Makita B-57473 SDS Plus Drill Bit 6.5 mm

The Makita B-57473 SDS Plus drill bit, with a 6.5 mm diameter, is a precision-engineered tool designed for high-performance drilling in metal. Built to meet the rigorous demands of professional construction and renovation projects, this drill bit offers exceptional durability and efficient material removal. Its robust construction ensures that users can achieve clean, accurate holes consistently, making it a reliable addition to any toolkit for those working with SDS Plus rotary hammers.

Advantages

This drill bit features a high-speed steel (HSS) composition that provides superior heat resistance and longevity during demanding tasks. The inclusion of a split point design allows for faster, more accurate starts without the bit walking across the surface of the material. By utilizing this specialized geometry, the bit maintains its sharpness over extended periods, reducing the need for frequent replacements and ensuring consistent output in professional environments.

Suitable for

• Drilling precise holes in metal surfaces
• Professional construction and renovation projects
• Applications requiring high-speed steel performance
• Use with SDS Plus rotary hammer drills

When it may not be suitable

This drill bit is specifically designed for metal applications and is not intended for masonry, concrete, or stone drilling. Furthermore, it must not be used in impact mode, as the percussion force can damage the bit or the material being worked on.

Key specifications

• Diameter: 6.5 mm
• Material: High Speed Steel (HSS)
• Compatibility: SDS Plus rotary hammers
• Tip geometry: Split point
• Usage mode: Rotary only (no impact)

How to use

To use the Makita B-57473, insert the bit securely into the SDS Plus chuck of your rotary hammer. Ensure the tool is set to rotary-only mode, as the bit is not designed to withstand impact force. Position the split point at the desired drilling location and apply steady, controlled pressure. Maintain a consistent speed to prevent overheating and ensure the longevity of the high-speed steel edge.

What to consider before purchase

• Verify the required hole diameter for your specific application
• Ensure your power tool is compatible with the SDS Plus shank system
• Confirm that your project involves metal drilling rather than masonry

Usage recommendations: Always wear appropriate eye and ear protection when operating power tools. Keep the drill bit clean and free of debris after use to maintain its cutting efficiency. Avoid applying excessive side pressure during the drilling process to prevent bit breakage.
