Drill Bit Makita SDS‑Max 40 x 400 x 540 mm, 6‑cut (B-05533)

Makita SDS-Max 40 x 400 x 540 mm, 6-cut (B-05533) is a heavy-duty rotary drill bit designed for professional masonry work. The bit has a 40 mm diameter, a 400 mm working length and a 540 mm overall length, and features a six-cut carbide tip geometry that improves cutting efficiency in concrete and reinforced concrete. The SDS-Max shank provides secure fitting and efficient power transfer for compatible rotary hammers, making the bit suitable for extended drilling tasks and demanding jobsite conditions.

Advantages

The six-cut tip design gives consistent drilling performance and helps maintain a straight bore while delivering high material removal rates. The long working length allows drilling deep holes and through-drilling without the need for extensions. Manufactured by Makita, the bit is built for durability and repeated use in professional settings, and the SDS-Max shank ensures quick installation and positive engagement with rotary hammers that accept this interface.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Through-drilling and deep anchor hole preparation
• Professional masonry and construction site drilling
• Use with SDS-Max rotary hammers for heavy-duty applications

Key specifications

How to use

Select a compatible SDS-Max rotary hammer and secure the bit into the tool according to the hammer manufacturer’s instructions. Mark the drilling position, start drilling at low speed to establish the hole, then apply steady pressure and appropriate hammering action as required for the material. Periodically extract the bit to clear dust and debris from the hole to maintain cutting efficiency and prevent overheating. For deep holes, remove accumulated debris frequently to improve removal of cut material.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask when drilling. Match drill speed and hammer settings to the material and avoid excessive lateral force to prevent premature wear. For best performance in reinforced concrete, use a rotary hammer with sufficient impact energy and follow manufacturer guidance for carbide tip tools.
