Makita DGA454RTJ 18V LXT 115mm Cordless Angle Grinder

Key specs include: 8,500 RPM top speed, 115mm disc diameter, 2.1 kg weight (tool only), 18V Li‑ion battery compatibility, soft-start, anti-restart protection, LED battery indicator, tool-less wheel cover, and a dust-resistant motor for longevity.

Yes. It runs on Makita 18V LXT batteries, so it’s compatible with the broader Makita 18V LXT system, allowing you to mix and match batteries across compatible tools. The LED battery indicator helps you monitor charge levels during use.

It features an ergonomic soft-grip handle and a balanced, compact body (about 2.1 kg), which helps reduce fatigue and improve control during extended use.

Safety features include anti-restart protection to prevent accidental starts, a soft-start mechanism to minimize torque kick, and a dust-resistant motor designed for harsher work environments.

Ensure the guard is correctly mounted, attach the 115mm wheel, and secure it with the tool-less wheel cover. Install a charged 18V LXT battery, power on, and use the trigger to start grinding or cutting. The soft-start helps reduce sudden torque at startup.

It’s versatile for metalworking and surface finishing, including grinding, cutting, beveling, and deburring of metal and stone where a compact, cordless grinder is advantageous.

Keep vents clean and free of dust, store the battery in a cool, dry place, and charge as needed. Periodically inspect the wheel guard and spindle area for wear and ensure the battery contacts are clean before recharging.

Both are 115mm cordless grinders, but DGA454RTJ is designed as a newer 18V LXT model with features like LED battery indication and enhanced dust resistance, while DGA452RTJ is an earlier 115mm cordless option.

DGA511 uses a 125mm wheel size (larger disc) and differs in RPM range and balance due to the larger wheel. If you need a larger-cutting capacity, this is a relevant alternative. See: https://fepy.com/product/makita-dga511-18v-lxt-125mm-cordless-angle-grinder

The model features a dust-resistant motor and is designed for tough environments. Some users pair it with compatible dust extraction accessories; check the specific Fepy listing for compatibility with dust ports or vacuum attachments.
