Bosch HSS Metal Drill Bit - 5.0mm - 2 608 577 165

This drill bit is suitable for drilling clearance and pilot holes in alloyed and non-alloyed steel, non-ferrous metals, cast steel, cast iron, and plastics.

The PointTeQ tip is self-centering, providing an accurate start without wandering. Its innovative design also enables a faster drilling rate and generates less heat and wear, helping the tip stay sharper for longer.

The highly elastic body is designed to reduce the risk of breakage, especially for drill bits below 6 mm in diameter, making them more resilient during use.

The black-oxide coating on the flute aids in fast chip removal. This helps to prevent chip buildup, reduce heat generation, and maintain the sharpness of the drill bit.

It features a cylindrical shank, which is compatible with standard three-jaw drill chucks commonly found on drill drivers and drill stands.

This drill bit is designed for standard steels and cast iron. For hardened steel, a specialized drill bit (e.g., cobalt or carbide-tipped) would typically be required.

Use the appropriate drill speed and pressure for the material, ensure effective chip removal by keeping the flute clear, and use cutting fluid when drilling into tougher metals. Avoid excessive bending or forcing the bit.

Ensure the self-centering PointTeQ tip is engaged correctly. Apply steady, consistent pressure and start drilling at a slower speed until the tip bites into the material.

Check if the drill bit is dull. Ensure you are using the appropriate drill speed for the material. Clean the flute to remove any packed chips that may be obstructing removal. Consider using a cutting fluid for lubrication, especially in harder metals.

Reduce drilling speed and apply less pressure. Ensure the flute is clear of chips for efficient heat dissipation. Use a suitable cutting fluid or coolant.

Reduce excessive side pressure or bending force. Ensure the material is adequately supported. For bits below 6mm, exercise extra caution with pressure and avoid forcing the bit through tough sections.
