Rotary hammer
A rotary hammer is a powerful electric tool developed for drilling and chiselling hard materials like concrete, masonry and stone. Its high impact power and rotation enable efficient and precise work on heavy-duty building and renovation tasks. It incorporates a strong motor that generates a chiselling action to break and crush material.
How the rotary hammer works:
Unlike standard drills, the rotary hammer has a pneumatic hammer mechanism that delivers strong blows to the engaged tool. This impact action, combined with the rotation of the drill bit, enables effective drilling into hard materials. If rotation is disabled, it also performs chiselling and demolition tasks using just the hammer action.
Types of rotary hammers:
-
SDS‑Plus rotary hammer: Ideal for light to medium drilling and chiselling in concrete, masonry and stone; SDS‑Plus chuck allows quick tool changes and effective power transfer.
-
SDS‑Max rotary hammer: Suited for heavy drilling and chiselling in hard materials like reinforced concrete and natural stone; SDS‑Max fitting offers higher power and larger bit capacity.
-
Combination hammer: Combines drilling and chiselling functions in one tool; excellent for versatile tasks such as drilling, chiselling and material removal.
Applications:
Rotary hammers are essential in the construction industry for a variety of tasks:
-
Drilling holes in concrete, masonry and stone for anchors, plugs and fixings.
-
Chiselling and removing concrete, plaster and tiles during renovation or demolition.
-
Creating openings for pipes, cables and ventilation ducts through walls or ceilings.
-
Breaking through old foundations or concrete structures during refurbishment.
Tips for choosing the right rotary hammer:
-
Power: Check wattage and impact energy (in joules); more power is needed for heavy tasks and larger drill bits.
-
Features: Look for extras like a chiselling-only mode or variable speed – these enhance versatility.
-
Ergonomics: Consider weight, grip comfort and vibration reduction – important for prolonged or overhead use.
-
Brand and quality: Opt for reputable brands with good warranties and service.
-
Accessories: Ensure compatibility with essential tools such as bits, chisels and depth stops – using quality accessories maximises performance.
