Snappy Tools Adjustable Low Friction Non-Marring Rotating Countersink Ball Bearing Depth Stop Collar. Proudly Made in The USA

The Snappy Tools Adjustable Low Friction Non-Marring Rotating Countersink Ball Bearing Depth Stop Collar is an effective tool for Consistent depth countersinks. Made in the USA, this tool does not cause any damage to the wood surface, thanks to its non-marring ball bearing. Its clamping mechanism is clever and helps prevent any accidental slipping during use. However, there are a few issues with the product. When setting the depth for screw heads to be flush with the wood surface, the clamp is not fully on the counterbore shaft, which can be a concern, especially with smaller screws. Additionally, some reviewers mentioned that the stop collar was not square to the counterbore shaft, but this did not affect operation. The product's special set screw is a small, loose part that could easily be lost. Overall, the Snappy Tools Adjustable Low Friction Non-Marring Rotating Countersink Ball Bearing Depth Stop Collar is a functional tool that is well-suited for a large run of screws. While it is worthwhile for ease of use, it may not be worth the investment for smaller projects.
