Baildon Metal Drill Bit DIN 338 RN NWKa 5 mm HSS

The Baildon metal drill bit, model DIN 338 RN NWKa, is a high-quality 5 mm drilling tool engineered for precision and longevity. Manufactured from high-speed steel (HSS), this drill bit is designed to withstand the rigors of demanding metalworking tasks while maintaining its cutting edge. Its robust construction ensures consistent performance, making it a reliable choice for both professional workshops and industrial environments where accuracy and durability are paramount.

Advantages

This drill bit offers exceptional heat resistance and structural integrity, which are critical when working with hard materials. The precision-ground geometry facilitates efficient chip removal, preventing overheating and ensuring a smooth drilling process. Its design adheres to the DIN 338 standard, guaranteeing compatibility with a wide range of standard drill chucks and power tools, which enhances its versatility across various mechanical projects.

Suitable for

• Drilling holes in structural steel and iron
• General metal fabrication and repair work
• Workshop maintenance and mechanical assembly
• Precision drilling in non-ferrous metals

This drill bit may not be suitable for drilling into hardened steel, ceramics, or masonry, as these materials require specialized carbide-tipped or diamond-coated bits. It is also not intended for use in high-impact hammer drilling applications, which could cause the bit to fracture.

Key specifications

• Diameter: 5 mm
• Material: High-speed steel (HSS)
• Standard: DIN 338 RN NWKa
• Application: Metal drilling

To use the drill bit, ensure it is securely fastened in the drill chuck. Mark the center of the hole to be drilled to prevent the bit from wandering. Apply steady, moderate pressure while maintaining a consistent speed appropriate for the material being drilled. It is advisable to use a cutting fluid or lubricant to reduce friction and heat, which will significantly extend the lifespan of the tool.

What to consider before purchase

• Verify the required hole diameter for your specific project
• Ensure your drill chuck is compatible with a 5 mm cylindrical shank
• Check if the material you are drilling is compatible with HSS tools

Usage recommendations: Always wear appropriate eye protection when drilling metal. Periodically clear the drill bit of metal shavings to maintain optimal cutting efficiency and prevent the bit from binding in the hole.
