Troubleshooting

Hole size is inaccurate

Verify that the pivot arm is locked exactly on the desired measurement marking on the scale before beginning your cut.

Tool is struggling to cut

Check the cutting bit for signs of wear or dullness and replace it with the included spare bit if necessary.

Pivot arm slips during operation

Ensure the hex-key locking screw is fully tightened to prevent movement during rotation.

Pros and Cons

Pros

  • Versatile size range for various ducting applications
  • Easy installation in standard drill chucks
  • Clear, molded measurement scales for accuracy
  • Durable black powder coating resists wear
  • Includes essential spare parts for field maintenance

Cons

  • Limited to 24-gauge steel and 26-gauge stainless steel

Setup, Compatibility & Care

To set up the tool, ensure the pilot bit is tightened securely into the center of the pivot arm. Use the included L-style hex-key to loosen the locking screw, slide the arm to your desired diameter using the molded scales, and retighten firmly before drilling. The tool is compatible with any standard electric or cordless drill chuck. After use, inspect the cutting bit for dullness; if performance degrades, swap it out with the included replacement bit. Clean the unit regularly to remove metal shavings and ensure the bearings remain free-spinning for future jobs.
