When it may not be suitable

This drill bit is not intended for drilling into hardened steel, masonry, or concrete, as it lacks the specific tip geometry and material hardness required for these surfaces. Using it on such materials may result in rapid dulling or breakage of the bit.

Key specifications

• Diameter: 7.0 mm
• Total length: 225 mm
• Material: Steel

How to use

To achieve the best results, ensure the drill bit is securely fastened in the chuck of your power drill or drill press. Mark the drilling point clearly before starting. Begin drilling at a low speed to establish the hole, then gradually increase the speed while maintaining steady, moderate pressure. Avoid applying excessive force, as this can cause the bit to overheat or bend. Periodically retract the bit from the hole to clear away accumulated debris.

What to consider before purchase

• Verify the compatibility of the 7.0 mm diameter with your specific project requirements.
• Ensure your drill chuck is capable of holding a 7.0 mm shank.
• Confirm that the 225 mm length is sufficient for the depth of the material you intend to drill.

Usage recommendations

Always wear appropriate eye protection when operating drilling equipment. Keep the drill bit clean and store it in a dry place to prevent corrosion. If the bit becomes dull, replace it to maintain drilling efficiency and safety.
