Angle Grinders

About Angle Grinders

Angle grinders are versatile power tools essential for cutting, grinding, and finishing work across metal, stone, concrete, and masonry applications. MyToolShed.co.uk stocks a comprehensive range of angle grinders from leading professional brands including Bosch Professional and DeWalt, alongside dependable options from Bosch Home and Garden and Black and Decker for DIY enthusiasts.

Available in both corded 240v and cordless battery-powered models, angle grinders are classified by their disc diameter—typically 115mm, 125mm, 150mm, 180mm, or 230mm. These tools accept a wide variety of accessories including cutting discs, grinding wheels, wire brushes, flap discs, diamond blades, polishing pads, and sanding discs, making them indispensable for professional tradespeople and serious DIYers alike.

Applications

Angle grinders are indispensable tools for numerous trades and industries:

• Metal fabrication and welding – cutting steel, grinding welds, removing rust and paint
• Construction and groundwork – cutting concrete slabs, brick, paving, and asphalt
• Stonemasonry – cutting and shaping stone, marble, granite, and ceramics
• Plumbing and pipefitting – cutting metal pipes and preparing joints
• Tiling – cutting tiles and drilling holes with diamond core bits
• Vehicle maintenance and bodywork – removing rust, polishing, and cutting metal panels
• General maintenance – removing mortar, wire brushing, surface preparation, and woodcarving

Choosing The Right Angle Grinders

Disc size: Smaller 115mm and 125mm grinders are lightweight, highly manoeuvrable, and ideal for general-purpose work. Larger 180mm and 230mm models provide deeper cutting capacity for heavy-duty applications like concrete cutting but are considerably heavier and less easy to control.

Power source: Corded 240v angle grinders deliver consistent power for extended use, perfect for workshop environments. Cordless 18v models from MyToolShed.co.uk offer portability for site work where mains power isn't accessible.

Motor power: Higher wattage (typically 750W-2500W for corded models) provides more cutting and grinding capability, especially important for demanding materials. Brushless motors in cordless grinders offer improved efficiency and longer runtime.

Features: Variable speed control allows adjustment for different materials, whilst anti-vibration handles reduce user fatigue. Paddle switches and dead-man switches enhance safety, and tool-free guard adjustment speeds up accessory changes.

Safety Information

Angle grinders are powerful tools requiring proper safety precautions. Always wear appropriate eye protection—safety goggles or a full face shield—as discs can shatter and abrasive materials become airborne. Hearing protection is essential for prolonged use, whilst heavy-duty gloves protect hands from sharp materials and heat. Ensure the disc guard is correctly positioned and securely fitted before operation. Never remove guards or exceed the maximum rated speed of discs and accessories. Work in well-ventilated areas when cutting materials that produce dust or fumes, and consider respiratory protection when necessary.

Frequently Asked Questions

What's the difference between 115mm and 125mm angle grinders?

The 10mm difference affects cutting depth—125mm grinders cut approximately 10mm deeper than 115mm models. Both sizes are similarly compact and lightweight, but 125mm models typically have slightly more powerful motors and offer greater versatility for general trade work.

Can I use a cutting disc for grinding?

No. Cutting discs and grinding discs are specifically designed for their respective applications and are not interchangeable. Using a cutting disc for grinding can cause it to shatter dangerously. Always select the correct disc type for your intended task.

Do cordless angle grinders have enough power for professional use?

Modern 18v brushless cordless angle grinders from premium brands available at MyToolShed.co.uk deliver performance comparable to corded models for most professional applications. Whilst continuous heavy-duty work may drain batteries quickly, they're ideal for site work and increasingly popular with professional tradespeople.
