Makita SDS-Max Drill Bit 19x400x540mm, 6-Blade

The Makita SDS-Max drill bit, measuring 19x400x540mm, is a high-performance tool designed for demanding drilling applications in concrete and masonry. Featuring a specialized 6-blade head geometry, this drill bit ensures exceptional drilling speed and precise hole centering. It is engineered to withstand the high torque and impact energy of professional SDS-Max rotary hammers, providing reliable performance in heavy-duty construction environments.

Advantages

The primary advantage of this drill bit is its advanced 6-blade design, which significantly improves debris removal and reduces vibration during operation. This configuration prevents the bit from jamming in reinforced concrete and ensures a smoother drilling process. The robust steel construction offers high resistance to wear and heat, extending the service life of the tool even under continuous professional use. Furthermore, the SDS-Max shank provides a secure and efficient power transfer from the rotary hammer to the bit, minimizing energy loss.

Suitable for

• Drilling into reinforced concrete
• Masonry and brickwork applications
• Heavy-duty construction and renovation projects
• Installation of large-diameter anchors

When it may not be suitable

This drill bit is not intended for use with standard rotary hammers that utilize SDS-Plus chucks, as it is specifically designed for the larger SDS-Max system. It is also not suitable for drilling into wood, metal, or soft materials, as the aggressive carbide geometry is optimized exclusively for mineral-based building materials.

Key specifications

• Diameter: 19 mm
• Working length: 400 mm
• Total length: 540 mm
• Shank type: SDS-Max
• Head design: 6-blade carbide tip

How to use

Insert the drill bit into the SDS-Max chuck of your rotary hammer until it clicks into place. Ensure the hammer is set to the rotary-hammer mode. Apply steady, moderate pressure while drilling, allowing the 6-blade head to clear debris effectively. Avoid excessive side pressure to prevent bit deflection or damage to the carbide tips.

What to consider before purchase

• Verify that your rotary hammer is compatible with the SDS-Max shank system.
• Ensure the 19mm diameter matches the requirements of your anchors or installation project.
• Check that the 400mm working length is sufficient for the thickness of the material you intend to drill.

Usage recommendations

Always wear appropriate personal protective equipment, including safety goggles and hearing protection, when operating a rotary hammer. Periodically remove the bit from the hole during deep drilling to clear accumulated dust and prevent overheating.
