NEO TOOLS punta per calcestruzzo SDS Max 28 x 600 mm S4 Quatro

Professional contractors and serious DIYers tackling reinforced concrete foundations or heavy masonry walls need a drill bit that won't quit. The NEO TOOLS 57-532 SDS Max bit delivers exactly that: a 28 mm diameter, 600 mm overall length, and a quad-cutter carbide head that powers through the toughest aggregate. The S4 Quatro design pairs four tungsten carbide cutting edges with a robust centering tip, so you get fast starts and clean, accurate holes without wandering. The high-grade alloy steel body and optimized quadruple helix flutes pull dust out of the hole quickly, reducing heat and keeping the bit sharp longer. Whether you're anchoring structural steel, running conduit through a foundation, or setting heavy-duty anchors, this bit is built for the job.

Why choose it

The four carbide cutting edges don't just drill—they chew through rebar and hard aggregate that would stop lesser bits. The centering tip prevents walking on rough surfaces, so your holes land exactly where you mark them. The optimized flute geometry clears debris fast, which means less binding, less heat, and a longer service life. This is a high-performance, long-lasting bit that professionals trust for daily use.

Ideal use cases

• Drilling anchor holes in reinforced concrete for structural connections
• Creating through-holes for pipes, conduits, and cables in masonry walls
• Setting heavy-duty anchors in natural stone or brick
• Demolition and renovation work where speed and accuracy matter

Good to know

Always use a rotary hammer with SDS Max chuck and hammer drilling mode. For best results, start at low speed until the bit bites, then increase to full power. The bit's working length of 500 mm allows deep drilling, but avoid excessive pressure—let the tool do the work. The S4 Quatro series is engineered for durability, but proper dust extraction will extend its life even further.
