Review on Maximize Precision: Unveiling the POWERTEC 71492 Collar Design Markings by John Roberts

Revainrating 4 out of 5

Work slow but work great

Works great as intended and includes all popular sizes. Be careful when using this product, test for holes and take your time. The drill heats up, which causes it to expand and, when reused, can shift the stops. For this reason I drilled through the board. I love that it's a hinge rather than a set screw and that it's a better and cheaper option compared to a power drill.

Pros
  • Hex Shank Drill Bit
Cons
  • Crumpled Package
