Baildon HSS-E Co5 Stainless Steel Drill Bit DIN 338 RN NWKa 5.1 mm

The Baildon HSS-E Co5 stainless steel drill bit is a professional-grade tool engineered for precision drilling in demanding metal applications. With a diameter of 5.1 mm and a composition featuring 5% cobalt, this drill bit provides exceptional hardness and thermal stability, making it a reliable choice for machining stainless steel and other high-strength alloys. It adheres to the DIN 338 RN NWKa standard, ensuring consistent geometry and performance for industrial and workshop environments.

Advantages

The primary benefit of this drill bit is its high cobalt content, which significantly enhances heat resistance during prolonged drilling operations. This prevents the tool from softening under high temperatures, thereby extending its service life and maintaining cutting efficiency. The robust construction ensures minimal deflection and high dimensional accuracy, allowing for clean and precise holes in tough materials that would typically cause standard drill bits to wear out rapidly.

Suitable for

• Drilling stainless steel and acid-resistant steel
• Machining high-strength alloy steels
• Industrial manufacturing and metal fabrication
• Precision workshop tasks requiring high durability

When it may not be suitable

This drill bit is specifically optimized for hard, tough metals and may not be the most cost-effective choice for drilling soft materials like wood, plastic, or aluminum, where standard HSS bits would suffice. Additionally, it is not intended for use in masonry or concrete applications.

Key specifications

• Material: HSS-E Co5 (5% Cobalt)
• Diameter: 5.1 mm
• Standard: DIN 338 RN NWKa
• Application: Stainless steel and high-strength alloys

How to use

To achieve the best results, ensure the drill bit is securely mounted in a stable drill press or a high-quality hand drill. Use a suitable cutting fluid or lubricant to reduce friction and heat buildup, which is essential when working with stainless steel. Apply steady, consistent pressure and maintain a moderate drilling speed to prevent work hardening of the material. Always ensure the workpiece is firmly clamped to avoid vibration or bit breakage.

What to consider before purchase

• Verify the required hole diameter for your specific project
• Ensure your drilling equipment is compatible with the bit shank size
• Consider purchasing multiple units if performing high-volume production
• Check that your drill speed settings are appropriate for cobalt-alloy bits

Usage recommendations

For optimal performance and longevity, always use a high-quality cutting oil and avoid excessive force, which can lead to premature dulling or breakage of the drill bit.
