Description
The TQC Sheen Dolly Drill for Adhesion Test is a specialized tool designed to prepare coated surfaces for pull-off adhesion testing. It ensures a precise and controlled drilling process around the dolly, allowing accurate isolation of the test area without damaging the surrounding coating.
During adhesion testing, it is essential to eliminate lateral stresses from surrounding coating layers. The dolly drill achieves this by creating a clean, circular cut around the bonded dolly, ensuring that the measured adhesion strength reflects only the bond between the coating and substrate.
Engineered for stability and precision, the tool provides consistent drilling depth and alignment, making it ideal for both laboratory and field applications. It is compatible with standard adhesion test dollies and helps improve the reliability and repeatability of test results.

Why Use a Dolly Drill
Proper surface preparation is critical for accurate adhesion testing. Using a dolly drill helps to:
- Isolate the test area for accurate pull-off results
- Prevent influence from surrounding coating layers
- Improve repeatability and consistency of measurements
- Reduce the risk of coating damage outside the test zone
- Ensure compliance with adhesion testing standards
⸻
How It Works
- Bond the dolly to the coated surface using a suitable adhesive.
- Allow the adhesive to cure fully according to specifications.
- Position the dolly drill over the bonded dolly.
- Align the drill to ensure a centred and even cut.
- Carefully drill around the dolly to isolate the test area.
- Remove any debris from the surface.
- Proceed with the pull-off adhesion test.
