## Summary description

SDS‑Max concrete drill bit by GRAPHITE, size 18×400 mm, S4 quattro design. Intended for drilling reinforced concrete, masonry and stone with SDS‑Max rotary hammers. Features four‑edge (quattro) cutting head geometry for improved chip removal and stable drilling, and 400 mm length for deeper holes in construction and installation tasks.

## Long description

GRAPHITE Concrete Drill Bit SDS‑Max 18×400 mm S4 quattro is a purpose-built rotary hammer accessory designed for drilling reinforced concrete, masonry and natural stone. The 18 mm cutting diameter and 400 mm overall length allow deeper holes for anchor installation, through-conduit drilling and other construction tasks when used with SDS‑Max rotary hammers. The S4 quattro head geometry provides four cutting edges for efficient chip removal and stable, straight drilling in demanding materials.
Advantages
The quattro four-edge cutting head reduces jamming and improves dust and chip evacuation, which helps maintain drilling speed and accuracy. Hardened carbide tips on the cutting geometry enhance wear resistance and extend service life when working in abrasive concrete and masonry. The SDS‑Max shank ensures secure coupling and reliable power transfer with compatible rotary hammers, while the 400 mm length supports drilling deeper anchor and cable routes without changing to extension rods.
Suitable for
 Drilling anchor holes in reinforced concrete
 Creating through or blind holes for electrical and plumbing installations
 Work with masonry and natural stone in construction and renovation
 Heavy-duty drilling tasks with SDS‑Max rotary hammers
Key specifications
 Shank type: SDS‑Max compatible
 Cutting diameter: 18 mm
 Overall length: 400 mm
 Head design: quattro (four cutting edges) for improved chip removal
 Tip material: hardened carbide for wear resistance
 Typical applications: reinforced concrete, masonry, natural stone
How to use
Secure the drill bit into the SDS‑Max chuck of a suitable rotary hammer following the tool manufacturer's instructions. Mark the drilling point and, when possible, start at low rotation to position the bit, then apply steady pressure and use hammering action as required for concrete. Withdraw the bit periodically to clear chips and reduce heat buildup. For through-holes, ensure the exit area is supported or protected to avoid spalling.
Usage recommendations
Use appropriate personal protective equipment including eye protection, hearing protection and dust mask. Match the rotary hammer to the bit diameter and material conditions; avoid excessive axial force that can damage the bit or tool. For prolonged drilling or very abrasive materials, replace worn bits to maintain efficiency and hole quality.
