Drilling 25 mm diameter holes through steel pipe.

Watch how we drill 25 mm diameter holes through toughened steel tube with a wall thickness of 5 mm, the hole is drilled through both walls.

To use traditional coolant would have made an absolute intolerable mess, with coolant running down the tube creating a safety hazard and customer quality issues. The manufacturer here decided to apply Unist’s “Near Dry Drilling” technology, through spindle MQL (minimum quantity lubrication). The drilling cell incorporates two Unist Tornado units that send atomized oil particles down through the drive motor spindle and then through the drill  exiting at the drill tips.

No Mess, Dry chips, extended tool life and no thermal cracking of the carbide tips are just a few of the many benefits gained by employing today’s technology to steel drilling applications. This system runs on Coolube 2210EP at an oil consumption rate of 20 ml per drilling hour.

Also at the same time check out the benefits of using Coolube over other cheaper products that are on the market.

Changing from Alucobond/Composite panel to Solid Aluminium Sheet

Do you find yourself having to Route 3mm solid Aluminium sheet in preference to Alucobond/Composite panel? If you are experiencing any of the following you need to talk to our John Barker (Managing Director) of Unist Australia.

  • Ragged cutting
  • Burning out cutters
  • Breaking router bits
  • Terrible surface finish
  • Just the inability to get the job done

We understand your problem, you need to lubricate the routing cutter with our 3 nozzle Coolubricator.

For help on this matter call John Barker on 02 8850 2022 or email [email protected].
