This Draper HSS drill bit is suitable for drilling into steel, cast iron, non-ferrous metals, and plastics.

HSS stands for High-Speed Steel, a type of alloy steel known for its hardness and resistance to heat.

These are international standards that ensure the drill bit meets specific quality, dimensional, and performance requirements for drill bits.

While it might create a hole in wood, this bit is specifically designed and optimized for metals and plastics. Using wood-specific drill bits is recommended for best results in wood.

Store the drill bits in their original packaging or a dedicated bit organizer in a dry place to prevent rust and damage.

Yes, this drill bit is compatible with standard cordless drills, provided the drill has a chuck that can securely grip the 3.0mm shank.

Recommended speed varies by material and drill size. Generally, slower speeds are used for harder materials and larger diameters, while faster speeds are suitable for softer materials and smaller diameters. Consult your drill manufacturer's guidelines or online resources for specific recommendations.

Ensure you are using appropriate speed and pressure for the material. Excessive force or binding can cause breakage. Consider using a cutting fluid for harder metals.

Check that the drill bit is sharp and undamaged. Ensure it is centered correctly in the drill chuck and perpendicular to the material surface. Verify the selected speed is appropriate.

Reduce drilling speed and apply intermittent pressure to allow the bit and material to cool. Use a cutting lubricant, especially for metals.
