When it may not be suitable

This drill bit is not designed for drilling through metal, wood, or ceramic tiles, as the tip geometry is specifically optimized for masonry. It should not be used with standard drill chucks that lack the SDS-Plus interface.

Key specifications

• Diameter: 5 mm
• Shank type: SDS-Plus
• Material compatibility: Concrete, masonry, brick

How to use

Insert the drill bit into the SDS-Plus chuck of your hammer drill until it clicks into place. Ensure the drill is set to hammer-drill mode for optimal performance in concrete. Apply steady, moderate pressure while drilling to allow the bit to cut through the material effectively. Periodically retract the bit from the hole during deep drilling to clear out accumulated dust and debris, which helps prevent overheating.

What to consider before purchase

• Verify that your power tool is compatible with the SDS-Plus shank system.
• Ensure the 5 mm diameter meets the specific requirements of your anchors or fasteners.
• Check the depth capacity of the bit against your intended application.

Usage recommendations

Always wear appropriate personal protective equipment, including safety glasses and hearing protection, when operating power tools. Keep the drill bit clean and store it in a dry place to prevent corrosion.
