FAQs

What is the benefit of using cobalt drill bits?

Cobalt drill bits offer superior heat resistance and wear resistance compared to standard HSS bits, making them ideal for drilling hard materials like stainless steel.

What materials can I drill with this set?

You can drill into alloyed and non-alloyed steel, stainless steel, cast iron, cast steel, and acid- and heat-resistant steels.

What is the purpose of the split-point tip?

The split-point tip provides active cutting and perfect centering without wandering, making for more precise drilling.

How do I extend the life of my drill bits?

Use cutting fluid, apply appropriate pressure, select the correct speed, and store the bits properly.

Are these drill bits suitable for use with a drill press?

Yes, these bits are suitable for use with both drill drivers and drill presses.

What is the shank type of these drill bits?

These drill bits have a cylindrical shank system, where the shank diameter equals the drill bit diameter.

Troubleshooting

Drill bit is dulling quickly.

Reduce drilling speed, apply cutting fluid, and check the material for hardness. Consider replacing the bit if it's worn.

Drill bit is breaking.

Reduce pressure, ensure the drill is perpendicular to the surface, and check the drill bit's condition. Use the correct drill bit size for the pilot hole.

Drill bit is wandering or not centering.

Use a center punch to create a starting point, and apply steady pressure. Make sure you are using a drill bit with a split point tip.

Pros and Cons

Pros

  • High wear resistance for extended bit life.
  • Suitable for a wide range of materials, including stainless steel.
  • Efficient chip removal for faster and cleaner drilling.
  • Precise drilling due to the split-point tip.
  • Comes in an organized metal case for easy storage and access.

Cons

  • Requires proper drilling technique to maximize bit life and performance.
  • May require slower drilling speeds compared to bits designed for softer materials.
  • Cobalt bits can be more expensive than standard HSS bits.
  • The 19-piece set may not include all the sizes needed for every project.

Setup, Compatibility & Care

  1. Setup:
  • Insert the appropriate size drill bit into your drill chuck.
  • Ensure the bit is securely tightened.
  • Select the correct speed setting for the material you are drilling (slower speeds for harder materials like stainless steel).
  1. Compatibility:
  • Compatible with standard drill drivers and drill stands.
  • Use with alloyed and non-alloyed steel, stainless steel, cast iron, cast steel and acid- and heat-resistant steels.
  1. Care:
  • Apply cutting fluid or oil when drilling to reduce heat and friction.
  • Avoid excessive force to prevent bit breakage.
  • Store the drill bits in the provided metal organizer to prevent damage.
  • Clean the bits after each use to remove debris and prevent corrosion.
