Graphite 54T555 Extended Wood Drill Bit 4 x 400 mm

The Graphite 54T555 extended wood drill bit is a professional-grade tool engineered for precision drilling in wood and wood-based materials. Measuring 4 mm in diameter and 400 mm in total length, this drill bit is specifically designed to reach deep areas that standard-length bits cannot access. Its robust construction provides the necessary stability for deep-hole drilling, ensuring clean and accurate results for various woodworking and construction tasks.

Advantages

This drill bit offers exceptional performance due to its specialized geometry, which facilitates efficient chip removal during deep drilling operations. The extended length allows for precise work in thick timber or complex furniture structures without the need for additional extensions. Its high-quality material composition ensures long-lasting durability and resistance to wear, maintaining sharpness even after repeated use in demanding professional environments.

Suitable for

• Deep-hole drilling in solid wood
• Carpentry and furniture assembly projects
• Construction work involving thick wooden beams
• Installation of long fasteners or cable routing through wood

When it may not be suitable

This drill bit is not intended for use on metal, concrete, or masonry, as these materials will cause rapid dulling or damage to the cutting edges. It is also not recommended for use with high-impact hammer drills, as the slender 4 mm diameter may bend or break under excessive force.

Key specifications

• Diameter: 4 mm
• Total length: 400 mm
• Material application: Wood and wood-based materials
• Design: Extended length for deep drilling

How to use

To use the Graphite 54T555, securely mount the drill bit into the chuck of your power drill or drill press. Ensure the tool is centered and tightened properly. Begin drilling at a moderate speed, applying steady and consistent pressure to allow the bit to cut through the material. Periodically retract the drill bit from the hole during the process to clear out wood chips, which prevents overheating and binding. Always ensure the workpiece is firmly clamped to avoid movement during the drilling operation.

What to consider before purchase

• Verify that your drill chuck is compatible with a 4 mm shank diameter.
• Ensure the 400 mm length is appropriate for the depth of your specific project.
• Confirm that the material being drilled is wood or a wood-based composite.

Usage recommendations

Always wear appropriate eye protection and ensure the drill bit is sharp before starting your work. For the best results, maintain a perpendicular angle to the surface to prevent the bit from wandering or breaking.
