## Long description

Makita SDS‑MAX 20 x 400 x 540 mm drill bit with a 6‑cut MAXI tip is a rotary‑hammer masonry bit designed for drilling through concrete, stone and similar substrates with SDS‑MAX chuck systems. The 20 mm diameter and extended length enable deep anchor and dowel holes, while the six‑cut carbide tip improves cutting efficiency and hole quality. This bit is intended for professional construction and renovation tasks where stable, repeatable performance is required.
Advantages
The six‑cut MAXI tip reduces vibration and provides balanced rotation for straighter holes and more efficient material removal. Optimized flute geometry clears dust and debris effectively during deep drilling, maintaining steady progress and reducing the chance of bit jamming. Robust shank design ensures reliable retention in SDS‑MAX rotary hammers and supports sustained use under heavy‑duty conditions.
Suitable for
Drilling through reinforced and non‑reinforced concrete
Creating deep anchor and dowel holes for mechanical fixings
Installing masonry anchors in stone and brick
Professional construction and renovation drilling tasks
Key specifications
Diameter: 20 mm
Working length: 400 mm
Total length: 540 mm
Tip type: 6‑cut (six‑edge) MAXI carbide tip
Shank system: SDS‑MAX compatible
Intended material: concrete, stone, brick
How to use
Install the drill bit into an SDS‑MAX rotary hammer according to the tool manufacturer's instructions, ensuring the shank is fully seated and locked. Mark the drilling point, position the bit perpendicular to the surface, and start at low speed to establish the pilot. Use hammer‑drilling mode and apply steady, moderate pressure; allow the tool to do the work rather than forcing the bit. For deep holes, withdraw the bit periodically to clear accumulated dust and prevent overheating. Wear appropriate personal protective equipment including eye, ear and respiratory protection.
Usage recommendations
For best results use in rotary hammers with SDS‑MAX chucks and select appropriate drill speed and impact settings for concrete. When encountering reinforcement, proceed with steady pressure and consider using a rebar‑cutting accessory if required. Regularly inspect the carbide tip for wear and replace the bit if cutting performance degrades.
