Robust construction and materials: Made from chrome-molybdenum steel with a non-slip safety sleeve. Forged for durable performance, it provides strong wear resistance for both manual and electric operation. High impact and wear resistance: Constructed from cold-drawn industrial steel with integral forging and enhanced torsional strength, delivering reliable performance under heavy use. Safety features: Includes a safety protective sleeve and a securely fixed locking pin. The sleeve has a safety groove that helps maintain a slip-free grip, providing extra protection and peace of mind during operation. Double clamp function: Features a double-clamp design with a square-tooth profile for a secure hold. Offers additional stability and grip to make loosening and tightening easier and more precise. Applications and use scenarios: - Disc changes on angle grinders: quickly and securely loosen or tighten the wheel nut during routine maintenance. - Heavy-duty grinding tasks: robust enough for high-torque work in metal fabrication and construction. - Safety‑conscious maintenance: the included case and fixed locking pin provide a secure, slip-free grip for safer operation.
