HILTI 5" CORDLESS GRINDER

Hilti AG 4S-22 Cordless Angle Grinder 4.5"

The Hilti AG 4S-22 is a compact, high-performance cordless angle grinder engineered for precise metalworking, surface finishing, and material cutting. Powered by Hilti’s Nuron 22V battery platform, it delivers up to 10% faster cutting speeds and extended runtime compared to previous-generation 22V grinders—bringing corded-like output to tight, awkward jobsites without the restriction of power cords.

Designed specifically with a variable 6-speed dial, the AG 4S-22 provides complete control when working across heat-sensitive materials like stainless steel, as well as everyday structural metal and masonry.

Features

• 6-Stage Variable Speed Control: Dial settings ranging from $3,400$ to $7,600\text{ RPM}$ allow precise speed matching for delicate polishing, stainless steel finishing, or aggressive heavy stock removal without burning the workpiece.
• Active Torque Control (ATC): Automatically shuts off the motor in milliseconds if the disc binds or jams, protecting the operator from dangerous tool kickback.
• Slimline Ergonomic Design: Contoured, slim grip body and lock-on switch reduce hand strain during continuous overhead or restricted-space grinding.
• Brushless Motor Technology: Eliminates carbon brush maintenance and delivers up to three times longer motor lifespan while optimizing battery energy draw.
• Tool-Free Guard & Quick Adjustments: Allows fast, easy repositioning of the protective guard to shield the operator from flying sparks and debris.
• Nuron Battery Intelligence: Onboard battery health monitoring and cloud-connected diagnostics optimize fleet usage and performance.

Applications

• Metal Cutting & Slitting: Slicing rebar, steel struts, threaded rod, sheet metal, and structural pipes.
• Stainless Steel & Specialty Metals: Low-speed grinding, weld prep, deburring, and surface finishing on heat-sensitive alloys without discoloration.
• Masonry & Tile Cutting: Precise cutting of ceramic tiles, porcelain, brick, and small concrete blocks using continuous-rim diamond blades.
• Surface Prep & Cleaning: Rust removal, beveling, paint stripping, and flash deburring using flap discs or wire wheel accessories.
