SMT-8521 Professional 4-Inch (100mm) Angle Grinder – 700W High-Performance Motor | 11,000 RPM 

Take your workshop productivity to the next level with the SMT-8521 Angle Grinder, a high-performance 4-inch (100mm) power tool engineered for elite precision, heavy-duty reliability, and exceptional value. This compact powerhouse refuses to compromise on power, making it the ultimate companion for professional metalworkers, automotive technicians, fabricators, tilers, plumbers, and serious DIY enthusiasts who demand fast, clean results across demanding applications.

At its heart is a strong 700W motor that runs at an impressive 11,000 RPM without any load, allowing for quick material removal, clean cuts, and smooth finishes on tough metals, tiles, masonry, and composites.

Technical Excellence & Specifications

• Engineered Power: 700W industrial-grade motor with premium copper windings for consistent torque, excellent heat dissipation, and sustained performance during extended use.
• High-Speed Velocity: 11,000 RPM (no load) for quick, professional-grade cutting, grinding, and polishing—reducing time spent on secondary finishing tasks.
• Compact Agility: 100 mm (4″) disc size enables effortless maneuvering in tight spaces, such as engine bays, exhaust systems, or confined renovation areas.
• Quick-Change System: M10 spindle thread with a 16 mm disc bore for secure, no-wobble accessory mounting and fast swaps—compatible with a vast array of standard cutting discs, grinding wheels, flap discs, wire brushes, and diamond blades.
• Universal Compatibility: Supports 220–240V/50/60Hz power setups, offering flexibility across various regional grids and job sites.
• Net Weight: Approximately 1.8–2.3 kg (lightweight for its class)—minimizes fatigue while providing stable control.

Why the SMT-8521 is a Professional’s Choice

• Durable Build: Reinforced gearbox housing and high-quality motor components resist overheating, dust ingress, and daily job site abuse—built to last in demanding workshops and field conditions.
• Ergonomic Handling: Slim, low-vibration body with comfortable grip reduces hand and arm fatigue, enabling precise control for detailed work like polishing or edge deburring.
• Precision Control: Small disc size and high RPM deliver finesse for delicate tasks, yet the 700W motor packs enough punch for heavy-duty jobs like rebar cutting or rust removal.
• Versatile & Reliable: Balances power and portability — perfect for pros who need one tool that handles everything from rough grinding to fine finishing.

Versatile Applications

• Metalworking: Welding preparation, deburring, steel/aluminum cutting, and surface smoothing.
• Automotive Tech: Exhaust repairs, rusted bolt cutting, body panel restoration, and chassis prep.
• Masonry & Tiling: Precise ceramic/porcelain tile scoring, stone grinding, and brick work.
• Home Reno & Plumbing: A reliable multi-tool for pipe fitting, metal trimming, DIY renovations, and general fabrication.

Safety Certifications & Compliance

The SMT-8521 meets rigorous international safety and environmental standards for safe, legal use in professional and home environments:

• CE Marking  Fully compliant with EU directives:
  • Low Voltage Directive — Ensures electrical safety, proper insulation, grounding, and protection against electric shock.
  • Electromagnetic Compatibility Directive — Minimizes harmful interference and ensures tool immunity in industrial settings.
• Hand-held grinders, disc-type polishers, and sanders (including angle grinders) are certified to the specific harmonized standard. The certification covers:
  • Mechanical hazards (guard strength, disc burst resistance, spindle security)
  • Protection against kickback, accidental start, and overheating
  • Vibration and noise limits
  • Electrical and thermal safety
  • Clear marking and user instructions: EN IEC 62841-2-3 addresses all significant risks for handheld grinders up to 230 mm capacity (with no-load peripheral speed limits), backed by independent testing and technical documentation.
• RoHS Compliance means that harmful substances like lead, mercury, cadmium, and others are kept below safe levels, which helps protect users and the environment.

These certifications are backed by official statements, tests from accredited labs, and complete technical documents, making sure they meet workplace rules (like the EU Machinery Directive and local safety codes) and facilitate easy international trade.
