Description
The MILLCOT 115mm Multi-Purpose Cutting & Grinding Diamond Disc is the single-disc solution for the angle grinder that has to do everything. It cuts through porcelain, ceramic and natural stone with the chip-free finish a dedicated tile blade gives, and handles plasterboard, fibre-cement board, common nails and metal fixings that would chew through a standard masonry disc — making it the right pick for renovation work where the substrate changes from one cut to the next.
The diamond-coated rim is engineered for sustained dry cutting on hard, abrasive materials, retaining its profile through the kind of use that wears down cheaper bonded abrasive discs in a single morning. Where a standard cutting disc lasts a handful of cuts on porcelain before glazing over, the MILLCOT diamond rim keeps cutting cleanly through hundreds of metres of mixed-substrate work.
Sized at 115mm (4.5") to fit the most common trade angle grinder spindle, the disc covers everything from quick porcelain trim cuts on the wall to slot-chasing through plasterboard, cutting plastic conduit, severing exposed nail heads in renovation strip-out, and trimming fibre-cement boards on-site. A useful piece of kit for renovators, kitchen fitters, bathroom installers and tradespeople who would rather carry one disc than swap between four.
