Jargon Buster

• Orbital Action: The circular sanding motion used by random orbital and sheet sanders, where the sanding pad moves in small elliptical patterns to create a swirl-free finish without directional scratches.
• Grit Rating: The measure of abrasive particle size on sanding discs, sheets, and belts. Lower numbers (40-80 grit) indicate coarse abrasives for heavy material removal, whilst higher numbers (180-320 grit) represent fine abrasives for smooth finishing work.
• OPM (Orbits Per Minute): The speed measurement for orbital sanders, typically ranging from 10,000 to 26,000 OPM. Higher speeds remove material faster but require more control; variable speed settings allow adjustment for different materials.
• Dust Extraction Rate: The efficiency with which a sander collects sanding dust, usually expressed as a percentage. Professional sanders with integrated dust collection and extraction port connections can capture 90-95% of dust, improving visibility and protecting respiratory health.
• Backing Pad: The base plate or platen that holds the abrasive paper or disc. Can be soft, medium, or hard density depending on whether you need flexibility for contoured surfaces or rigidity for flat sanding.
• Hook-and-Loop/Velcro Fixing: The quick-change attachment system used on modern sanders, allowing rapid replacement of abrasive discs and sheets without adhesives or clamps.

How to Choose the Right Sanders

Selecting the appropriate sander depends on several key factors:

Type of Work: Consider the predominant tasks you'll undertake. Belt sanders excel at aggressive stock removal and stripping large flat surfaces. Random orbital sanders provide swirl-free finishes on curved and flat surfaces. Sheet sanders (also called palm or finishing sanders) suit detail work and reaching into corners. Delta sanders with triangular pads access tight angles. Wall sanders on extending poles tackle ceilings and walls without ladders. Specialised tools like bobbin sanders smooth curved edges, whilst disc sanders handle edge finishing.

Power Source: Mains-powered 230V corded sanders deliver consistent power for extended use, ideal for workshop environments and sites with reliable electricity. Cordless sanders powered by lithium-ion batteries (typically 18V platforms) offer excellent mobility for site work, especially when matching your existing battery system from manufacturers like Makita, DeWalt, or Milwaukee. Consider runtime requirements and whether you have spare batteries available.

Power Rating and Performance: Corded sanders typically range from 200W for palm sanders to 1200W+ for heavy-duty belt sanders. Higher wattage generally means faster material removal, though motor efficiency varies between brands. Check the OPM rating for orbital sanders and belt speed (measured in metres per second) for belt sanders – faster isn't always better if you're working with delicate materials or require fine control.

Dust Extraction: Professional-grade sanders from brands like Festool and Bosch feature highly efficient dust collection systems that capture over 90% of particles, essential for complying with HSE guidelines on workplace exposure to wood dust (a known carcinogen). Look for integrated dust boxes for occasional use, or extraction ports compatible with workshop vacuum systems for regular work. Models meeting extraction standards significantly improve visibility and reduce cleanup time.

Ergonomics and Vibration: Extended sanding sessions can cause fatigue and health issues. Quality sanders incorporate anti-vibration systems, rubberised grips, and balanced designs. If you're using sanders daily, investing in low-vibration models helps comply with Hand Arm Vibration Syndrome (HAVS) regulations and protects long-term health. Consider weight, grip positions, and whether the design suits your hand size and working style.

Budget and Quality Tiers: Entry-level sanders (£30-£80) from brands like Einhell and Black & Decker suit occasional DIY use. Mid-range options (£80-£200) from DeWalt, Bosch, and Makita offer better durability, performance, and dust extraction for regular tradespeople. Professional-grade tools (£200-£600+) from Festool, Fein, and Milwaukee justify their cost through superior build quality, advanced features, innovative dust extraction, and extended warranties for daily commercial use.

Popular Accessories

• Abrasive Consumables: Sanding sheets, discs, and belts in various grit ratings from leading manufacturers like Bosch, Festool, and Mirka. Stock a range from coarse (40-60 grit) through medium (80-120 grit) to fine (180-320 grit) for different finishing stages.
• Dust Extraction Systems: Workshop vacuums and dust extractors with HEPA filtration from brands like Festool, Bosch, and DeWalt that connect to sander extraction ports, essential for maintaining clean, safe working environments.

