TEENO Cordless 3-Inch Angle Grinder Kit — 19,500 RPM, 2×16.8V 2000mAh Batteries & 6 Discs

TEENO's cordless 3-inch angle grinder is a compact, high-speed handheld kit that delivers 19,500 RPM cutting and grinding power with two swap-ready 16.8V batteries for uninterrupted DIY work.

This all-in-one mini grinder is built for homeowners and hobbyists who need a portable, lightweight tool that can cut, sand, and shape small projects without the hassle of cords. The kit includes two 2000mAh batteries, a fast charger, six accessory discs, gloves, and a storage case so you can begin projects immediately. Ergonomic design, a spindle lock for quick disc changes, and a dual-action safety start make it suitable for indoor repairs, garage tasks, and light renovation jobs.

How much cutting and grinding can this mini grinder handle?

The TEENO cordless grinder is optimized for light to medium-duty tasks—thin metal, small tile work, soft wood and surface rust removal. Its 3-inch discs and 19,500 RPM motor let you make precise shallow cuts and finish surfaces quickly.

• Maximum cutting depth roughly 1/2 inch for thin materials
• Includes metal, flap, HSS, and diamond discs for varied materials
• High-speed 19,500 RPM motor for clean, fast cuts and smoothing

How long will the batteries last and can you keep working continuously?

The kit ships with two removable 16.8V 2000mAh batteries so you can run one while the other charges, minimizing downtime. Battery life will vary with load; light sanding and trimming will last longer than continuous cutting of metal.

• 2× 16.8V 2000mAh batteries for swap-and-go use
• Fast charger included to reduce recharge time
• Smart dual-battery setup preserves workflow during longer jobs

Is the tool comfortable and safe for occasional users?

TEENO designed this model to be lightweight and easy to handle for one-handed operation, reducing fatigue during repetitive tasks. Safety features like a two-button start and an adjustable protective guard help prevent accidental starts and deflect debris away from the user.

• Ergonomic anti-slip rubberized grip for secure control
• Dual-action lock requires two inputs to power on
• 90° adjustable guard helps redirect sparks and fragments

What comes in the kit and how quickly can I start working?

The TEENO grinder kit arrives ready for immediate use with a carefully chosen set of accessories for common home tasks. A wrench and spindle lock make swapping discs fast, and the included case keeps everything organized for transport or storage.

• TEENO angle grinder, 2× batteries, and fast charger
• 6 accessory discs: metal, flap, HSS, and diamond varieties
• Wrench, spindle lock, protective gloves, and storage case

Who is this for? If you’re a DIY homeowner, renter, or hobbyist who needs a portable, user-friendly tool for quick repairs, small renovations, or craft projects, the TEENO cordless angle grinder is built to simplify those tasks. It’s particularly useful when you need cordless convenience, quick accessory changes, and a compact design for confined spaces like under sinks, inside cabinets, or on scaffolding. This kit is intended for light to moderate jobs—not heavy industrial cutting—and is a practical second tool for any workshop or home toolbox.
