Angle grinder 4.5"

Start by deciding between corded and cordless options. Look for a 115 mm (4.5 inch) disc as the standard size across models, with a spindle thread of M14 and no‑load speeds around 11,800–12,000 rpm. Power ranges from 710 W to 960 W for reliable everyday grinding and cutting, while cordless variants exist for mobility, with kits delivering up to 1280 W equivalent on 42V systems. Some packs ship without a disc, so you may need to buy discs separately. A supplied auxiliary handle improves control during tougher work.

Power source and battery compatibility is the most complex attribute because it combines mobility, runtime, and ecosystem compatibility. Corded models provide constant power suitable for heavy tasks, whereas cordless options rely on voltage (42V or 20V) and battery capacity (for example 2×2.5Ah or 2×4.0Ah). Some TOTAL cordless kits include two batteries and a fast charger, and others are tied to a specific platform. Always verify that the battery system you choose will work with your existing tools and intended tasks.

DIY users performing occasional home repairs typically benefit from a corded model around 710–960 W for steady, cost‑effective performance. Professionals or site workers needing mobility and longer runtimes should favor cordless kits, such as 42V models delivering up to 1280 W with two batteries, or a 20V brushless kit offering strong torque. Consider your typical tasks, power access, and whether you’ll move between jobs often. Pick a tool that balances budget, weight, and the amount of grinding or cutting you expect to do.

Keep safety and performance top of mind by verifying disc size, spindle thread, and accessory fit. Use 115 mm (4.5 inch) discs with an M14 spindle and check whether the disc is included in your pack or must be purchased separately. Regularly clean vents and guards to prevent overheating, and use the provided auxiliary handle to reduce kickback during heavy grinding. For cordless models, use the recommended battery platform and charger to preserve power and runtime. Store the tool unplugged or with batteries removed when not in use.

Yes, cordless options are available in 42V and 20V ecosystems. A 42V TOTAL kit can deliver up to 1280 W with two batteries (e.g., 2×2.5Ah) and a fast charger, while another 42V kit may offer 1080 W with two 2.0Ah cells. A 20V TOTAL cordless kit provides about 900 W with two 4.0Ah batteries and a fast charger. Batteries are not interchangeable between platforms, so choose the kit that aligns with your other tools. Always use the included charger for optimal performance and longevity.

The 4.5-inch (115 mm) grinder excels at metal cutting, weld grinding, masonry work, and general construction tasks. Use discs compatible with 115 mm diameter and M14 threading, selecting metal grinding discs for metalwork and masonry discs for stone or brick. The compact size offers precise control, especially when working in tight spaces. An ergonomic grip and an included auxiliary handle improve handling during prolonged sessions. Always pair the grinder with the appropriate disc type and maintain a steady stance to ensure clean cuts and safe operation.
