Question 1

What is the Makita DGA455Z 115mm 18V cordless angle grinder and what can it do?

Accepted Answer

The Makita DGA455Z is a cordless angle grinder powered by an 18V Li‑Ion battery with a brushless motor, delivering strong cutting and grinding performance comparable to corded models. It uses a 115mm disc, has a soft start, anti‑restart, LED light, dust extraction, spindle lock, and adjustable side handle for control. It automatically adjusts speed under load for efficient operation.

Question 2

What are the key specifications and features of the DGA455Z?

Accepted Answer

Brushless motor for efficiency and longer life; no‑load speed around 5700 RPM; 115mm disc diameter; adjustable side handle; two‑finger trigger; anti‑restart; soft start; built‑in dust extraction; spindle lock; built‑in LED light; battery fuel gauge; compatible with Makita 18V Li‑ion batteries.

Question 3

How does the brushless motor benefit me compared with a brushed grinder?

Accepted Answer

A brushless motor delivers higher efficiency, more power for the same battery, cooler operation under load, reduced wear, and longer tool life, meaning you can cut and grind longer between charges and with less maintenance.

Question 4

What safety features does the DGA455Z include and how should I use them?

Accepted Answer

It includes anti‑restart to prevent accidental starts, soft start to reduce shock on startup, a two‑finger trigger for better control, an adjustable side handle, and an integrated guard. Always wear eye protection, hearing protection, gloves, and a face shield when grinding, and ensure the guard is properly installed.

Question 5

How does the built‑in dust extraction system work and how do I use it?

Accepted Answer

The integrated dust extraction helps keep your work area cleaner and improves visibility by pulling dust away from the wheel. Use compatible dust collection accessories and ensure the nozzle or guard is connected properly to your vacuum or collection system for best results.

Question 6

How do I change discs on the DGA455Z?

Accepted Answer

Use the spindle lock to immobilize the spindle, then loosen the clamp nut or screw to remove the old disc and install a new 115mm disc. Re-tighten securely and ensure the disc speed is appropriate for the task.

Question 7

What are good use cases for this grinder?

Accepted Answer

Metal fabrication tasks such as beveling, deburring, edge grinding, weld seam grinding, and cutting tasks on steel/aluminum; its cordless design is ideal for sites without easy mains power and for overhead or tight spots where a corded grinder would be unwieldy.

Question 8

How do I install and operate the DGA455Z with batteries?

Accepted Answer

Insert a compatible Makita 18V Li‑Ion battery into the tool, attach a suitable 115mm wheel and guard, connect any dust collection accessory if used, then switch on with the safe two‑finger trigger. Start with a light load to reduce startup shock.

Question 9

What accessories are compatible and recommended for this grinder?

Accepted Answer

Standard 115mm grinding and cutting discs, wheel guards, carbon brushes (as needed for maintenance), dust extraction accessories, and Makita‑authored battery packs and chargers compatible with 18V LXT systems.

Yes. You can compare Makita models such as DGA510Z (125mm) and DGA452Z (115mm) on Fepy here: https://fepy.com/product/makita-dga510z-125mm-18v-cordless-angle-grinder and https://fepy.com/product/makita-dga452z-115mm-18v-cordless-angle-grinder.

Question 12

What should I consider when deciding between a cordless and corded grinder for my project?

Accepted Answer

Consider the need for portability, access to power outlets, and runtime on a single battery. Cordless 18V grinders offer freedom to work anywhere, with the trade‑off of battery life and weight. If you have a constant power source and long continuous use, a corded model may be more economical for extended sessions.

Question 13

What maintenance and safety practices help prolong the tool life?

Accepted Answer

Keep the tool clean and free of dust; use correct discs; perform occasional lubrication if recommended by Makita; regularly inspect the battery and replace worn brushes or worn components; store in a dry place; always follow PPE guidelines and manufacturer instructions.
