Jack Hammers

About Jack Hammers

Jack hammers, also known as demolition hammers or breakers, are high-powered tools engineered to break through concrete, masonry, tarmac, and other hard materials using concentrated impact energy. These essential demolition tools combine brute force with precision chisel action to tackle jobs that would be impossible with standard power tools, from removing old concrete foundations to breaking up patios and creating channels for services. MyToolShed.co.uk stocks a comprehensive range of jack hammers from leading manufacturers including Makita, DeWalt, Bosch Professional, Draper, Einhell, and Sealey, catering to both professional tradespeople and serious DIY enthusiasts.

Our selection includes corded electric models operating on 240v mains power for consistent, all-day performance, alongside advanced cordless options featuring Makita's XGT and DeWalt's FlexVolt battery platforms. These professional-grade demolition breakers feature impact energies ranging from light-duty 15J models to heavy-duty 60J+ variants, with SDS-Hex or 28mm hex connection systems for quick chisel changes. Modern designs incorporate Anti-Vibration Technology (AVT) to reduce operator fatigue and comply with HSE workplace regulations, whilst brushless motors deliver improved efficiency and extended tool life.

Applications

Jack hammers are indispensable tools across numerous trades and applications:

• Demolition Contractors: Breaking down walls, floors, and concrete structures during renovation projects
• Groundworkers: Removing road surfaces, breaking up foundations, and site preparation for civil engineering works
• Builders and General Contractors: Creating openings in masonry, removing floor tiles, and structural alterations
• Landscapers: Demolishing old patios, removing concrete-encased tree roots, and garden remodelling
• Plumbers and Heating Engineers: Chasing channels in concrete floors for pipework and accessing underground services
• Electricians: Creating cable runs through masonry and forming access points for installations
• Property Developers: Major structural alterations and removing obsolete concrete features
• DIY Enthusiasts: Home improvement projects involving concrete removal and garden renovation

Choosing The Right Jack Hammers

Impact Energy: Light-duty models (15-30J) suit occasional DIY use and thinner materials. Mid-range breakers (30-45J) handle most general construction work, whilst heavy-duty professional models (45J+) are essential for reinforced concrete and intensive daily applications.

Power Source: Corded 240v electric models provide consistent power for extended site work with mains access. Cordless options offer excellent portability for remote locations but require battery management and typically cost more initially.

Weight and Handling: Lighter models (under 10kg) reduce fatigue but may lack breaking efficiency. Heavier breakers (10-20kg) deliver superior results on tough materials but demand greater physical strength. Consider the balance between power and manoeuvrability for your specific applications.

Vibration Control: Models with AVT or advanced dampening systems are crucial for regular use. HSE guidelines require vibration exposure monitoring, making anti-vibration technology essential for professional compliance and preventing Hand-Arm Vibration Syndrome (HAVS).

Brand Quality: Professional brands like Makita, DeWalt, and Bosch Professional offer superior durability and wider accessory ranges. Budget options from Draper, Einhell, and Sealey can suit occasional users but may lack longevity for daily site work.

Safety Information

Operating jack hammers requires strict safety precautions. Always wear appropriate PPE including safety goggles or face shield, heavy-duty gloves, steel toe-capped boots, and hearing protection as noise levels frequently exceed 100dB. Hand-Arm Vibration Syndrome is a serious concern—choose models with excellent anti-vibration systems and take regular breaks to stay within HSE exposure limits of 2.5 m/s² over eight hours.

Breaking concrete generates harmful silica dust. Work in well-ventilated areas, use dust extraction where possible, and wear FFP3-rated respiratory protection. COSHH regulations require proper dust control assessment on commercial sites. Always connect corded models through an RCD for electrical safety, and check for buried services before breaking ground surfaces. MyToolShed.co.uk recommends consulting manufacturer guidelines and HSE resources before operation.

Frequently Asked Questions

What's the difference between a jack hammer and a rotary hammer drill?

Jack hammers deliver pure impact energy without rotation, designed specifically for breaking and demolishing materials. Rotary hammer drills combine rotation with impact for drilling precise holes in masonry. Jack hammers are considerably more powerful and purpose-built for destruction rather than creating controlled holes.

Are cordless jack hammers powerful enough for professional use?

Modern cordless demolition hammers using 40v-54v battery platforms from Makita XGT and DeWalt FlexVolt deliver performance comparable to many corded models. They're excellent for sites without mains access and eliminate trailing cable hazards. However, you'll need multiple batteries for all-day operation, and the initial investment is higher than equivalent 240v corded models.

How long can I safely operate a jack hammer before taking a break?

This depends on the tool's vibration level and HSE exposure limits. Most modern jack hammers with good anti-vibration systems allow 1-2 hours of continuous use, but you should consult the manufacturer's vibration figures and HSE guidance. Professional users must monitor exposure times and maintain usage logs to comply with workplace health and safety regulations.
