KEIL 61404KEIL Cobalt Steel Drill Bits Set 338

The KEIL Cobalt Steel Drill Bits Set 338 is a professional-grade solution engineered for demanding metalworking tasks. These drill bits are crafted from high-quality cobalt-enriched steel, providing exceptional heat resistance and structural integrity when drilling into hard materials such as stainless steel and various alloyed metals. Designed for precision and longevity, this set ensures consistent performance in industrial and workshop environments.

Advantages

The primary advantage of these cobalt steel drill bits is their superior thermal stability, which prevents the material from softening during high-friction drilling operations. This durability allows for extended tool life and maintains sharp cutting edges even when working with tough, high-tensile metals. The robust construction minimizes the risk of breakage and ensures accurate, clean hole creation in challenging materials where standard high-speed steel bits might fail.

Suitable for

• Drilling into stainless steel
• Working with alloyed metals
• Industrial metal fabrication
• Professional workshop maintenance
• Precision drilling tasks in hard materials

This set may not be suitable for drilling into soft materials like wood or plastic, as the high-performance cobalt geometry is specifically optimized for metal. Additionally, it is not intended for masonry or concrete applications, which require specialized carbide-tipped drill bits.

Key specifications

• Material: Cobalt-enriched steel
• Diameter: 10 mm
• Length: 13.3 cm
• Application: Metalworking

To use these drill bits effectively, ensure the workpiece is securely clamped to prevent vibration or movement during the drilling process. Apply consistent, moderate pressure and use a suitable cutting fluid or lubricant to reduce heat buildup and extend the life of the drill bit. Always start with a center punch to ensure precise positioning and prevent the bit from wandering on the metal surface.

What to consider before purchase

• Verify the required diameter for your specific project
• Ensure compatibility with your drill chuck size
• Consider the material hardness of your workpiece
• Check the warranty terms for your specific user category

For optimal results and to maximize the lifespan of your KEIL cobalt drill bits, always operate at the recommended drilling speeds for the specific metal type and ensure the bit remains properly lubricated throughout the operation.
