Drill bit ALPEN Cassette HSS Cobalt Forte TM 6 mm, solid high-speed steel with cobalt

ALPEN Cassette HSS Cobalt Forte TM 6 mm drill bit is a solid high-speed steel cutting tool with added cobalt designed for drilling metal and other hard materials. The 6 mm diameter bit is manufactured for dimensional accuracy and edge retention, offering improved heat resistance and wear performance compared with standard HSS bits. It is suitable for use in hand drills, drill presses and many industrial drilling applications where consistent hole quality and longer tool life are required.

Advantages

The cobalt alloy in this HSS bit increases hardness at elevated temperatures, enhancing resistance to softening during high-speed or heavy feed operations. Its solid high-speed steel construction provides good rigidity and precise centring for accurate holemaking. Compared with ordinary HSS bits, this product offers extended wear life and more stable cutting performance when working with harder metals.

Suitable for

• Drilling stainless steel and alloy steels
• Drilling mild steel and ferrous materials
• Workshop and industrial drilling operations
• Use in hand drills and drill presses

Key specifications

• Material: solid high-speed steel with cobalt enhancement
• Diameter: 6 mm
• Intended application: metal and other hard materials
• Tool type: twist drill bit

How to use

Secure the drill bit in the chuck of the hand drill or drill press, ensuring correct alignment and firm clamping. Select a rotation speed appropriate for the material being drilled and apply consistent feed pressure; when drilling harder metals, use lower speeds and steady pressure to avoid overheating. Use cutting fluid or coolant as appropriate to extend tool life and improve chip evacuation. Retract the bit periodically in deep holes to clear chips and reduce heat buildup.

Usage recommendations

For best results when drilling stainless steel or other hard alloys, run the drill at moderate speed with cutting fluid and avoid excessive feed rates. Inspect the bit for wear before use and replace when cutting edges become dull to maintain hole quality and reduce the risk of breakage.
