Makita SDS-Max Drill Bit 36 x 780 x 920 mm — 6-blade Maxi MAK model B-30293

Makita SDS-Max Drill Bit 36 x 780 x 920 mm — 6-blade Maxi MAK model B-30293 is a heavy-duty SDS-Max rotary hammer drill bit designed for professional masonry and concrete work. With a nominal diameter of 36 mm and extended working lengths, this drill bit fits SDS-Max hammer systems and features a six-blade Maxi MAK geometry to facilitate rapid material removal and stable drilling in demanding applications.

Advantages

The six-blade Maxi MAK geometry ensures efficient debris evacuation and reduces vibration during drilling, increasing penetration speed and prolonging tool life. Hardened cutting edges and a robust body construction provide durability under continuous load. Designed for SDS-Max hammer systems, the bit delivers reliable coupling and power transfer for heavy-duty drilling tasks in concrete and reinforced masonry.

Suitable for

• Drilling large-diameter holes in concrete
• Anchoring and rebar installation in masonry
• Heavy-duty demolition pre-drilling
• Construction and civil engineering tasks requiring SDS-Max tools

Key specifications

• Nominal diameter: 36 mm
• Overall lengths (references): 780 mm and 920 mm
• Shank type: SDS-Max compatible
• Tip geometry: 6-blade Maxi MAK
• Intended materials: concrete, reinforced concrete, masonry

How to use

Select an SDS-Max rotary hammer with appropriate power and operating mode, install the drill bit by inserting and locking the SDS-Max shank into the tool chuck, and set the hammer rotation mode as required. Start drilling at low speed to establish the hole, then apply steady pressure and allow the hammer action and the Maxi MAK geometry to remove material. Periodically withdraw the bit to clear dust and debris and to check drilling alignment. Use correct protective equipment and follow the tool manufacturer's safety instructions while operating.

Usage recommendations

For best results, use cooling and dust extraction where possible, avoid excessive lateral pressure to prevent premature wear, and match the drill length to the task to maintain rigidity. Replace the bit if cutting performance visibly declines or if the tip shows significant wear.
