AVID POWER Angle Grinder 4-1/Makita 9557NB 4-1/2" Angle Grinder

Overview

When it comes to angle grinders, the AVID POWER Angle Grinder and the Makita 9557NB stand out as popular options. The AVID POWER grinder is priced at $42.99, making it about 49% cheaper than the Makita, which costs $84.01. Both tools are designed for cutting and grinding, but they have distinct features that cater to different user needs. This comparison will help you decide which grinder is the better choice for your projects.

Power and Performance

The AVID POWER Angle Grinder features a powerful 6.5 Amp motor that produces a no-load speed of 11,500 RPM. This makes it suitable for light-duty home projects, allowing users to handle tasks efficiently. In contrast, the Makita 9557NB is equipped with a slightly more powerful 7.5 Amp motor, delivering 11,000 RPM. While the AVID POWER offers a higher speed, the Makita's power-to-weight ratio is impressive, making it easy to handle despite being heavier at 4.5 lbs compared to the AVID POWER's 3.20 lbs.

Design and Comfort

The design of both angle grinders significantly impacts user comfort during prolonged use. The AVID POWER grinder is lightweight at only 3.20 lbs, which can reduce fatigue over time. It also features a 2-position handle suitable for both left- and right-handed users. On the other hand, the Makita 9557NB has a compact design with a 2-1/2 inch diameter barrel, making it easy to grip. Weighing 4.5 lbs, it might be less comfortable for extended use, but its ergonomic design compensates for this, providing a good balance of control and comfort.

Safety Features

Safety is a crucial consideration when using power tools, and both grinders come with features designed to protect users. The AVID POWER Angle Grinder has a screw-on guard that can be adjusted to different angles, preventing potential injuries while working. It also incorporates a lightweight design that reduces fatigue, allowing for safer operation during long tasks. The Makita 9557NB includes a protective zig-zag varnish that seals the armature from dust and debris, enhancing the tool's longevity. Additionally, its labyrinth construction seals and protects the drive gear and bearings, ensuring a longer tool life.

Included Accessories

When purchasing an angle grinder, the included accessories can add significant value. The AVID POWER grinder comes with two cutting wheels and two grinding wheels, making it ready to use right out of the box. This feature provides excellent value for its lower price. In comparison, the Makita 9557NB includes a grinding wheel, wheel guard, lock nut, and side handle, which are essential for immediate use. However, it lacks the additional wheels provided by AVID POWER, which may require further investment for similar functionality.

Durability and Maintenance

Durability is essential for power tools, and both brands have their strengths in this area. The AVID POWER Angle Grinder features a brushed motor, which is generally less durable than the brushless motors often found in higher-end models. However, it does allow for easy replacement of carbon brushes, extending the tool's service life. The Makita 9557NB is designed with an all-ball bearing structure and metal gear housing, making it more robust and capable of withstanding harsher working conditions. Additionally, its protective varnish contributes to its longevity by shielding the motor from dust and debris.

Brand Reputation

Brand reputation can significantly influence purchasing decisions. AVID POWER is known for providing affordable tools that cater to DIY enthusiasts and light-duty users. Its grinder ranks 22,682 in sales, indicating a reasonable level of popularity. Conversely, Makita is a well-established brand in the power tool market, often favored by professionals for its reliability and performance. The Makita 9557NB ranks 74,761 in sales, suggesting that while it may appeal to a niche market, it has a loyal following among serious users.

Which should you buy?

Choosing between the AVID POWER Angle Grinder and the Makita 9557NB ultimately depends on your specific needs and budget. If you are looking for a budget-friendly option with essential features for home projects, the AVID POWER grinder is an excellent choice at $42.99, making it about 49% cheaper than the Makita. However, if you require a more robust tool with a reputation for durability and performance, the Makita 9557NB at $84.01 may be worth the extra investment. Consider your usage frequency, the types of projects you plan to undertake, and whether you prioritize price or performance when making your decision.
