SDS‑MAX Concrete Drill Bit 25 mm Makita MA‑D‑34045

SDS‑MAX 25 mm concrete drill bit from Makita is designed for heavy-duty rotary hammer drilling in concrete, masonry and natural stone. The 25 mm diameter provides a balance between hole size and drilling speed for anchor installation, through-holes or cable and pipe passages. The SDS‑MAX shank ensures firm retention in compatible rotary hammers and fast tool changes on job sites.

Advantages

The carbide tip and optimised flute geometry deliver reliable material removal and extended life under continuous use. The robust body construction resists bending and wear during impact drilling, while the standardised SDS‑MAX connection offers secure seating and efficient power transfer. This drill bit is practical for repetitive tasks thanks to consistent hole diameter and stable drilling performance.

Suitable for

• Drilling through reinforced and non-reinforced concrete for anchors and fasteners
• Creating passages for electrical conduits and plumbing
• Renovation and installation work on masonry and natural stone

Key specifications

• Diameter: 25 mm
• Shank system: SDS‑MAX compatible
• Intended material: concrete, masonry, natural stone
• Tip material: carbide cutting head
• Application type: rotary hammer / impact drilling

How to use

Install the bit into an SDS‑MAX compatible rotary hammer according to the tool manufacturer's instructions, ensuring it is fully seated and locked. Mark the drilling position, start at low speed to create a guide, then apply steady pressure while allowing the hammer action to do the work. Periodically withdraw the bit to clear dust and prevent overheating; for deep holes use a drill with blow-out or use compressed air to clean the hole. Wear appropriate personal protective equipment including eye and hearing protection, and follow safe drilling practices.

Usage recommendations

For prolonged life of the drill bit, avoid excessive lateral pressure and let the rotary hammer's impact force progress the cut. When drilling reinforced concrete, slow advancement and regular clearing of debris will reduce wear on the carbide tip. Match the bit diameter to anchor and fixture specifications to ensure proper fit and performance.
