Drill Bit Makita SDS‑MAX 18 mm for Concrete, model MA‑D‑33962

Makita SDS‑MAX 18 mm for Concrete, model MA‑D‑33962 is a dedicated rotary‑hammer drill bit designed for drilling through concrete, reinforced concrete and masonry. With an 18 mm diameter and SDS‑MAX shank, this bit is built to be used with compatible SDS‑MAX rotary hammers for medium to heavy‑duty drilling tasks. The carbide tip and flute geometry are engineered to remove debris efficiently and maintain drilling performance in demanding construction environments.

Advantages

The SDS‑MAX 18 mm bit offers reliable drilling depth and consistent hole quality when used in concrete and similar materials. Its SDS‑MAX connection ensures secure mounting in rotary hammers, enabling effective transfer of impact energy. The carbide‑tipped head improves wear resistance and extends service life compared with standard steel bits, while the optimized flute design helps evacuate dust and slurry to sustain drilling speed.

Suitable for

• Drilling anchor and fixing holes in concrete
• Electrical and plumbing installation openings
• General construction and renovation work in masonry
• Professional use with SDS‑MAX rotary hammers on medium to heavy tasks

Key specifications

• Diameter: 18 mm
• Shank type: SDS‑MAX
• Intended material: concrete, reinforced concrete, masonry
• Tip material: carbide
• Typical application: rotary hammer drilling for anchors, conduits and service penetrations

How to use

Fit the drill bit into an SDS‑MAX compatible rotary hammer following the tool manufacturer's instructions until it locks securely. Select the hammer or hammer‑drill mode appropriate for concrete, start drilling with steady axial pressure, and allow the tool to do the work—avoid excessive force that can shorten bit life. Periodically withdraw the bit to clear accumulated dust and check the bit condition; replace the bit if the carbide tip is damaged or excessively worn.

Usage recommendations

Use personal protective equipment including eye protection, hearing protection and a dust mask or extraction when drilling. For longer life and improved performance, use appropriate drilling speed and allow cooling intervals when performing prolonged drilling tasks in hard or reinforced concrete.
