Drill Bit Makita SDS‑MAX 36 x 400 x 540 mm, 6‑cut (B-05511)

Makita SDS‑MAX 36 x 400 x 540 mm, 6‑cut (B-05511) is a long masonry drill bit designed for use with SDS‑MAX rotary hammers. The 36 mm diameter and extended length suit through and deep drilling in concrete, reinforced concrete and natural stone. A six‑cut head geometry promotes steady drilling, improved chip evacuation and consistent hole quality for anchoring, dowel and conduit installations.

Advantages

The six‑cut head provides balanced cutting action and reduced wandering at startup. The long shank and extended overall length allow deep and through drilling without the need for extension accessories. Hardened cutting edges and optimized flute design improve durability and clear debris efficiently, maintaining drilling speed and reducing clogging. The SDS‑MAX connection ensures secure attachment to compatible rotary hammers and reliable torque transfer during heavy‑duty tasks.

Suitable for

• Drilling through concrete and reinforced concrete
• Making anchor and dowel holes
• Creating passages for electrical conduits and plumbing
• Deep or through drilling in renovation and construction works

Key specifications

• Diameter: 36 mm
• Working length (effective drill length): 400 mm
• Overall length: 540 mm
• Shank type: SDS‑MAX compatible
• Head design: six‑cut tip for improved chip removal
• Intended materials: concrete, reinforced concrete, natural stone

How to use

Install the drill bit into an SDS‑MAX rotary hammer following the tool manufacturer's instructions until it locks securely. Select appropriate rotation and impact settings for masonry work. Start drilling at low pressure to establish a guide hole, then apply steady axial pressure while allowing the tool to do the cutting. Periodically withdraw the bit to clear dust and chips, especially when drilling deep holes, and check bit condition during extended use. Use appropriate safety equipment including eye protection, hearing protection and dust control measures.

Usage recommendations

For best results, use this SDS‑MAX bit with a rotary hammer rated for long‑reach masonry drilling and match hammer settings to the material hardness. When drilling reinforced concrete, moderate continuous pressure and frequent withdrawal for chip clearing will extend bit life. Employ dust extraction or wet drilling methods where required by worksite regulations to reduce airborne silica dust.
