Drill Bit Smart SDS‑Plus Quattro 12 x 450/400 mm

Drill Bit Smart SDS‑Plus Quattro 12 x 450/400 mm is a purpose-designed SDS‑Plus masonry bit with a 12 mm diameter and 450 mm overall length (400 mm working length). It is intended for use in SDS‑Plus rotary hammers and combines Quattro tip geometry with a robust flute design to improve drilling efficiency and chip evacuation when working in concrete, brick and similar materials. The construction supports drilling deep or through holes for anchors, rebar installation clearance and other installation tasks.

Advantages

The Quattro tip geometry provides stable centring and efficient debris removal for faster penetration with reduced binding. Hardened and precision-ground cutting edges extend bit life and maintain consistent performance during repetitive drilling. The SDS‑Plus shank enables secure tool engagement and quick change between compatible rotary hammers. Overall design balances rigidity for straight holes with flute geometry that clears dust to reduce overheating and wear.

Suitable for

• Drilling through concrete and reinforced concrete
• Making holes in masonry and brickwork for anchors and dowels
• Installation and repair tasks requiring deep or through holes
• Construction and electrical/plumbing installations where SDS‑Plus rotary hammers are used

Key specifications

• Diameter: 12 mm
• Overall length: 450 mm
• Working length: 400 mm
• Shank type: SDS‑Plus
• Tip geometry: Quattro tip for improved centring and chip removal
• Material: hardened and precision-ground cutting edges suitable for concrete and masonry

How to use

Insert the SDS‑Plus shank fully into the rotary hammer chuck until it locks. Select hammer or rotary‑hammer mode appropriate for drilling in concrete and apply steady axial pressure while allowing the tool to do the work. Withdraw the bit periodically to clear debris in deeper holes and to avoid overheating. For through holes, ensure the opposite side is supported or cleared of dust before completing the hole. Inspect the bit after extended use and replace if cutting edges are worn or if the shank is damaged.

Usage recommendations

Use with compatible SDS‑Plus rotary hammers at recommended speed and impact settings for 12 mm bits. Wear appropriate personal protective equipment including eye, hearing and respiratory protection. For best results in reinforced concrete, use progressive drilling with intermittent clearing of debris to maintain performance and prolong bit life.
