Rotary SDS Max Concrete Drill Bit GRAPHITE 16×310 mm S4 quatro

GRAPHITE Rotary SDS Max Concrete Drill Bit 16×310 mm S4 quatro is a specialist masonry drill designed for rotary and hammer drilling in concrete, reinforced concrete and various types of masonry. With a 16 mm diameter and 310 mm overall length, this drill bit is suited for through-drilling and creating anchor holes where a robust, SDS Max-mounted tool connection is required. The S4 quatro design focuses on efficient debris removal and stable drilling in demanding construction environments.

Advantages

The SDS Max shank ensures secure coupling with compatible rotary hammers, reducing slippage and enabling reliable power transfer. The 16 mm cutting diameter offers a balance between hole size and material removal rate for common anchor and through-hole needs. The 310 mm overall length provides reach for deeper penetrations while the tip geometry and flute design improve chip evacuation and reduce binding during drilling. Constructed for use in concrete and reinforced concrete, the bit is suitable for repeated professional applications.

Suitable for

• Drilling anchor holes in concrete and reinforced concrete
• Through-drilling for installations and conduit runs
• Masonry penetration where SDS Max rotary hammers are used
• Construction, renovation and installation tasks requiring durable drill bits

Key specifications

• Diameter: 16 mm
• Overall length: 310 mm
• Shank type: SDS Max
• Intended materials: concrete, reinforced concrete, masonry
• Design series: S4 quatro (optimized flute and tip geometry)

How to use

Mount the drill bit securely in an SDS Max-compatible rotary hammer according to the tool manufacturer's instructions. Select the hammer or rotary mode appropriate for the material and apply steady pressure while allowing the tool to do the work; avoid excessive side loading. Periodically withdraw the bit to clear accumulated dust and debris from the hole, which improves cutting efficiency and prevents overheating. Wear appropriate personal protective equipment including eye, ear and respiratory protection when drilling.

Usage recommendations

For best results, use the bit with rotary hammers sized for SDS Max accessories and ensure correct rotation speed and hammering force for concrete drilling. Keep the bit straight while drilling to maintain hole accuracy and prolong bit life. Replace the bit if tip wear or damage reduces drilling performance.
