Drill Bit Makita SDS‑MAX 16 x 400 x 540 mm, 6‑cut (B-05402)

Makita SDS‑MAX 16 x 400 x 540 mm, 6‑cut (B-05402) is a masonry drill bit designed for rotary hammers with SDS‑MAX chucks. The 16 mm diameter and 400 mm working length make it suitable for through‑and‑flush drilling in concrete, stone and masonry. The six‑cut head geometry improves cutting efficiency and dust removal, extending tool life and maintaining steady progress in demanding drilling tasks.

Advantages

The six‑cut (6‑edge) head design delivers precise centring and stable drilling with reduced vibration. Optimised flute geometry promotes efficient removal of dust and chips, which helps maintain drilling speed and reduces heat build‑up. Built from hardened tool steel and finished for wear resistance, this SDS‑MAX bit offers long service life when used in appropriate applications. Compatibility with standard SDS‑MAX chucks ensures easy mounting and reliable retention during heavy‑duty operation.

Suitable for

• Drilling through concrete for anchor and fixing installations
• Creating holes in stone and masonry for service penetrations
• Construction and renovation projects requiring repeated deep drilling
• Use with SDS‑MAX rotary hammers on jobsites and in workshop settings

Key specifications

• Shank type: SDS‑MAX compatible
• Diameter: 16 mm
• Working length: 400 mm
• Total length: 540 mm
• Head type: six‑cut (6‑edge) carbide tip
• Application materials: concrete, stone, masonry

How to use

Fit the bit into an SDS‑MAX rotary hammer according to the tool manufacturer's instructions and ensure a secure lock before starting. Mark the drilling point and begin at low speed to establish the hole, then apply steady pressure and allow the hammer action to do the work. Periodically withdraw the bit to clear dust and chips, especially when drilling deep holes, to maintain cutting performance and avoid overheating. Use appropriate protective equipment, including eye, ear and respiratory protection, and secure the workpiece if possible.

Usage recommendations

For best results in reinforced concrete, use progressive drilling technique: start with a pilot depth, clear debris, then continue to final depth. Match drill speed and force to material hardness and the rotary hammer's rating. Replace the bit when the carbide edge shows significant wear or when drilling becomes slower despite correct technique.
