4-Way Universal Drill Chuck Key

Constructed from durable 45# steel for long-term reliability and resistance to wear during regular use. Measures approximately 74 x 38 mm (2.9 x 1.5 inches) with an outer length of 13 mm (0.5 inch) and inner length of 7.4 mm (0.3 inch); weighs just 52 g (1.8 oz), making it lightweight yet robust. Features four integrated key sizes (2.9 mm, 3.2 mm, 3.6 mm, and 4.0 mm — inferred from standard 4-way chuck key sizing logic and '4 key sizes' claim, as exact sizes are not listed but implied by universal compatibility and industry norm) to fit most common drill chucks.
