Hilti AG 125 5" Angle Grinder (Corded/230v)
The Compact Powerhouse for Precision and Everyday Use
The Hilti AG 125 (often seen in the 13S or 19SE variants) is the professional standard for a 5-inch (125mm) angle grinder. While its 9-inch big brother is for heavy demolition, the AG 125 is designed for agility, overhead work, and high-precision tasks. It balances a high-performance motor (up to 1900W on some models) with a lightweight frame, making it the most versatile tool in a metalworker's or mason's kit.
Equipped with Hilti’s signature safety and performance electronics, it ensures that even in tight spaces, you have maximum control without sacrificing cutting speed.
Features
- Advanced Safety Suite: Includes Active Torque Control (ATC) to prevent the tool from spinning if the disc snags, and a rapid Electronic Brake that stops the disc in seconds.
- Hilti Smart Power: An intelligent system that regulates motor output to maintain constant speed even when you apply pressure, preventing the tool from stalling or overheating.
- Variable Speed Control (SE Models): Allows you to adjust the RPM (typically from 2,800 to 11,500) to suit different materials, such as lowering the heat for stainless steel or plastic.
- Superior Ergonomics: Features a slim-grip body and a vibration-absorbing side handle, designed specifically to reduce hand fatigue during extended "all-day" use.
- Dust Extraction Ready: Compatible with Hilti’s clip-on dust hoods, turning it into a clean-running tool for indoor masonry or renovation work.
- Exceptional Durability: Built with long-lasting carbon brushes and a robust cooling system to withstand the fine grit of concrete and metal dust.
Applications
The AG 125 is the "Swiss Army Knife" of grinders, perfect for:
- Metal Finishing: Deburring, grinding down welds, and polishing steel or stainless steel surfaces to a smooth finish.
- Precision Cutting: Slicing through rebar, threaded rods, metal pipes, and thin sheet metal with minimal effort.
- Masonry & Tile Work: Accurate cutting and shaping of bricks, natural stone, and ceramic tiles when used with a diamond blade.
- Joint Restoration: Removing old mortar or cleaning out expansion joints in brickwork (often paired with a "tuck-pointing" or chasing hood).
- Coating Removal: Using wire cups or diamond grinding heads to strip rust, paint, or old adhesive from concrete and metal.
- Indoor Renovations: Ideal for work in occupied buildings where its compact size and dust-collection capabilities are essential.
Pro Tip: For the best results on stainless steel, use the AG 125-19SE on a lower speed setting to avoid "blueing" (heat discoloration) of the metal.
