Whatever it is used for, an angle grinder is a highly versatile tool that is vital for any site worker or tradesperson’s toolkit. The Makita DGA504 125mm 18v Angle Grinder is the perfect choice, as it includes everything you need in a grinder. Constant speed under load automatically changes the cutting speed according to load condition, enhancing your performance. The Makita Angle Grinder is equipped with a highly powerful motor that delivers a no load speed of up to 8,500rpm, and has self-adjusting torque that alters depending on the product you are cutting; so softer materials will produce a slower, more controlled speed that reduces kickback and friction. Anti-restart prevents the machine from accidental start-up in order to ensure safe use, while a soft start function allows the cordless Angle Grinder to start up gradually rather than at full speed. Battery fuel gauge LED’s make it clear when you need to charge up the grinder tool, and LED’s light up to show you when the anti-restart function and current limiter have been activated, too. A rubberised soft grip means the electric angle grinder is comfortable to hold and won’t give you any wrist strain when using for long sessions. Also featuring a slide switch for one-handed operation, Extreme Protection Technology (XPT) for outdoor use or harsh environments, and an innovative electric brake. This is a bare unit, meaning it does not include a battery or charger.
This guide is for anyone using the Makita DGA504Z 18V Angle Grinder, a versatile tool for cutting, grinding, and polishing. It offers powerful performance with its brushless motor, constant speed control, and safety features. While it provides excellent performance, remember that this is a bare unit and requires a battery and charger. This guide will help you understand the features, use the grinder effectively, and troubleshoot common issues.