Safety Information

Safe sanding practices protect your health and prevent accidents:

Respiratory Protection: Wood dust, particularly from hardwoods and MDF, is classified as a carcinogen under COSHH regulations. Always use effective dust extraction systems and wear appropriate respiratory protection (minimum FFP2 masks, FFP3 for sustained exposure) even with extraction. The HSE sets Workplace Exposure Limits for wood dust that employers must observe.

Eye Protection: Wear safety glasses or goggles conforming to EN 166 standards to prevent dust and debris entering eyes, even when using tools with dust collection systems.

Hearing Protection: Many sanders produce noise levels requiring hearing protection under the Control of Noise at Work Regulations 2005. Prolonged exposure above 85dB necessitates ear defenders or plugs.

Vibration Awareness: Hand Arm Vibration Syndrome (HAVS) is a serious concern for those using power tools regularly. Know your sander's vibration rating (measured in m/s²), take regular breaks, maintain tools properly, and keep hands warm. Employers must assess and manage vibration exposure under the Control of Vibration at Work Regulations 2005.

Electrical Safety: Ensure sanders are PAT tested regularly if used commercially. Check cables and plugs before use. Use RCD protection (30mA trip) when working on sites or with extension leads. Never use damaged electrical equipment.

Secure Workpieces: Always clamp or secure items being sanded to prevent movement. Never hold small pieces by hand whilst sanding. Ensure adequate lighting and maintain clear, organised work areas.

Material Awareness: Some materials release toxic dust when sanded (lead paint, treated timber, certain plastics). Identify materials before sanding and take appropriate precautions including enhanced extraction and respiratory protection.

Frequently Asked Questions

What's the difference between orbital and random orbital sanders?

Standard orbital sanders (sheet sanders) move in a fixed circular pattern and are excellent for fine finishing with minimal material removal. Random orbital sanders combine rotation with an offset orbital motion, providing faster stock removal whilst still achieving swirl-free finishes. Random orbital sanders are more versatile for general purpose work, whilst sheet sanders excel at detail finishing and edge work.

Can I use a sander to remove paint from walls?

Yes, wall sanders with extending poles and dust extraction are specifically designed for this task, allowing you to sand walls and ceilings efficiently without ladders. For smaller areas, palm sanders or sheet sanders work well. However, test for lead paint in pre-1970s properties – if present, specialist abatement procedures are required rather than dry sanding. Always use proper dust extraction as paint dust presents health hazards.

How do I know which grit sandpaper to use?

Start with coarse grits (40-60) for heavy paint removal or significant levelling work. Progress to medium grits (80-120) for general smoothing and preparing surfaces for finishing. Use fine grits (180-240) for final finishing before painting or varnishing, and very fine grits (320+) for between-coat sanding. Always progress gradually through grits – jumping from 60 to 240 grit won't save time as coarse scratches will remain visible through finishes.

Are cordless sanders powerful enough for professional use?

Modern cordless sanders from professional ranges by Milwaukee, DeWalt, Makita, and Festool deliver performance comparable to corded equivalents for most applications. Battery technology has advanced significantly, with 18V platforms offering ample runtime for typical site work. The mobility benefits often outweigh the slight power difference, particularly for site joiners and installers. Keep spare batteries charged for uninterrupted work, and consider corded models if you're predominantly workshop-based or undertaking prolonged heavy sanding.

Why is dust extraction important on sanders?

Effective dust extraction serves multiple purposes: it dramatically improves visibility of your work surface, extends abrasive life by preventing clogging, reduces cleanup time, and most critically, protects your respiratory health. Wood dust is a known carcinogen, and the HSE strictly regulates workplace exposure. Professional sanders with 90%+ extraction efficiency are investments in your long-term health. Poor dust control also affects others in your working environment and can damage other equipment.
