The wheel's double row segments and 35\/40# diamonds deliver quick cutting through mortar, coatings and surface irregularities, while the 4mm steel body and 28 reinforced segments give stability under load. For anyone preparing floors, trimming edges or removing thin coatings the wheel offers clear time savings and durability compared with basic single-row cups.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble row segments:\u003c\/strong\u003e The two rows of diamond segments allow rapid removal of coatings and bulk material for a smoother finish with fewer passes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e35\/40# diamond grit:\u003c\/strong\u003e Coarse diamonds drive aggressive grinding for fast cutting through mortar, concrete and thin set adhesive.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrong steel body:\u003c\/strong\u003e The 4mm thick steel plate provides stability and resists flex when pushing across large surfaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e28 reinforced segments:\u003c\/strong\u003e Multiple 5mm-thick segments increase durability and even wear, extending service life on larger jobs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWet or dry use:\u003c\/strong\u003e The wheel supports both wet and dry grinding methods so it adapts to different site limits and dust control needs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e7\/8\"-5\/8\" arbor fit:\u003c\/strong\u003e The non-threaded design works with both 7\/8\" and 5\/8\" arbors when used with the correct flange, making it compatible with common angle grinders.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis grinding wheel is aimed at tradespeople and experienced DIYers who tackle floor prep, concrete trimming or stone edge bevelling.
