Choose the Pack That Fits Your Workload 27 PCS Pack A practical choice for home repairs, occasional metal-cutting jobs, automotive work, and smaller DIY projects. 55 PCS Pack Ideal for frequent users, garages, welders, fabricators, maintenance teams, and workshops that need more wheels ready for repeated cutting jobs. Key Features Ultra-Thin 0.04" Design
At approximately 1 mm thick, the ultra-thin cutting profile creates a narrow kerf that removes less material during each pass. This helps improve cutting efficiency, reduce heat buildup, minimize material waste, and support cleaner cut edges with less finishing work.
Premium Abrasive Grain for Consistent Performance
Made with corundum and white aluminum oxide abrasive grain, PRETEC cutting wheels are built for dependable hardness, wear resistance, and stable cutting performance. The abrasive blend helps maintain efficient cutting action across common steel and metalworking applications.
Double Fiberglass Mesh Reinforcement
Double fiberglass mesh reinforcement helps improve wheel strength and stability during high-speed cutting. This reinforced structure supports smoother handling and dependable performance when used correctly with a compatible angle grinder, wheel guard, and appropriate safety equipment.
Fast & Clean Cutting Results
The thin Type 1 wheel design is engineered for controlled metal cutting with reduced excess burr formation. It is well suited for rebar trimming, pipe cutting, sheet metal work, steel tubing, fabrication projects, automotive repair, and general workshop use.
