Part 3/7:
The Doy model struggled under vibration from an impact wrench, opening its jaws enough to measure 1.21 mm of gap. In contrast, the Irwin brand ($16) displayed superior handling, minimizing movement at 1.11 mm sideways and 0.9 mm vertically.
Performance Across Different Brands
Mid-Range Tools
Amazon Basics ($18): Claimed precision engineering, performing effectively with just over 1 mm of slop.
Craftsman ($19): Less vertical movement at 0.76 mm, showing commendable performance in tests.
Heavyweights in Performance
- Vanquish and Crescent ($22 each): Both promised enhanced gripping power and performed admirably but revealed significant jaw movement during trials.
