How to Choose the Right Demolition Hammers

Power Source: Mains-powered 240v models deliver consistent performance for extended periods and suit static site work or where power supply is readily available. Cordless 18V and 54V FlexVolt options offer unmatched flexibility for working across large sites, in properties without power, or where trailing cables present safety hazards. Consider your typical working environment and whether the convenience of cordless operation justifies the higher initial investment and need for spare batteries.

Impact Energy Requirements: Match the tool's power to your typical applications. Light demolition work like tile removal requires 5-15 joules, medium-duty concrete breaking needs 15-30 joules, whilst heavy structural demolition demands 30-70+ joules. Purchasing excessive power increases weight, vibration exposure, and cost, whilst underpowered tools struggle and increase job times significantly.

Fitting System: SDS Max is the professional standard for most demolition hammers, offering excellent compatibility with a wide range of chisels, points, and clay spades from multiple manufacturers. Heavier breakers may use 28mm hexagonal shanks. Verify that suitable accessories are readily available and affordable for your chosen fitting system before purchasing.

Vibration Control: This is critical for professional users who may spend hours operating these tools. Look for models with sophisticated anti-vibration systems, especially if you regularly exceed the HSE's Exposure Action Value of 2.5 m/s². Premium models from Makita, DeWalt, and Bosch incorporate multiple vibration-damping technologies that significantly reduce HAVS risk and operator fatigue.

Weight and Ergonomics: Consider where you'll be using the tool. Lighter models (4-7kg) can be used comfortably on walls and overhead, whilst heavier units (7-15kg) are best suited to floor work. Side or D-handle configurations affect control and comfort, particularly during vertical applications. If possible, handle tools before purchasing to assess whether the grip positions and weight distribution suit your physique and typical applications.

Additional Features: Variable speed control allows gentler work on delicate surfaces, soft-start reduces initial kickback, and electronic overload protection prevents motor damage. Some models offer rotary modes for drilling large holes in masonry, adding versatility. Integrated dust extraction compatibility is increasingly important for COSHH compliance when working with silica-containing materials.

Safety Information

Demolition hammers are powerful tools that present significant safety considerations requiring careful management on UK sites:

Personal Protective Equipment: Always wear appropriate PPE including safety boots with steel toecaps and midsole protection, impact-resistant safety glasses or full face shield, and hearing protection rated to at least SNR 27dB. Respiratory protection (minimum FFP3 standard) is essential when breaking concrete, masonry, or tiles due to harmful silica dust, in accordance with COSHH regulations. Anti-vibration gloves provide additional protection against HAVS.

Vibration Management: Comply with the Control of Vibration at Work Regulations 2005 by monitoring exposure times and staying below the daily exposure limit value of 5 m/s² A(8). Consult tool documentation for specific vibration emissions, implement job rotation where possible, and ensure tools are properly maintained as wear increases vibration levels significantly.

Electrical Safety: Mains-powered tools should be used with 110V transformers on construction sites in accordance with HSE guidance. Ensure all equipment is PAT tested regularly, inspect cables and plugs before each use, and never operate electrical tools in wet conditions. Install and use RCD protection rated at 30mA maximum for additional safety.

Material Hazards: Before breaking any structure, check for concealed cables, pipes, and services using appropriate detection equipment. Be aware that older buildings may contain asbestos-containing materials requiring specialist removal by licensed contractors. Some demolition work may require structural calculations and Building Control notification.

Safe Operation: Maintain firm footing and stable working positions, use both hands to control the tool, and never attempt to force the chisel or use the tool as a lever. Allow the tool's weight and impact energy to perform the work. Take regular breaks to prevent fatigue, which increases accident risk and vibration exposure effects.

Frequently Asked Questions

What's the difference between a demolition hammer and a combi drill with hammer action?
Demolition hammers are dedicated breaking tools delivering impact energy measured in joules (typically 5-70J) without rotation, designed specifically for breaking concrete and masonry. Combi drills with hammer action are primarily drilling tools with a secondary percussion function for masonry drilling, delivering far less impact force. Whilst a combi drill can drill holes in brick, only a demolition hammer has sufficient power for serious demolition work like breaking concrete floors or removing tiles.

Can I use my demolition hammer overhead or on walls?
It depends on the model. Lighter demolition hammers (typically under 7kg) with impact energy below 15 joules can be used on vertical surfaces and overhead for reasonable periods, though this is physically demanding work. Heavier models exceeding 10kg are really only practical for horizontal floor work due to their weight. Always check the manufacturer's guidance and be aware that overhead work significantly increases fatigue and vibration exposure, so take frequent breaks.

How do I know if I'm exceeding safe vibration exposure limits?
Check your tool's documentation for its vibration emission value (typically given in m/s²). The HSE sets an Exposure Action Value of 2.5 m/s² and Exposure Limit Value of 5 m/s² measured as an 8-hour time-weighted average. As a rough guide, a tool emitting 10 m/s² reaches the daily exposure limit after just two hours of continuous use. Many manufacturers provide trigger-time calculators, and apps are available to help monitor exposure. If you regularly use high-vibration tools, consider implementing job rotation and investing in models with superior vibration control systems.

Are cordless demolition hammers powerful enough for professional use?
Modern cordless technology has advanced considerably, with 54V FlexVolt systems from DeWalt and 36V/40V platforms from other manufacturers now delivering impact energy comparable to light-to-medium mains-powered models (15-30 joules). These are genuinely viable for professional trades like electricians, plumbers, and floor fitters tackling typical demolition tasks. However, for sustained heavy-breaking work or demolition contracting, mains-powered models still offer superior continuous performance and remain the professional choice for the most demanding applications.

Do I need any special training or certification to use a demolition hammer?
Whilst no specific UK certification is legally required for operating demolition hammers, employers have duties under the Health and Safety at Work Act to ensure operators are competent and properly trained. Many contractors require tool-specific training and induction for site access. Understanding vibration risks, COSHH compliance for dust control, and safe working practices is essential. If you're self-employed or a serious DIY user, familiarising yourself with HSE guidance on vibration and dust exposure is strongly recommended before undertaking significant demolition work.
