Baildon DIN 338 RN NWKa Metal Drill Bit 6.4 mm, HSS (S)

The Baildon DIN 338 RN NWKa metal drill bit is a professional-grade cutting tool engineered for precision and reliability in metalworking applications. Manufactured from high-speed steel (HSS), this 6.4 mm drill bit is designed to maintain its structural integrity and sharpness even under demanding operating conditions. Its geometry is optimized for efficient chip evacuation, which helps prevent overheating and ensures smooth, accurate holes in various metallic materials.

Advantages

This drill bit offers exceptional durability due to its high-speed steel construction, which provides superior resistance to wear and heat compared to standard carbon steel bits. The precision-ground tip ensures quick centering and reduced walking on the workpiece surface, leading to cleaner results. Its robust design allows for consistent performance in both industrial settings and professional workshops, making it a dependable choice for repetitive drilling tasks.

Suitable for

• Drilling holes in structural steel and iron
• General metal fabrication and workshop maintenance
• Precision drilling in non-ferrous metals
• Professional industrial manufacturing processes

When it may not be suitable

This drill bit is specifically optimized for metalworking and may not perform optimally when used on extremely hard materials like hardened steel or ceramics, which require specialized carbide tooling. It is also not intended for use on masonry, concrete, or soft wood, where different flute geometries are necessary for effective material removal.

Key specifications

• Diameter: 6.4 mm
• Material: High-speed steel (HSS)
• Standard: DIN 338
• Type: RN NWKa
• Application: Metal drilling

How to use

To achieve the best results, ensure the drill bit is securely fastened in the chuck of your power tool. Mark the drilling point clearly on the workpiece and use a center punch to create a small indentation, which helps the bit start accurately. Apply steady, moderate pressure while maintaining a consistent drilling speed appropriate for the material thickness. It is recommended to use a suitable cutting oil or lubricant to reduce friction, extend the life of the bit, and improve the finish of the hole.

What to consider before purchase

• Verify the required hole diameter for your specific project
• Ensure your drill chuck is compatible with a 6.4 mm shank
• Check that your power tool speed settings match the requirements for HSS bits

Usage recommendations

Always wear appropriate eye protection and safety gear when operating drilling equipment. Regularly inspect the drill bit for signs of wear or dullness to maintain drilling efficiency and prevent damage to the workpiece.
