Drill Bit Makita SDS‑MAX 30 x 200 x 340 mm, 6‑cut Maxi, model B-05321

Makita SDS‑MAX 30 x 200 x 340 mm, 6‑cut Maxi (model B-05321) is a rotary hammer drill bit designed for SDS‑MAX chucks. With a nominal diameter of 30 mm, a working length of 200 mm and a total length of 340 mm, this bit is intended for drilling in concrete and masonry. The 6‑cut Maxi tip geometry and the SDS‑MAX shank provide controlled drilling progress and effective removal of dust and debris during rotary hammer operation.

Advantages

The 6‑cut Maxi design delivers consistent cutting performance and improved centring when starting holes. SDS‑MAX connection ensures secure fitment in compatible rotary hammers and quick bit changes. The combination of working length and overall length balances reach and stability for common construction tasks while maintaining efficient dust evacuation through the flutes.

Suitable for

• Drilling anchor holes in reinforced or non‑reinforced concrete
• Creating through‑holes and passage holes in masonry
• Clearing around rebar where precise hole diameter is required
• Professional heavy‑duty construction and renovation applications

Key specifications

• Shank type: SDS‑MAX
• Tip geometry: 6‑cut Maxi
• Intended material: concrete and masonry

How to use

Install the bit into the SDS‑MAX chuck of a compatible rotary hammer according to the tool manufacturer's instructions, ensuring it locks securely. Select the rotary or rotary‑hammer mode appropriate for the material and apply steady pressure while allowing the tool to do the work; avoid excessive force which can reduce bit life. Periodically withdraw the bit to clear dust from the hole and prevent clogging of the flutes. For holes encountering reinforcement, use appropriate methods to avoid damage to the bit and workpiece.

Usage recommendations

Use appropriate personal protective equipment including eye and ear protection and a dust extraction system when possible. Verify compatibility of the SDS‑MAX shank with your rotary hammer and match drilling speed and impact settings to the material to extend bit service life.
