Drill Bit SDS‑MAX Makita 32 x 400 x 540 mm, 6‑cut MAXI, model B-05496

Makita SDS‑MAX drill bit 32 x 400 x 540 mm, 6‑cut MAXI (model B-05496) is a rotary‑hammer drill accessory intended for drilling deep, accurate holes in concrete and masonry. The SDS‑MAX shank ensures secure engagement with compatible rotary hammers and demolition tools, while the 6‑cut MAXI carbide tip provides efficient cutting and improved dust removal during heavy‑duty drilling. This bit is designed for professional and advanced DIY applications where robust performance and hole precision are required for anchors, sleeves, conduit runs and similar installations.

Advantages

The 6‑cut MAXI tip design delivers faster penetration and cleaner hole walls compared with standard two‑cut tips, reducing the need for reaming. SDS‑MAX shank offers reliable retention and easy bit changes under load. The bit’s length and drilling diameter are optimized for deep anchoring and through‑hole requirements in reinforced concrete and masonry. Carbide cutting edges are heat‑resistant and wear‑resistant, extending service life in demanding conditions.

Suitable for

• Drilling deep holes in concrete and reinforced concrete for mechanical anchors
• Creating sleeves and conduit passages for electrical and plumbing installations
• Heavy‑duty demolition and renovation tasks requiring precise boreholes
• Professional construction sites and advanced DIY projects using SDS‑MAX rotary hammers

Key specifications

• Shank type: SDS‑MAX
• Cut type: 6‑cut (MAXI) carbide tip
• Drill diameter: 32 mm
• Working length: 400 mm
• Total length: 540 mm
• Intended material: concrete and masonry

How to use

Install the SDS‑MAX bit into a compatible rotary hammer according to the tool manufacturer’s instructions, ensuring the shank locks securely. Select hammer‑drill mode and an appropriate speed and impact setting for concrete. Apply steady axial pressure without forcing the bit; allow the hammer action to perform most of the cutting. Periodically withdraw the bit to clear dust and debris and to prevent clogging and overheating. For deep holes, drill in stages if necessary to maintain bit performance and hole quality.

Usage recommendations

Use suitable personal protective equipment including eye protection, hearing protection and dust control measures. Match drilling parameters to the concrete strength and reinforcement presence; for heavily reinforced areas, consider pilot holes or alternative anchoring methods. Store the bit dry and protect the carbide tip from impact when not in use to preserve cutting performance.
