Makita B-57401 SDS-Plus Drill Bit 3 mm

The Makita B-57401 SDS-Plus drill bit is a precision-engineered tool designed for drilling small-diameter holes in masonry and concrete. With a 3 mm diameter, this drill bit is crafted from high-speed steel to provide durability and consistent performance during demanding construction and installation projects. Its design ensures efficient material removal, allowing for clean and accurate results when working with compatible rotary hammer drills equipped with an SDS-Plus chuck system.

Advantages

This drill bit offers exceptional reliability due to its high-speed steel construction, which maintains sharpness and structural integrity over extended periods of use. The inclusion of a split point design facilitates easier centering and prevents the bit from wandering on the surface, ensuring high precision from the moment drilling begins. Its compatibility with the SDS-Plus system allows for quick and secure tool changes, minimizing downtime on the job site and enhancing overall productivity for professional users.

Suitable for

• Drilling precise 3 mm holes in masonry
• Installation work in concrete structures
• Renovation projects requiring small diameter anchors
• Professional construction and assembly tasks

When it may not be suitable

This drill bit is not intended for use with impact or hammer action enabled on the drill, as this can damage the bit or the material. It is also not suitable for drilling through hardened steel, wood, or ceramic tiles, as the geometry is specifically optimized for masonry applications.

Key specifications

• Diameter: 3 mm
• Material: High Speed Steel (HSS)
• Shank type: SDS-Plus
• Tip geometry: Split point
• Compatibility: Rotary hammers with SDS-Plus chuck

How to use

Insert the drill bit into the SDS-Plus chuck of your rotary hammer until it clicks into place. Ensure the drill is set to rotation-only mode, as the impact function must be disabled to prevent damage to the bit. Position the split point at the desired mark and apply steady, moderate pressure while maintaining a perpendicular angle to the surface. Allow the bit to cut through the material without forcing it, and periodically retract the bit to clear dust from the hole to maintain drilling efficiency.

What to consider before purchase

• Verify that your power tool is compatible with the SDS-Plus chuck system.
• Ensure the 3 mm diameter meets the specific requirements of your fasteners or anchors.
• Confirm that your project involves masonry or concrete rather than metal or wood.

Usage recommendations

Always disable the hammer or impact mode on your rotary hammer when using this drill bit to ensure longevity and prevent breakage.
