5-Inch Pneumatic Disc Grinder with Safety Lever Throttle and Spindle Lock

Brief Overview

The SI-2515LA is a lightweight, compact pneumatic disc grinder designed for precision grinding, finishing, and surface preparation work. At just 1.91 kg, it delivers 570W of cutting power at 12,000 RPM while maintaining operator control through a safety-engineered throttle system. The integrated speed governor prevents runaway conditions, making this grinder suitable for shops requiring both efficiency and safety compliance. For operations needing larger cutting diameters, consider pairing with larger 7-inch grinding capacity or upgrading to higher-angle grinding versatility as your shop's demands expand.

Key Features

• 5-inch (125mm) disc capacity – Ideal for grinding, deburring, and light finishing applications
• Speed governor – Maintains consistent 12,000 RPM maximum, preventing tool runaway and ensuring repeatable results
• One-push disc lock button – Eliminates spindle nut fumbling; speeds up disc changes by 50% versus traditional spindle locks
• Spindle lock mechanism – M14×2 thread with integrated locking for secure, tool-free disc installation
• Safety lever throttle with lock – Dual-control design prevents accidental trigger engagement; rear exhaust keeps debris away from operator
• Rear exhaust configuration – Directs airflow away from the work area and operator hands
• Auxiliary side handle – Mounted perpendicular to the disc, providing stable two-hand control and reducing torque reaction injury risk
• Low vibration output – 11.0 m/s² acceleration (unweighted) and 3.6 m/s² (weighted) minimizes hand fatigue during extended use

Business Advantages for Resellers

• Compact footprint, high margin appeal – Lightweight (4.22 lbs) makes this attractive to small shops, mobile mechanics, and contract finishers with limited bench space
• Safety-first design reduces liability exposure – Speed governor, safety throttle lock, and spindle lock address workplace safety audits and insurance requirements
• Efficient air consumption – Only 1.3 L/s (2.8 CFM) demand means compatibility with standard shop compressors; minimal uptime loss from tool-related pressure drops
• Fast turnaround on disc changes – One-push lock system reduces nonproductive time, improving customer throughput perception and repeat business
• Suitable for paired selling – Works well as a complement to larger angle grinding systems for multi-task shop setups; create bundle offers with abrasive disc packs

Why This Tool Matters for Your Customers

Grinding shops and maintenance facilities rely on grinders that balance speed with control. The SI-2515LA's combination of speed governor, safety throttle, and one-push disc lock addresses three pain points: unpredictable tool behavior, slow changeovers, and operator fatigue. The low air demand means even shops with older compressor infrastructure can deploy this tool across multiple work stations without equipment upgrades.

At 85 dBA, it's also one of the quieter disc grinders in its class, reducing hearing protection requirements and shop environment stress.

Stock this tool for efficiency-conscious shops and safety-focused operations. Margin is strong, and resale justifies the inventory investment.
