ 787C Fibre Disc contains a 3M Precision Shaped Grain (PSG) engineered to offer up to twice the cut-rate surpassing other conventional discs in both performance and longevity. A grinding aid is incorporated to keep the disc cool and further prolonging the disc life. It features a fibre backing and a strong resin bond that improves durability and tear resistance. Designed to maximise cutting effectiveness, minimising grinding pressure and operator fatigue.Using the 3M™ 787C outperforms conventional ceramic discs. Designed to be used with a 3M™ backing pad with an angle grinder or sander. This fibre wheel is well-suited to edge chamfering, machining grooves, removing steel welds and more. Unique Construction The unique construction of the 787C is the perfect solution for the most challenging applications. Constructed by a stiff fibre backing and the 3M™ Ceramic Abrasive Grain blend is resin bonded to provide durability and enhanced tear resistance against the toughest applications. The added grinding aid allows for work on heat-sensitive alloys without warping the workpiece. Optimised Cutting Using 3M™ precision-shaped grain technology to offer a higher initial and durability to outlast conventional ceramic fibre discs. The grit wears evenly and with the abrasive staying cooler and sharper, the PSG abrasive lasts significantly longer than conventional ceramic discs. These discs will help to step up production with an improved output on both light and heavy stock removal. Features and Benefits Cuts hard and fast to grind metals like stainless steel and high nickel alloysPremium mineral excels at heavy weight applications3M Precision Shaped Grain yields higher cut ratesGrinding aid minimises grinding temperatures for heat-sensitive alloysReduce costs with long-lasting abrasive - completes more parts than conventional discsDurable and tear resistantCompatible with 3M™ disc pad face plates (sold separately, RS (387-4220) 387-4220 (127 mm), RS (337-3929) 337-3929 (115 mm). Typical Applications The 3M™ 787C heavy-duty fibre discs are great for weld removals, grinding and blending large and small metal areas. This could occur in industries such as farm and construction, automotive, ship and boat building, metal fabrication. FAQs Q. How do I know which fibre disc to use on what substrate?A. The 787C is used for stainless steel and other non-ferrous alloys such as aluminium and titanium, the 782C disc is used for carbon steel (Sold at RS Components).Q. Would you be able to use these discs on wood?A. No, these are not recommended to be used on wood, just the metals.
