When you're stripping coatings, leveling uneven surfaces, or removing adhesive residue from concrete floors, this wheel cuts through material that stops carbide and aluminum oxide discs cold.\u003c\/p\u003e\n\n\u003cp\u003eDiamond segments bonded to the steel base provide \u003cstrong\u003econsistent cutting performance across 6 to 8 hours of continuous operation\u003c\/strong\u003e. The 180mm diameter matches standard 7-inch angle grinder specifications, fitting Makita, DeWalt, Bosch, and Milwaukee models with proper guard adjustments. No adapter rings or custom mounting required.\u003c\/p\u003e\n\n\u003cp\u003eEach diamond segment contains \u003cstrong\u003eindustrial-grade synthetic diamonds rated for concrete hardness up to 4,000 PSI\u003c\/strong\u003e. These diamonds maintain their cutting edge through repeated contact with aggregate, rebar, and embedded metal that would dull conventional abrasive wheels within minutes. The segments wear evenly, exposing fresh cutting surface as the wheel works.\u003c\/p\u003e\n\n\u003cp\u003eThe welded steel base handles the lateral stress and vibration that comes with heavy-duty grinding applications. Concrete removal generates significant side loading as you work the wheel across horizontal surfaces. This wheel's construction distributes that stress across the entire base rather than concentrating it at weak points.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cp\u003eTechnical specifications for the 180mm Makinex diamond grinding wheel include \u003cstrong\u003eprecise measurements and compatibility ratings\u003c\/strong\u003e for professional grinding applications.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 180mm (7.08 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor hole:\u003c\/strong\u003e 22.23mm standard angle grinder fitting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSegment height:\u003c\/strong\u003e 12mm diamond cutting surface\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM:\u003c\/strong\u003e 8,600 rotations per minute\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended power:\u003c\/strong\u003e 2,000 to 2,400 watts angle grinder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiamond grit:\u003c\/strong\u003e 25\/30 mesh for aggressive material removal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond type:\u003c\/strong\u003e Medium bond suitable for concrete and masonry\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cp\u003eThe 180mm diamond wheel incorporates \u003cstrong\u003e4 key design elements\u003c\/strong\u003e that separate it from standard grinding wheels and cheaper diamond alternatives.\u003c\/p\u003e\n\n\u003ch3\u003eSegmented Diamond Construction\u003c\/h3\u003e\n\u003cp\u003eEach wheel features \u003cstrong\u003e12 individual diamond segments laser-welded to the steel base\u003c\/strong\u003e. This segmented design allows debris to clear between cuts rather than building up and reducing cutting efficiency. The gaps between segments also provide cooling channels that prevent diamond overheating during extended use.\u003c\/p\u003e\n\n\u003ch3\u003eIndustrial Diamond Grade\u003c\/h3\u003e\n\u003cp\u003eSynthetic diamonds in each segment are \u003cstrong\u003egraded specifically for concrete and masonry applications\u003c\/strong\u003e. The 25\/30 mesh size balances cutting speed with surface finish, removing material quickly without leaving deep gouges that require additional smoothing passes.\u003c\/p\u003e\n\n\u003ch3\u003eMedium Bond Matrix\u003c\/h3\u003e\n\u003cp\u003eThe bond holding diamonds in place wears at \u003cstrong\u003ethe optimal rate for concrete work\u003c\/strong\u003e. Too soft and diamonds fall out prematurely. Too hard and worn diamonds don't release to expose fresh cutting surface. This medium bond formulation matches concrete's abrasive characteristics.\u003c\/p\u003e\n\n\u003ch3\u003eReinforced Steel Base\u003c\/h3\u003e\n\u003cp\u003eThe 2.5mm thick steel base includes \u003cstrong\u003einternal reinforcement ribs that prevent flexing under load\u003c\/strong\u003e. Concrete grinding generates substantial side forces as you guide the wheel across surfaces. Base flexing reduces cutting efficiency and can cause premature segment failure.\u003c\/p\u003e\n\n\u003ch2\u003eBenefits\u003c\/h2\u003e\n\u003cp\u003eUsing the 180mm diamond grinding wheel provides \u003cstrong\u003e3 operational advantages\u003c\/strong\u003e over carbide-tipped wheels and standard abrasive discs for concrete work.\u003c\/p\u003e\n\n\u003ch3\u003eExtended Service Life\u003c\/h3\u003e\n\u003cp\u003eDiamond segments typically provide \u003cstrong\u003e15 to 20 times longer service life than aluminum oxide wheels\u003c\/strong\u003e on concrete surfaces. A single wheel handles what would require multiple conventional discs, reducing downtime for wheel changes and keeping projects moving forward.\u003c\/p\u003e\n\n\u003ch3\u003eConsistent Cutting Rate\u003c\/h3\u003e\n\u003cp\u003eDiamond wheels maintain \u003cstrong\u003enearly constant material removal rates throughout their service life\u003c\/strong\u003e. Abrasive wheels start fast but slow significantly as the cutting medium wears. This wheel cuts at essentially the same rate from first use until the diamonds are completely worn.\u003c\/p\u003e\n\n\u003ch3\u003eReduced Operating Cost\u003c\/h3\u003e\n\u003cp\u003eThe higher initial cost of diamond wheels is \u003cstrong\u003eoffset by their extended service life and faster cutting speeds\u003c\/strong\u003e. Labor savings from reduced wheel changes and faster material removal often exceed the price difference within the first major project.\u003c\/p\u003e\n\n\u003ch2\u003eAdditional Information\u003c\/h2\u003e\n\u003cp\u003eThe 180mm diamond grinding wheel works with \u003cstrong\u003estandard 7-inch angle grinders rated for 2,000 watts or higher\u003c\/strong\u003e. Lower-powered grinders bog down under the load required for effective concrete grinding, reducing cutting efficiency and potentially damaging the grinder motor.\u003c\/p\u003e\n\n\u003cp\u003eProper wheel guards are required when using diamond grinding wheels. The aggressive cutting action generates more debris than standard wheels, making eye and respiratory protection essential. Work in well-ventilated areas or use dust collection systems to manage concrete dust exposure.\u003c\/p\u003e\n\n\u003cp\u003eWater cooling significantly extends wheel life when grinding for extended periods. The spray keeps diamonds from overheating and reduces dust generation. However, wet cutting requires GFCI protection and appropriate electrical safety measures around power tools.\u003c\/p\u003e\n\n\u003cp\u003eStorage in dry conditions prevents rust formation on the steel base. Even surface rust can affect wheel balance and reduce cutting performance. Store wheels flat or hanging vertically to prevent warping.\u003c\/p\u003e\n\n\u003ch2\u003eWarranty Information\u003c\/h2\u003e\n\u003cp\u003eMakinex provides \u003cstrong\u003ea 90-day manufacturer warranty covering defects in materials and workmanship\u003c\/strong\u003e. This warranty covers premature diamond segment loss, base cracking, and manufacturing defects that affect wheel performance.\u003c\/p\u003e\n\n\u003cp\u003eNormal wear of diamond segments through proper use is not covered under warranty. Damage from improper mounting, exceeding maximum RPM ratings, or using the wheel on inappropriate materials voids warranty coverage.\u003c\/p\u003e\n\n\u003cp\u003eWarranty claims require proof of purchase and description of the defect.
