Technical Tips

Drilling large diameter solid rod
  • Drill a pilot hole of 15mm initially
  • Cooling is very important. Use cutting fluid or water. This is one of the biggest reasons for failures.
  • It is very important to remove the shavings when drilling. It is best to regularly withdraw the drill and remove shavings, and then only continue with drilling.
  • Once the 15mm hole is achieved, machine to the required inside diameter using a boring bar on a lathe.
  • Drill a pilot hole of 15mm initially

Example: A 50mm diameter hole is required.

  • Drill a 15mm pilot hole.
  • Now use a boring bar on a lathe to reach the required size.
