Drill bit Makita SDS‑MAX 16 x 200 x 340 mm 6‑flute (B-05234)

Makita SDS‑MAX 16 x 200 x 340 mm 6‑flute drill bit is a purpose-built masonry bit for SDS‑MAX rotary hammer drills. With a 16 mm diameter, 200 mm working length and 340 mm overall length, it is intended for drilling through concrete, brick and natural stone. The 6‑flute geometry enhances removal of drill cuttings and supports efficient progress when performing heavy hammer drilling and chiselling tasks.

Advantages

The 6‑flute profile improves dust evacuation from the hole and reduces clogging, which contributes to faster drilling and more consistent bite in dense materials. Hardened cutting edges and reinforced core construction provide increased durability under sustained impact loads. The SDS‑MAX shank ensures secure locking in compatible rotary hammers, minimising slippage and enabling reliable power transfer from tool to bit.

Suitable for

• Drilling holes in reinforced and non‑reinforced concrete
• Masonry work in brick and block walls
• Creating anchor and fixing holes for heavy fixtures
• Renovation and construction where deep or long holes are required

Key specifications

• Bit diameter: 16 mm
• Working length (usable drilling depth): 200 mm
• Overall length: 340 mm
• Shank type: SDS‑MAX compatible
• Flute design: 6‑flute geometry for improved dust removal
• Material/finish: hardened steel cutting edges with reinforced core (manufacturer design)

How to use

Install the bit into an SDS‑MAX rotary hammer according to the tool manufacturer’s instructions, ensuring the shank is fully engaged and locked. Use the hammer drilling mode for masonry and concrete; apply steady axial pressure without forcing the bit to allow the hammer action to break material effectively. Withdraw the bit periodically to clear accumulated dust and avoid overheating. When encountering reinforcement, reduce feed pressure and use short bursts to avoid bit damage.

Usage recommendations

Wear appropriate personal protective equipment including safety glasses, hearing protection and a dust mask when drilling. For extended drilling sessions use dust extraction or a vacuum attachment to maintain visibility and reduce airborne silica. Match drill speed and feed pressure to the material; consult the rotary hammer’s manual for recommended operating ranges.
