Rotary Hammer Drill Bit GRAPHITE SDS Plus 24×800 mm S4 Quatro (57H494)

GRAPHITE SDS Plus rotary hammer drill bit 24×800 mm S4 Quatro is designed for drilling through concrete and masonry in construction, installation and renovation tasks. The 24 mm cutting diameter and 800 mm overall length provide the reach and hole size needed for deep anchoring, through-holes and duct passages. The SDS Plus shank ensures compatibility with standard SDS Plus rotary hammers and enables secure, quick tool changes on site.

Advantages

The S4 Quatro cutting geometry optimizes chip evacuation and reduces clogging during deep drilling, increasing drilling speed and maintaining stable runout. Hardened carbide tip material maintains sharpness under high impact and abrasive conditions, while a reinforced flute profile improves debris transport along the full length of the bit. The SDS Plus connection provides reliable torque transfer and straightforward insertion and removal in compatible rotary hammers.

Suitable for

• Drilling through concrete walls and floors for anchors and through-services
• Creating deep holes for fixing bolts and dowels
• Installation work in renovation and construction sites requiring long-reach drilling
• Routing channels for pipes and cables through masonry

Key specifications

• Cutting diameter: 24 mm
• Total length: 800 mm
• Shank type: SDS Plus
• Tip: multi-fluted carbide S4 Quatro geometry for improved chip removal
• Intended materials: concrete, reinforced concrete and masonry

How to use

Install the drill bit by inserting the SDS Plus shank into the rotary hammer's chuck until it locks. Use hammer drilling mode and select an appropriate rotational speed and impact energy for 24 mm drilling in concrete. Apply steady axial pressure without forcing the bit; allow the tool's percussion action to advance the hole. Withdraw the bit regularly during deep drilling to clear accumulated dust and chips and to avoid overheating. After use, retract the bit and clean the flutes before storage.

Usage recommendations

Wear appropriate personal protective equipment: safety glasses, dust mask and hearing protection. For reinforced concrete, pilot the hole if necessary and use progressive advancement to extend the service life of the carbide tip. Use dust extraction or a vacuum when drilling indoors to maintain a clean and safe work area.
