21V 1000N.M high torque cordless impact gun

BS1121 delivers 1000 N·m (740 ft-lbs) of breakaway torque in a cordless impact gun. As a factory-direct supplier with OEM/ODM capability, BISON gives distributors and resellers a competitively priced, private-label-ready product backed by consistent manufacturing quality.

Where the BS1121 delivers real value

Heavy-duty applications demand tools that keep up with production pace. The BS1121 is purpose-built for:

• Automotive & tire service centers: rapid lug nut removal and installation across high-volume daily jobs

• Commercial fleet & truck maintenance: tackling heavily torqued fasteners on axles, suspensions, and chassis components

• Construction & structural assembly: anchoring structural bolts in confined spaces without a compressor or power outlet

• Agricultural & heavy equipment repair: breaking loose rusted or overtorqued hardware on machinery and implements

Why procurement teams choose the BS1121

1000 N·m torque — consistent, not just claimed

At 1000 N·m peak output, the BS1121 handles virtually all standard automotive and industrial fasteners without a secondary tool. Unlike lower-spec wrenches that require multiple passes on stubborn hardware, this level of breakaway torque improves per-technician throughput and reduces job cycle time — a measurable ROI for service-volume operations.

Brushless motor: lower maintenance, longer service life

The brushless motor eliminates the wear points that shorten tool lifespan in high-frequency use environments. Compared to brushed alternatives, brushless designs run cooler, draw less current per cycle, and typically last significantly longer before requiring service — reducing replacement frequency and total cost of ownership for your end customers.

4.0 Ah battery platform — designed to finish the shift

The 21V / 4.0 Ah lithium-ion battery provides extended runtime per charge, supporting continuous operation through demanding work sessions. A no-load speed of up to 2,900 RPM means fast socket engagement without sacrificing control — relevant for technicians completing repetitive fastening tasks across dozens of vehicles or assemblies per day.

Variable speed trigger — precision where it matters

A variable speed trigger allows operators to modulate output for sensitive materials, fine-thread fasteners, or torque-critical applications. This reduces over-tightening incidents, lowers the risk of thread damage, and extends socket and fastener service life — reducing consumable costs in high-volume workshops.

Ergonomics that reduce fatigue and injury risk

At 1000 N·m, reaction force management matters. The BS1121 features an anti-vibration handle and balanced weight distribution to minimize operator fatigue during extended use. Integrated LED work lighting ensures visibility in low-light environments — under vehicle platforms, inside equipment bays, or on night shifts — without requiring secondary lighting equipment.

The business case in summary

The BS1121 impact gun addresses a straightforward procurement equation: your customers need a high-torque cordless wrench that performs reliably across hundreds of cycles, doesn't require compressor infrastructure, and won't generate excessive warranty claims. BISON's manufacturing platform delivers that performance at factory-direct economics — with the flexibility to carry your brand.

Whether you're building a private-label power tool line or supplementing an existing catalog, the BS1121 offers a proven specification at a margin-viable price point. Contact BISON to discuss MOQ, customization options, sample requests, and export documentation for your target market.
