A Sapsons Pneumatic Disc Grinder is an industrial air-powered tool designed for grinding, cutting, polishing, and surface preparation.
A Sapsons Pneumatic Disc Grinder is a high-performance tool that operates using compressed air instead of electricity. Built for durability and precision, it is widely used in metalworking, fabrication, automotive repair, and construction industries.
The grinder features a robust, lightweight body that allows for easy handling and reduced operator fatigue during extended use. Its powerful air motor delivers high rotational speed (RPM), enabling efficient material removal and smooth finishing on various surfaces such as metal, stone, and composites.
Equipped with a standard disc mounting system, the tool supports different types of abrasive discs for grinding, cutting, sanding, or polishing tasks. The ergonomic grip and safety throttle ensure better control and operator safety. Additionally, the pneumatic design makes it suitable for hazardous environments where electric sparks must be avoided.
Key Features :
• Air-powered motor for consistent performance
• High speed for fast grinding and finishing
• Lightweight and ergonomic design
• Compatible with multiple disc types
• Low heat generation compared to electric grinders
• Ideal for continuous industrial use
Common Applications :
• Metal grinding and weld smoothing
• Surface preparation and rust removal
• Cutting metal sheets or components
• Polishing and finishing operations
Exact specifications vary by model (e.g., 4”, 5”, 7” grinders like SAP-701A, SAP-915), but typical technical details are as follows:
General Technical Specifications :
• Power Source: Pneumatic (compressed air)
• Disc Size: 4.5', 5', 7', or 9' (depending on model)
• Free Speed (RPM): ~10, 000 – 18, 000 RPM (model dependent)
• Air Consumption: Approx. 4 – 6 CFM (≈ 400–550 L/min)
• Working Air Pressure: Typically 6–7 bar (90 psi) (standard for pneumatic tools)
• Air Inlet Size: 1/4 inch BSP/NPT
• Hose Size (Recommended): ~10 mm internal diameter
Mechanical Details :
• Spindle Thread: Standard (varies by disc size)
• Body Material: Metal housing (industrial-grade)
• Weight: ~0.5 – 2 kg (depending on size/model)
• Handle Type: Side handle or pistol grip (ergonomic design)
Performance Parameters :
• Output Power: Around 150 – 500 W (light/medium duty models)
• Noise Level: ~80–90 dB
• Vibration Level: < 2.5 m/s² (approx.)
Note :
Sapsons provides multiple models, so exact specs (RPM, weight, disc size) may differ slightly.
In short: it is a lightweight, high-speed, and versatile grinding tool designed for continuous industrial use.
