Drill Bit A Forged Tool 09084065 100906100 Alpen-Maykestag

Case of Alpen Cobalt Nirosta Drill Bits, 6 pieces, designed for drilling hard and tough materials such as stainless and acid-resistant chrome-nickel steels. The set contains cobalt (nirosta) bits with diameters 2.0, 3.0, 4.0, 5.0, 6.0 and 8.0 mm and comes in a compact case for storage and transport. Cobalt construction provides high resistance to breakage and elevated temperatures, making the bits suitable for intensive use on demanding materials.

Advantages

Special sharpening ensures efficient chip evacuation and improved cutting accuracy, while the geometry promotes reliable self-centering. The cobalt material increases wear resistance and heat tolerance, enabling faster drilling progress and longer tool life when working with stainless and other hard steels.

Suitable for

• Drilling stainless steel and acid-resistant chrome-nickel steels
• Metalworking where high heat and wear resistance are required
• Professional and DIY projects requiring precise, clean holes

How to use

Choose the correct diameter for the required hole and secure the drill bit in a compatible chuck. Use appropriate cutting speed and feed for stainless or hardened steels, apply steady pressure, and allow the bit to cool periodically to avoid overheating. Use cutting fluid or lubricant when drilling stainless or tough materials to improve chip evacuation and extend tool life.

Usage recommendations

For best results, start with a pilot hole when drilling large diameters, maintain recommended speeds for cobalt bits, and use adequate clamping and coolant. Inspect bits regularly for wear and replace any damaged bit to maintain drilling accuracy and safety.
