Drill Bit Makita SDS‑MAX 22 mm MA-B-20074 for SDS‑MAX Hammer Drills

Makita SDS‑MAX 22 mm MA-B-20074 is a drill bit designed for SDS‑MAX hammer drills and rotary‑hammer tools. With a 22 mm diameter, this masonry bit is intended for drilling holes in concrete, reinforced concrete, brick and other similar hard materials using percussion combined with rotation. It fits SDS‑MAX chucks and is intended for trade, construction and renovation tasks that require reliable anchoring and fast hole-making in structural materials.

Advantages

The SDS‑MAX 22 mm bit offers a robust carbide tip geometry optimized for rapid removal of material and sustained cutting performance. Its shank and flute design provide stable engagement with SDS‑MAX chucks and efficient evacuation of dust and debris during drilling. The bit is made for use under high-impact loads and repeated operations, giving consistent hole diameter and straight drilling in demanding jobsite conditions.

Suitable for

• Drilling anchor and fixing holes in concrete and reinforced concrete
• Creating holes in brick, blockwork and mortar joints
• Construction and renovation work requiring SDS‑MAX rotary‑hammer drilling
• Professional trade and site applications with SDS‑MAX tools

Key specifications

• Diameter: 22 mm
• Shank type: SDS‑MAX compatible
• Intended materials: concrete, reinforced concrete, masonry, brick
• Application: rotary‑hammer drilling with hammering action
• Typical use: anchor and fixation holes, structural drilling

How to use

Select an SDS‑MAX compatible rotary‑hammer tool and secure the bit into the chuck according to the tool manufacturer's instructions. Mark the drilling point and start drilling at low speed to establish the position, then apply steady pressure and use the hammer‑drill mode for efficient penetration into concrete or masonry. Withdraw periodically to clear dust and allow the flutes to evacuate debris; when drilling deep holes, remove the bit occasionally to improve dust extraction and avoid overheating. Use appropriate drill speeds and feed pressure recommended for a 22 mm masonry bit and for the specific material being drilled.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, hearing protection and respiratory protection when drilling. Use dust extraction or wet drilling where possible to reduce airborne dust. Inspect the bit for wear or damage before use and replace when the cutting edges or shank are worn to maintain drilling accuracy and safety.
