FEIN 99100000834 Corded Angle Grinder 125 mm 1700 W with KickBack Stop and Soft Start

On a busy metal fabrication floor, a welder reaches for the FEIN 99100000834 to smooth a fresh weld bead. The 1700 W motor spins the 125 mm disc to 11,000 RPM, slicing through steel with controlled aggression. Its KickBack Stop engages instantly if the wheel jams, preventing dangerous torque reaction. Soft Start brings the disc up to speed smoothly, protecting both the operator and the gearbox. This angle grinder is built for continuous industrial use where safety and reliability are non-negotiable.

Key specifications

• Power input: 1700 W, output: 1000 W
• Disc diameter: 125 mm with M14 spindle thread
• No-load speed: 11,000 RPM
• Tool-free adjustable guard with anti-twist design
• Quick-clamping nut for fast disc changes
• 4 m cable for extended reach
• Vibration level (grinding): 6.5 m/s²
• Sealed electronics and motor for dust protection

Why choose it

The FEIN POWERtronic motor delivers constant speed under load, so the disc doesn't bog down when you bear into the workpiece. Restart protection and self-start lock prevent accidental startups after power interruptions. Electronic overload protection extends tool life by cutting power before the motor overheats. The anti-twist guard adjusts without tools, making it easy to reposition for cutting or grinding. Weighing in at a balanced 2.5 kg, it reduces fatigue during overhead work.

Ideal use cases

• Weld seam removal and surface preparation in metalworking shops
• Cutting rebar, pipe, and sheet metal on construction sites
• Grinding concrete edges and removing formwork residue
• Automotive body repair and rust removal
• Fabrication of stainless steel railings and structures

Good to know

The 125 mm disc size is the industry standard for portable angle grinders, offering a good balance between cutting depth (up to 34 mm) and maneuverability. The 4 m cable gives you freedom to move around a workbench without an extension cord. FEIN's sealed electronics keep conductive dust out of the motor and switches, a common failure point in harsh environments. For maximum safety, always use the side handle and wear appropriate PPE. The tool is compatible with standard 125 mm discs with a 22.23 mm bore.
