Import Air Tools — Buy in Bulk from Supplier in China

The ARX-831L 7-Inch Air Angle Grinder from Shanghai Clever Co., Ltd. is a pneumatic-powered grinding tool built for industrial metalworking, delivering a free speed of 7,000 RPM through a 7-inch (178 mm) abrasive disc. The unit employs a safety lever type throttle mechanism that requires deliberate two-hand engagement, reducing accidental start-up risk in factory environments. This grinder is designed for manufacturing, automotive repair, and metal fabrication operations where sustained stock removal and surface conditioning are required.

The grinder body is constructed from aluminium alloy die-casting with a composite rear housing, keeping unit weight low for extended horizontal grinding without excessive operator fatigue. The 7-inch disc size permits a broad work swath and rapid material removal on weld seams, castings, and plate steel. Standard accessories include a side handle (multi-position) and a guard that adjusts without tools, though the specific guard diameter and spindle thread (typically M14 or 5/8 inch - 11 for this class) should be confirmed with the supplier. Air consumption at load and the recommended hose inner diameter are not stated in the listing data.

Typical buyers include metal fabrication shops, shipyard maintenance crews, and automotive OEM suppliers who need portable, non-electric grinders for explosion-risk areas or where electrical supply is unreliable. The grinder runs on compressed air at standard shop pressures, typically 6.3 bar (90 psi), though the exact air inlet thread and required cubic feet per minute (CFM) rating are not specified here. Buyers should verify these figures, along with vibration levels (measured in m/s² under EN 60745), before committing to volume orders.

Shanghai Clever Co., Ltd. is located at 7 D, Ai-ho Building, 629 Ling-Ling Road, Shanghai 200030, China. The supplier is classified under the imported supplier tier and holds a harbor trust tier on the platform. Notably, the response rate is recorded at 0.00 percent with an average response time of zero hours, indicating that the supplier has not yet engaged with buyer enquiries through the platform messaging system. This profile does not list any verification badges, trade assurance status, or years in operation.

The company address places it within Xuhui District, a central Shanghai commercial zone rather than an industrial manufacturing park, which may suggest trading or distribution activity rather than in-house production. No factory size, employee count, annual revenue, or client references are provided in the source data, and none should be assumed. Buyers should conduct direct due diligence on production capabilities, quality control processes, and whether the ARX-831L is manufactured under the company's own tooling or sourced from a third-party OEM.
