Drill Bit Makita SDS‑MAX 12×200×340 mm, 6‑cut MAXI (B-05260)

Makita SDS‑MAX 12×200×340 mm, 6‑cut MAXI is a heavy‑duty SDS‑MAX drill bit designed for rotary hammers with SDS‑MAX chucks. The 12 mm diameter with 200 mm working length and 340 mm overall length provides a balance between reach and stiffness for drilling through concrete, reinforced concrete and masonry. The six‑cut MAXI head geometry improves dust and debris evacuation and stabilizes the bit during high‑power hammer drilling for consistent hole quality.

Advantages

The six‑cut MAXI head design enhances cutting efficiency and reduces jamming by directing dust and chips away from the cutting edge. Optimized flute geometry supports faster debris removal and cooler drilling, while the SDS‑MAX shank ensures secure, slip‑free engagement with compatible rotary hammers. The bit is manufactured to deliver consistent hole diameter and reliable performance in repetitive professional applications.

Suitable for

• Drilling holes in concrete for anchors and dowels
• Creating passage holes in masonry and brickwork
• Preparation of openings for rebar or bolt insertion in renovation works
• Heavy‑duty construction and industrial drilling tasks

Key specifications

• Diameter: 12 mm
• Working length: 200 mm
• Overall length: 340 mm
• Shank type: SDS‑MAX compatible
• Head geometry: six‑cut (6‑cut) MAXI for improved debris evacuation
• Primary material: hardened tool steel with wear‑resistant cutting edges

How to use

Mount the drill bit into an SDS‑MAX rotary hammer according to the tool manufacturer’s instructions, ensuring a secure fit before operation. Position the drill perpendicular to the work surface and start drilling at low speed to create an initial guide point, then apply steady pressure while allowing the hammer action to do the cutting. Periodically withdraw the bit to clear dust and chips from the hole, which helps maintain drilling speed and prevents overheating. Use appropriate personal protective equipment such as eye and hearing protection and dust extraction or a mask when drilling masonry and concrete.

Usage recommendations

For best results in reinforced concrete, use controlled feed pressure and intermittent withdrawal to clear debris. Pair this SDS‑MAX bit with a rotary hammer that provides sufficient impact energy for the material being drilled, and consider using dust extraction when working indoors to maintain a clean and safe work environment.
