5-Inch Pneumatic Angle Grinder, 12,000 RPM with Safety Lever Throttle and Speed Governor

Brief Overview

This 5-inch pneumatic angle grinder is engineered for controlled, precision grinding applications where operator safety is paramount. The integrated safety lever throttle and speed governor eliminate the risks of uncontrolled acceleration, making this tool ideal for finishing, polishing, and detailed grinding tasks. Whether you're stocking for a professional shop or building a pneumatic tool lineup, this grinder pairs well with larger-capacity grinding equipment for comprehensive disc-grinding coverage across different job scales.

Key Features

• Safety-First Design: Lever throttle with integrated safety lock prevents accidental acceleration
• Speed Governor: Maintains consistent 12,000 RPM operation across varying air pressure conditions
• M22 Spindle: Standard 7/8" spindle mount accommodates universal 5-inch grinding discs
• Compact & Lightweight: 1.91 kg (4.22 lbs) design reduces operator fatigue during extended use
• Detachable Side Handle: Provides secure grip control; easily repositioned for different grinding angles
• Protective Guard: Full-coverage wheel guard with directional indicators for safe operation
• Low Air Consumption: Only 1.6 L/s (3.3 CFM) requirement minimizes compressor demand

Business Advantages for Resellers

Margin-Friendly Positioning: The safety-governor feature and lever throttle design address liability concerns in professional shops, positioning this as a premium safety tool—not a commodity item. You can justify better margins by emphasizing accident prevention and operator peace-of-mind.

Low Barrier to Entry: At 1.6 L/s air consumption, this tool runs efficiently on standard shop compressors (most shops have 2.5–5 HP compressors with adequate capacity), reducing customer installation friction and expanding your addressable market.

Complementary to Other Discs: The M22 spindle is universal across 5-inch disc systems. Cross-sell grinding discs, cutting discs, and flap wheels without compatibility concerns.

Lightweight for Overhead Work: At under 2 kg, this tool is ideal for ceiling-mounted or overhead applications—a genuine advantage over heavier models that fatigue operators on vertical surfaces.

Ideal Applications

• Weld finishing and smoothing: Low RPM relative to smaller grinders reduces burn risk on delicate welds
• Precision edge chamfering: Speed governor ensures consistent results across different materials
• Paint and rust removal: Compact size and light weight suit spot treatments
• Polishing and buffing: Stable RPM prevents chatter on softer abrasives
• Assembly line work: Safety lever throttle meets strict manufacturing safety protocols

Why Distributors Choose This Model

Safety Compliance: Integrated speed governor and safety lock exceed standard pneumatic tool safety expectations—simplifying your compliance conversations with shop owners.

Reliable Daily Driver: Proven pneumatic reliability with no batteries, no cordless charging infrastructure, minimal maintenance compared to electric alternatives.

Air-Efficient: Minimal compressor load means shops can run multiple tools simultaneously without pressure drop, increasing customer satisfaction and repeat orders.
