Drill Bit Makita SDS‑MAX 35 mm MA‑D‑34126 for rotary and demolition hammers

Makita SDS‑MAX 35 mm drill bit MA‑D‑34126 is designed for use with SDS‑MAX rotary and demolition hammers to bore large diameter holes in concrete, masonry and natural stone. The 35 mm diameter allows efficient drilling for anchor installation, pipe and conduit passage, and fastening tasks on construction sites or during renovation work. The SDS‑MAX shank ensures secure retention in compatible hammer chucks and reliable transfer of impact energy for medium to heavy-duty drilling operations.

Advantages

The SDS‑MAX configuration provides fast and secure bit changes and minimizes slippage during hammering. The 35 mm cutting diameter results in fewer passes when enlarging holes compared with smaller bits, reducing total job time. The bit geometry and hardened steel construction deliver consistent drilling performance and extended service life when used in recommended materials and modes. Compatibility with rotary and demolition hammers gives flexibility across drilling and chiselling tasks.

Suitable for

• Drilling large-diameter holes for mechanical anchors and chemical anchors in concrete
• Creating openings for pipes, conduits and cable pass-throughs in masonry and stone
• Preparatory holes for demolition or renovation when using SDS‑MAX demolition hammers
• Tasks on construction sites, installation works and structural repairs

Key specifications

• Shank type: SDS‑MAX compatible shank for hammer chucks
• Cutting diameter: 35 mm for large hole drilling
• Intended materials: concrete, masonry and natural stone
• Applicable modes: rotary hammer drilling and demolition hammer impact modes

How to use

Fit the bit into a compatible SDS‑MAX rotary or demolition hammer following the tool manufacturer's instructions and ensure the bit is fully seated and locked. Select the appropriate drilling mode (hammer drilling for concrete and masonry). Start drilling at low speed to establish position, then apply steady axial pressure while allowing the hammer action to advance the bit. Use periodic withdrawal to clear dust and debris from the hole and to prevent overheating. For through-holes or deep drilling, use intervals to remove accumulated material and inspect the bit condition.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection and dust mask) and consider dust extraction or wet drilling methods when working with concrete or masonry. Match the bit diameter to anchor and pipe sizes, and check compatibility with the hammer's rated impact energy to ensure safe and efficient operation.
