FAQs – Frequently Asked Questions:

• Is this drill bit designed for dry or wet cutting?
  • It’s primarily a dry core bit, but light water use may extend life and improve cutting efficiency.

• What type of drill should I use this with?
  • It should be paired with a rotary drill or core drill using a suitable arbor and pilot bit.

• Can I use this on reinforced concrete?
  • Not recommended. Reinforced concrete can damage non-specialist bits—use a rebar-rated bit instead.

• Does the bit come with an arbor and pilot drill?
  • No, this listing is for the core bit only. You’ll need a compatible Blue Spot arbor system.

• What makes diamond core bits better for masonry?
  • The diamond segment edge provides faster, cleaner cuts through hard materials with less wear.

• Can I use this with an SDS drill?
  • Only if the drill supports core drilling attachments. Most SDS drills will require an adaptor.

• How long will the bit last?
  • With proper use and no contact with metal reinforcement, it will provide long-lasting cutting life.

• What colour is the bit?
  • The bit is finished in a recognisable Blue Spot blue, making it easy to identify in your kit.

• Is it suitable for DIY as well as trade?
  • Yes, it’s robust enough for trade-level use, but accessible for confident DIYers with the right equipment.

• Why choose a 152mm size?
  • It’s ideal for larger installations such as extractor fans, tumble dryer vents, and waste pipe systems.
