Impact energy in joules per blow is the key dimension. Light scaling, brick chasing, and tile removal: 5-15J. General demolition, light concrete breaking, and trenching: 30-60J. Heavy concrete breaking, paving slab removal, and road work: 80J upward. Match impact energy to the worst-case work the tool will see. Higher impact energy comes with higher tool weight and more operator fatigue — for sustained work, heavier-duty breakers with vibration-isolating handles are essential.
Pneumatic breakers are the most powerful and most reliable for heavy work — but require a compressor sized to the breaker's air consumption (typically 25-50 CFM for medium breakers, 80+ CFM for paving breakers). Mains-electric breakers are self-contained, work anywhere with mains power, and cover light-to-medium work — the workshop and small-site default. Battery breakers offer cordless freedom for site-work but with reduced impact energy and limited runtime — best suited to light-to-medium intermittent work.
Common breaker shank fittings: SDS-Plus (smaller rotary hammers, light demolition), SDS-Max (medium-to-heavy demolition), 18mm hex (medium pneumatic and electric breakers), 25mm and 28mm hex shanks (heavy paving breakers). The breaker spec sheet lists the shank type — match replacement chisels to that fitting. Adapter kits exist for some fittings but reduce energy transfer; a matching-fitting chisel is always better than an adapter.
Chisel and point life depends on the material being broken and the operator's technique. For concrete-breaking, expect 5-15 hours of use per chisel before re-grinding or replacement. For softer materials (brick, mortar, tile), chisels last considerably longer. Re-grinding a worn chisel restores the cutting edge — check that the temper of the steel hasn't been damaged by overheating during use. Replacement chisels and points are available across the standard shank fittings.
Returns are accepted within 30 days of purchase, in original packaging, on orders delivered within the United Kingdom. For damaged-on-arrival items, report within 24 hours with photographs to [email protected] — we will typically arrange collection and replacement at no cost to you. For parts that don't fit your machine, the Fit Guarantee covers a hassle-free return at no cost. For buyer's remorse — you've changed your mind or ordered the wrong item, email us first to obtain a Return Merchandise Number; a restocking fee may apply. Refunds are issued to the original payment method once the return is inspected.
Delivery time depends on the product, your destination, and availability — the estimated time for any item appears on the product page, and 'Check where we deliver' confirms coverage for your postcode before you order. Next-day delivery is available on most products; the option appears at checkout when applicable. We deliver across the UK, Europe, the Middle East, and Africa.
