Drill bit Bosch 2608669077 6 mm HSS

HSS twist drill bit Bosch 2608669077 with a 6 mm diameter is designed for precise metal drilling tasks. Made from high-speed steel (HSS), the bit provides increased wear resistance and heat tolerance during continuous drilling. It is suitable for use with handheld drills and drill presses and produces accurate round holes in steel, cast iron, non-ferrous metals and similar materials for assembly, repair and fabrication work.

Advantages

The high-speed steel construction ensures balanced hardness and toughness for long tool life and reliable cutting performance. The 6 mm diameter offers a common size for fasteners and fittings, delivering consistent hole roundness and dimensional stability. The twist geometry provides efficient chip evacuation and stable drilling progress, while heat resistance reduces the risk of premature wear when drilling at medium speeds.

Suitable for

• Drilling through mild and alloyed steels
• Working with non-ferrous metals such as aluminum and brass
• General assembly and maintenance tasks
• Handheld drilling and drill press operations

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 6 mm
• Type: Twist drill bit
• Suitable materials: Steel, non-ferrous metals, cast iron
• Use: Metal drilling for assembly and repair

How to use

Select a drill and appropriate speed for the metal being worked: lower speeds for harder steels, higher speeds for softer non-ferrous materials. Secure the workpiece and mark the drilling point. Use a center punch for accurate start if required. Fit the 6 mm HSS twist drill bit into the chuck, tighten securely, and apply steady, even pressure while drilling. Periodically retract to clear chips and reduce heat buildup; use cutting fluid when drilling harder steels or during prolonged operation to prolong tool life and improve hole quality.

Usage recommendations

For best results, match drill speed to material hardness, use cutting fluid when drilling steel, and avoid excessive pressure to prevent bit breakage. Inspect the bit for wear or deformation before use and replace if cutting performance degrades.
