Updated July 2026 — full head-to-head comparison.

Overview of Byczone Cordless Angle Grinder and Makita XAG04Z

The Byczone Cordless Angle Grinder is priced at $39.99, making it significantly more affordable than the Makita XAG04Z, which costs $128.99. This represents a price difference of about 69%. While the Byczone model is marketed for its compatibility with Milwaukee 18V batteries and offers three variable speed settings, the Makita grinder incorporates advanced features such as Automatic Speed Change technology and a more efficient brushless motor.

Design and Ergonomics

In terms of design, the Byczone Cordless Angle Grinder emphasizes user comfort with its ergonomic grip and tool-free disc change system. This design is aimed at enhancing user experience, particularly during long jobs. Conversely, the Makita XAG04Z focuses on performance and durability, featuring a robust structure that is characteristic of the Makita brand. The ergonomics of both tools cater to different user preferences, with Byczone leaning towards comfort and Makita prioritizing professional-grade efficiency.

Motor Performance

The Byczone grinder boasts a brushless motor capable of reaching a maximum speed of 8500 RPM, which provides efficient cutting and grinding capabilities. This power is complemented by three adjustable speed settings, allowing for versatility across various materials. In contrast, the Makita XAG04Z features a BL Brushless Motor that optimizes battery energy use for up to 50% longer runtime. The Makita model’s Automatic Speed Change technology dynamically adjusts speed and torque for optimal performance, making it a highly efficient tool for demanding tasks.

Battery Compatibility

Battery compatibility is a significant differentiator between the two models. The Byczone Cordless Angle Grinder is designed to work with Milwaukee 18V batteries, giving it a clear advantage for users who already own Milwaukee tools. However, it does not come with a battery, which may be a downside for some buyers. On the other hand, the Makita XAG04Z is compatible with Makita's extensive range of 18V Lithium-Ion batteries, recognized for their fast charge times. This compatibility allows for greater flexibility and convenience for users invested in the Makita ecosystem.

Application Versatility

When it comes to application versatility, both tools excel but in different ways. The Byczone grinder is ideal for cutting, grinding, and polishing materials, making it suitable for a range of DIY tasks. It has a 4-1/2 inch disc capacity, which is adequate for many home projects. The Makita XAG04Z, however, is designed for more demanding applications, including grinding, cutting, and sanding a broader array of materials such as tile and concrete. Its advanced features position it as a tool better suited for professional environments.

Runtime and Efficiency

The Byczone grinder’s brushless motor provides solid performance, but its runtime will depend heavily on the battery used, which is not included with the purchase. Users must factor in the additional costs of acquiring a compatible battery. In contrast, the Makita XAG04Z benefits from its efficient BL Brushless Motor, which is designed to extend battery life significantly. This efficiency is particularly advantageous for long projects where tool downtime for battery recharges can be a concern.

Pricing and Value

At $39.99, the Byczone Cordless Angle Grinder is about 69% cheaper than the Makita XAG04Z, priced at $128.99. While the lower price may attract budget-conscious consumers, it’s important to consider what each product offers in terms of features and performance. The Makita grinder, despite its higher price, provides cutting-edge technology and a more robust performance, which may justify the investment for serious users. In this regard, the value proposition of each tool varies greatly depending on the user's specific needs.

Which should you buy?

Choosing between the Byczone Cordless Angle Grinder and the Makita XAG04Z ultimately depends on your specific requirements. If you are a casual DIYer looking for an affordable and versatile tool for lighter tasks, the Byczone model offers excellent value at a lower price point. However, if you are a professional or require a tool for more demanding applications, the advanced features and durability of the Makita XAG04Z may be worth the investment. Consider your current tool ecosystem, the types of projects you'll tackle, and how much you're willing to spend to make the best choice for your needs.
