Drill bit SDS‑Max GRAPHITE 24 x 1200 mm S4 quatro for concrete

SDS‑Max GRAPHITE 24 x 1200 mm S4 quatro drill bit is designed for rotary hammers and heavy‑duty concrete drilling. With a 24 mm diameter and 1200 mm overall length, this bit enables deep anchoring, through‑holes and core pilot drilling in reinforced concrete, masonry and natural stone. The S4 quatro head geometry improves cutting efficiency and debris removal for steady progress when working with dense building materials.

Advantages

The SDS‑Max shank provides secure engagement with compatible rotary hammers and reduces slippage during high‑torque applications. The 24 mm cutting diameter balances hole size for standard anchor bolts and through‑fixings while the extended 1200 mm length reaches deep embedment points without the need for extensions. The S4 quatro tip optimizes percussive impact transfer and dust evacuation, resulting in cleaner holes and longer tool life under typical construction use.

Suitable for

• Drilling deep anchor and rebar clearance holes in reinforced concrete
• Creating through‑holes for piping and conduit installations
• Heavy‑duty masonry and natural stone drilling for construction projects
• Preparation of mounting points for structural fixings and fastenings

Key specifications

• Shank type: SDS‑Max compatible shank for rotary hammers
• Cutting diameter: 24 mm
• Overall length: 1200 mm
• Tip design: S4 quatro multi‑cut geometry for improved cutting and dust removal
• Intended materials: concrete, reinforced concrete, masonry, natural stone

How to use

Fit the SDS‑Max shank into the rotary hammer according to the tool manufacturer's instructions, ensuring a secure lock before operation. Select the rotary hammer's hammer‑drill mode and use steady, moderate pressure; allow the tool's percussive action to do the work rather than forcing the bit. Withdraw the bit periodically to clear debris and prevent overheating. For through‑holes or very deep anchor holes, use progressive drilling with intermittent retraction to remove dust and chips.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses, hearing protection and dust protection. Match drilling speed and impact settings to material hardness and the rotary hammer's specifications. For prolonged or continuous heavy drilling, allow the bit and tool to cool periodically to maintain performance and safety.
