Drill bit Makita SDS‑MAX 35 x 400 x 540 mm 6‑flute for masonry and concrete

Makita SDS‑MAX 35 x 400 x 540 mm 6‑flute drill bit is designed for use with SDS‑MAX rotary hammers to drill precise holes in concrete, masonry and natural stone. The 35 mm diameter and 400 mm working length allow reliable anchoring and through‑hole drilling for construction tasks. The six‑flute geometry improves dust evacuation and stabilises the bit during high‑torque rotary‑hammer operation, supporting consistent drilling speed and reduced jamming.

Advantages

The 6‑flute design promotes more effective removal of drill dust and debris, helping to maintain drilling progress and reduce clogging. A long working length provides access to deeper anchoring points and through holes without frequent bit changes. The bit is compatible with SDS‑MAX chucks and is engineered for stable performance in reinforced concrete and masonry. Hardened cutting edges offer wear resistance and extended service life under typical construction use.

Suitable for

• Drilling anchor and dowel holes in concrete and blockwork
• Through‑hole drilling for conduit and pipe installations
• Creating holes in natural stone and masonry for fastening systems
• Work with SDS‑MAX rotary hammers on construction sites and renovation projects

Key specifications

• Shank type: SDS‑MAX compatible
• Diameter: 35 mm
• Working length: 400 mm
• Total length: 540 mm
• Flute configuration: 6‑flute for improved dust evacuation
• Suitable materials: concrete, reinforced concrete, masonry, natural stone

How to use

Secure the drill bit into the SDS‑MAX chuck of a compatible rotary hammer, ensuring the bit locks in place. Select the rotary or rotary‑hammer mode according to the tool and material; use hammering action when working in concrete or masonry. Apply steady pressure without forcing the bit, allow the tool to do the cutting, and periodically withdraw the bit to clear accumulated dust if drilling deep holes. Use appropriate drilling speeds and cooling intervals for continuous heavy use to reduce overheating and wear.

Usage recommendations

Use personal protective equipment including safety glasses, hearing protection and dust mask. For best results in reinforced concrete, start with a smaller pilot hole if practical, and remove reinforcing bar obstructions carefully. Inspect the bit for wear or damage before use and replace when cutting edges are worn to maintain drilling accuracy and safety.
