When it may not be suitable

This drill bit is specifically optimized for metalworking and may not perform optimally when used on masonry, concrete, or extremely hard ceramic surfaces. For such materials, specialized masonry or diamond-tipped bits are required to avoid damaging the tool or the workpiece.

Key specifications

• Diameter: 3.3 mm
• Total length: 65 mm
• Material: High-speed steel
• Application: Metal and general materials

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 center of the hole to be drilled using a center punch to prevent the bit from slipping. Apply steady, moderate pressure while maintaining a consistent drilling speed appropriate for the material being worked on. It is recommended to use a cutting fluid or lubricant when drilling through metal to reduce friction, dissipate heat, and extend the service life of the drill bit.

What to consider before purchase

• Verify that your drill chuck is compatible with a 3.3 mm shank diameter
• Ensure the drill bit length is sufficient for the depth of your intended application
• Check the material compatibility to ensure it meets your specific project requirements

Usage recommendations

Always wear appropriate eye protection and safety gear when operating drilling equipment. Regularly inspect the drill bit for signs of wear or dulling, and replace it promptly to maintain drilling accuracy and prevent damage to your power tools.
