Drill bit Smart SDS‑Plus Quattro 10 x 310/250 mm

The Drill bit Smart SDS‑Plus Quattro 10 x 310/250 mm is a rotary and hammer drill accessory designed for SDS‑Plus chucks. It has a quattro tip geometry that improves cutting and material removal when drilling concrete, masonry and natural stone. The bit's overall length is 310 mm with a 250 mm working length, providing sufficient depth for anchor and through‑hole drilling in construction and installation tasks. The design is suited to both professional tradespeople and home users who need a reliable, durable drill bit for repetitive drilling into hard substrates.

Advantages

The quattro tip geometry reduces walking at the start of a hole and enhances chip evacuation, which helps maintain drilling speed and reduces heat build‑up. The SDS‑Plus shank ensures quick, secure fitting in compatible hammer drills and rotary hammers. The long working length allows deep anchor placements and through‑holes without changing accessories, while the robust flute profile supports stable drilling under impact loads. Materials and geometry are selected to balance wear resistance and efficient cutting in concrete and masonry.

Suitable for

• Drilling anchor holes in concrete and reinforced concrete
• Through‑holes for pipes and conduits in masonry walls
• Installing fixtures, brackets and heavy fittings in stone and blockwork
• Professional renovation, construction and maintenance tasks requiring repetitive holes

Key specifications

• Drill type: SDS‑Plus rotary/hammer bit
• Tip geometry: quattro multi‑cut profile for improved penetration and chip removal
• Diameter: 10 mm
• Overall length: 310 mm
• Working length (effective drilling depth): 250 mm
• Suitable materials: concrete, reinforced concrete, masonry, natural stone

How to use

Fit the SDS‑Plus shank into the drill chuck until it locks, ensuring a secure connection. Select hammer mode for concrete and masonry to use the bit's impact‑drilling capability; use rotary mode for drilling without impact in softer stone or when precise start control is required. Start drilling at low speed to establish the hole, then increase speed and apply steady axial pressure without forcing the bit. Periodically withdraw the bit to clear dust and chips from the hole, which helps maintain cutting efficiency and prevents overheating.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask. Match drill speed and hammer force to the material: higher impact for dense concrete, moderate for hollow masonry. Replace the bit when wear reduces cutting performance or when tip damage occurs to avoid enlarged holes or drill overload. For deep holes, periodically withdraw the bit to remove debris and allow cooling.
