Extended Product Information

FAQs

Can I use these on stainless steel?

Yes, the bi-metal construction is designed to cut through stainless steel, provided you use the correct drill speed and adequate lubrication.

What is the maximum cutting depth?

These holesaws are standard depth; consult the sidewall measurement of the specific saw to ensure it clears the thickness of your material.

Are the pilot drills replaceable?

Yes, the pilot drills are standard replacements that can be secured using the set screws in the mandrels.

Can I use this with a standard battery-powered drill?

Yes, but ensure your drill has enough torque for larger diameter holes, particularly when cutting metal.

Is the storage case water-resistant?

The case is designed for durability and organization, but it is not waterproof; keep it in a dry tool cabinet.

Troubleshooting

Holesaw is binding or getting stuck in material

Reduce feed pressure, ensure the drill is kept perfectly perpendicular to the surface, and ensure you are using a cutting fluid for metal applications.

Pilot drill keeps coming loose

Ensure the set screw on the mandrel is tightened with a hex key, and check if the flat section of the pilot drill bit is properly aligned with the screw.

Excessive heat during cutting

Slow down the drill RPM and increase the use of cutting oil to dissipate heat and prevent premature dulling of the teeth.

Pros and Cons

Pros

  • High-speed steel edge for increased durability
  • Comprehensive size range covers most standard requirements
  • Robust case with protective padding
  • Strong electron beam welds prevent premature failure

Cons

  • Large kit footprint may be overkill for light domestic use
  • Requires proper cooling/lubrication when cutting stainless steel
  • Fixed mandrel sizes limit compatibility with specialized drill chucks

Setup, Compatibility & Care

To set up your holesaw, select the appropriate mandrel based on the diameter of the saw: the 9.5mm mandrel is typically used for smaller holes, while the 13mm is for larger, higher-torque applications. Always ensure the pilot drill is secured tightly with the provided set screw to prevent slippage.

Care instructions:

  1. After cutting metal, clean metal shavings from the gullets using a wire brush.
  2. Apply a light coat of machine oil to the teeth if storing for long periods to prevent oxidation.
  3. Regularly inspect the mandrels for burrs or damage to ensure they remain centered in your drill chuck.
  4. Keep the storage case latched to prevent moisture and dust ingress.
