Drill bit Bosch 2608900197, HSS metal drill, 3 mm diameter

Twist drill bit Bosch 2608900197 is a 3 mm diameter HSS metal drill designed for accurate hole making in thin sheets, profiles and general workshop workpieces. Manufactured from high-speed steel, the bit is suitable for use with handheld and benchtop drills and fits standard three-jaw chucks. Its geometry and material composition are intended to deliver reliable cutting performance and improved wear resistance when drilling ferrous and non-ferrous metals.

Advantages

The high-speed steel construction offers a balance of hardness and toughness for sustained cutting in metal. The 3 mm diameter provides precise pilot and finish holes with reduced material deformation. Compatible with common drill chucks and both handheld and bench drills, this bit is convenient for routine workshop tasks. The flute geometry aids chip evacuation to reduce clogging during continuous drilling.

Suitable for

• Drilling holes in thin steel sheets and plates
• Creating pilot holes in metal profiles and frames
• General-purpose workshop and maintenance drilling
• Handheld and benchtop drilling applications

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Cylindrical shank for standard three-jaw chucks
• Drill type: Twist drill for metal
• Diameter: 3 mm
• Intended materials: Ferrous and non-ferrous metals, thin sheet metal

How to use

Secure the drill bit in a compatible chuck ensuring it is centered and tightened. Mark the drilling position on the workpiece and, when drilling metal, use appropriate cutting speeds and steady feed pressure to avoid overheating. For better results on thicker or harder metals, use cutting fluid to reduce friction and aid chip evacuation. Withdraw the bit periodically when drilling deep holes or long runs to clear chips and cool the cutting edge.

Recommendations

Use protective equipment such as safety glasses and gloves, clamp the workpiece securely, and select recommended drilling speeds for a 3 mm HSS bit when working with different metal types. Store the bit in a dry place to prevent corrosion and inspect for wear or damage before use.
