Cordless Rotary Hammers & Demolition Hammers – Professional Tool Selection

SDS plus vs SDS max systems

The SDS plus system is standard for rotary hammers up to 5 kg, ideal for drilling concrete holes up to 30 mm in diameter. It enables quick tool-free bit changes and efficient impact energy transfer. SDS max systems are reserved for heavy industrial machines that penetrate reinforced concrete at larger dimensions.

Battery voltage and performance

Professional models use 18V or 36V batteries, where higher voltage means stronger impact energy. Models from BOSCH Professional and MAKITA with 18V platforms offer an excellent balance between power and battery runtime. For intensive construction work, 36V systems deliver performance approaching that of corded models.

Impact energy and applications

Impact energy measured in joules (J) directly determines the ability to penetrate hard materials. For standard concrete work, 2-3J is sufficient, while professional models reach 5-8J. Demolition hammers like the VILLAGER Električni čekić VLN 1760 are specialized for demolition and chiseling with impact energy exceeding 10J.

Functions and operating modes

Quality cordless rotary hammers offer three basic modes: drilling only, hammer drilling, and chiseling (hammer only). DEWALT and HIKOKI models often include active electronic vibration control that reduces operator fatigue. Check that the machine has reverse function – essential when a bit gets stuck in rebar.

What to check before buying

Always verify whether the battery and charger are included in the package or sold separately. Brands like METABO and SCHEPPACH use their own battery platforms, meaning one battery can power multiple tools from the same system. Machine weight is critical – over 4 kg becomes tiring for overhead work.

Accessories and maintenance

The quality of SDS plus bits directly affects machine efficiency and lifespan. Invest in a bit set with carbide tips from recognized manufacturers. Regularly clean the bit holder of concrete and dust, and lubricate it with special grease every 20-30 hours of operation. Always keep a spare battery on site to avoid work interruptions.
