Abraboro HSS-Co Cobalt Drill Bit DIN 338 3.0mm

The Abraboro HSS-Co cobalt drill bit is a professional-grade cutting tool engineered for precision drilling in demanding metalworking environments. Manufactured in accordance with DIN 338 standards, this 3.0 mm drill bit features a cobalt-alloyed composition that significantly enhances its structural integrity and thermal stability when working with challenging materials.

Advantages

The primary benefit of this cobalt drill bit is its superior heat resistance, which allows it to maintain a sharp cutting edge even during prolonged operation in hard and alloyed steels. Its robust construction ensures minimal deflection and high dimensional accuracy, providing a reliable solution for tasks that require consistent performance and extended tool life compared to standard high-speed steel bits.

Suitable for

• Drilling into stainless steel and acid-resistant steel
• Processing alloyed and non-alloyed cast iron
• Precision metalworking in industrial and workshop settings
• Creating accurate 3.0 mm diameter holes in hardened metals

When it may not be suitable

This drill bit is not optimized for drilling into soft materials like wood or plastic, where standard HSS bits are more cost-effective. It is also not intended for masonry or concrete applications, as the cutting geometry and material composition are specifically tailored for metal substrates.

Key specifications

• Diameter: 3.0 mm
• Material: HSS-Co (High-Speed Steel with Cobalt)
• Standard: DIN 338
• Application: Hard and alloyed steels

How to use

To achieve the best results, secure the workpiece firmly in a vice to prevent vibration. Use a steady, moderate pressure and a lower rotational speed compared to standard steel bits to prevent overheating and premature wear. It is recommended to use a suitable cutting oil or coolant to extend the lifespan of the bit and ensure a clean finish in the material.

What to consider before purchase

• Verify that your drill chuck is compatible with a 3.0 mm shank diameter.
• Ensure the material hardness does not exceed the recommended limits for HSS-Co tools.
• Consider purchasing multiple bits if working on high-volume production tasks.

Usage recommendations

Always wear appropriate eye protection and ensure the drill bit is properly centered before starting the motor to prevent breakage and ensure operator safety.
