Drill Bit Makita SDS‑MAX 26 x 400 x 540 mm, 6‑cut MAXI B-05468

Makita SDS‑MAX 26 x 400 x 540 mm, 6‑cut MAXI B-05468 is a heavy‑duty drill bit designed for use with SDS‑MAX rotary hammers. With a nominal diameter of 26 mm and an overall length that supports deep drilling, this 6‑cut MAXI design provides efficient material removal and improved drilling straightness in concrete, masonry and similar hard building materials. The bit is intended for large‑diameter holes needed in construction, installation and renovation work where reliable penetration and chip evacuation are required.

Advantages

The six cutting edges reduce vibration and provide more balanced cutting action compared with two‑ or three‑cut designs, resulting in straighter holes and faster drilling progress. The SDS‑MAX shank enables secure, tool‑compatible retention in rotary hammers, allowing high impact energy transfer during hammer drilling. The geometry of the flute and cutting head is optimized for removal of dust and debris from deep holes, which helps maintain drilling speed and reduces jamming.

Suitable for

• Drilling 26 mm diameter holes in reinforced and non‑reinforced concrete
• Creating anchor and dowel holes for installations
• Through holes for pipes and conduits in masonry
• Renovation tasks requiring repeatable, deep drilling

Key specifications

• Diameter: 26 mm
• Working length: 400 mm
• Overall length: 540 mm
• Shank type: SDS‑MAX compatible
• Cut configuration: 6‑cut (MAXI) for improved chip removal and straighter drilling
• Intended material: concrete, masonry and similar hard substrates

How to use

Select a compatible SDS‑MAX rotary hammer rated for the required drilling diameter and impact energy. Securely insert the SDS‑MAX shank into the tool chuck according to the rotary hammer manufacturer’s instructions. Mark the drilling position, start at low speed to create a guide indent if needed, then apply steady pressure while operating the hammer mode for percussive drilling. Periodically withdraw the bit to clear accumulated dust from the hole and allow cooling; continue until the required depth is reached.

Usage recommendations

Use appropriate personal protective equipment including eye and hearing protection, and a dust extraction system or wet drilling where feasible to reduce silica dust exposure. For reinforced concrete, consider using a rebar‑cutting protocol or a specialized bit when encountering steel reinforcement. Store the bit in a dry place and inspect cutting edges before use; replace if excessively worn or damaged to maintain drilling performance.
