Makita B-47503 SDS-Plus Drill Bit 8x400 mm

The Makita B-47503 SDS-Plus drill bit is a professional-grade tool engineered for high-performance drilling in concrete, brick, and masonry. Measuring 8 mm in diameter and 400 mm in total length, this drill bit is designed to provide stability and precision during deep-hole drilling applications. Its robust construction ensures longevity even when used with powerful rotary hammers, making it a reliable choice for construction sites and renovation projects.

Advantages

This drill bit features a specialized geometry that facilitates efficient dust removal, which prevents clogging and allows for faster drilling speeds. The high-quality carbide tip is designed to withstand the impact forces generated by SDS-Plus rotary hammers, ensuring consistent performance and reduced wear over time. Its design minimizes vibration, which helps in maintaining accuracy and reducing operator fatigue during extended use.

Suitable for

• Drilling holes in reinforced concrete
• Masonry and brickwork installation
• Anchoring applications in construction
• Renovation and electrical installation work

This drill bit may not be suitable for drilling into metal, wood, or ceramic tiles, as the carbide tip and SDS-Plus shank are specifically optimized for masonry materials. Using this bit on inappropriate surfaces may result in damage to the tool or the material being drilled.

Key specifications

• Diameter: 8 mm
• Total length: 400 mm
• Shank type: SDS-Plus
• Material compatibility: Concrete, brick, masonry

To use the Makita SDS-Plus drill bit, insert the shank into the SDS-Plus chuck of your rotary hammer until it clicks into place. Ensure the tool is set to the hammer-drill mode before starting. Apply steady, moderate pressure while drilling, allowing the bit to do the work. Periodically retract the bit from the hole to clear out accumulated dust, which helps maintain drilling efficiency and prevents the bit from overheating.

What to consider before purchase

• Verify that your power tool is equipped with an SDS-Plus chuck system
• Ensure the 400 mm length is appropriate for the depth of the holes required
• Check that the 8 mm diameter matches the size of the anchors or fasteners being used

Usage recommendations

Always wear appropriate personal protective equipment, including safety glasses and hearing protection, when operating rotary hammers. Ensure the drill bit is securely locked in the chuck before starting the tool to prevent slippage or injury.
