AVID POWER Angle Grinder, 7.5-Amp 4-1/Makita 9557NB 4-1/2" Angle Grinder

Price Comparison

The AVID POWER Angle Grinder is priced at $42.99, making it about 17% cheaper than the Makita 9557NB, which retails for $84.01. This significant price difference may appeal to budget-conscious consumers or those who need a grinder for light to medium tasks without making a heavy financial commitment. The AVID POWER model offers a good combination of features for its price, making it a compelling option for DIY enthusiasts. On the other hand, the Makita 9557NB is priced higher but is known for its durability and advanced features, which might justify the additional cost for professional users or more intensive applications.

Motor Power and Performance

Both the AVID POWER Angle Grinder and the Makita 9557NB are equipped with a 7.5 AMP motor, but their RPM ratings differ. The AVID POWER grinder can reach up to 12,000 RPM, while the Makita tops out at 11,000 RPM. This means that the AVID POWER model offers a higher output speed, potentially allowing for faster cutting and grinding tasks. However, the Makita's robust construction and protective features, such as protective varnish and labyrinth seals, may provide longer tool life, making it a better option for heavy-duty users.

Design and Ergonomics

In terms of design, the AVID POWER Angle Grinder weighs 3.64 lbs, making it lightweight and easier to handle for extended periods. This can reduce user fatigue during longer projects. The Makita 9557NB, while slightly heavier at 4.5 lbs, features a compact design with a small 2-1/2" diameter barrel, which may offer superior comfort for some users. Both grinders come with an adjustable safety guard, but the AVID POWER's tool-free adjustment could be more convenient for quick changes. Ergonomics play a vital role in user experience, and while both models are designed for comfort, personal preference will ultimately dictate which feels better in hand.

Versatility and Applications

The AVID POWER Angle Grinder is marketed as versatile, capable of handling various tasks from metal cutting to masonry work. It includes accessories such as two metal cutting wheels and a flap disc, making it ready to use out of the box. In contrast, the Makita 9557NB is primarily designed for high-output power and features protective elements to prolong tool life, although it does not come with as many accessories. The versatility of the AVID POWER may appeal to DIYers who want a multi-functional tool for their home projects, while professionals may prefer the reliability and performance of the Makita for more demanding applications.

Durability and Build Quality

Durability is a crucial factor when choosing an angle grinder. The Makita 9557NB boasts features such as labyrinth construction that seals the motor and bearings from dust and debris, which is essential for prolonged tool life. Additionally, the protective varnish helps to keep the armature clean. While the AVID POWER grinder is also built for longevity, its durability features are not as emphasized as those found in the Makita. Users who plan to use their grinder in tough environments might find the Makita's extra protective measures more reassuring, despite its higher price.

Safety Features

Both the AVID POWER Angle Grinder and the Makita 9557NB come with safety features designed to enhance user protection. The AVID POWER model includes a tool-free adjustable safety guard that can be positioned quickly to deflect sparks and debris effectively. It also features a two-position side handle for added control. The Makita model includes a lock-on/off feature and protective varnish to keep internal components safe from dust. While both grinders prioritize safety, the specific features may appeal differently to users based on their individual needs and preferences during operation.

Accessories and Included Items

The AVID POWER Angle Grinder comes with a good selection of accessories right out of the box, including grinding wheels, a flap disc, and an auxiliary handle. This can save time and additional costs for users who want to start using their grinder immediately. Conversely, the Makita 9557NB includes a grinding wheel and side handle but does not come with as many accessories. For those who value getting a complete package, the AVID POWER may have the edge. However, professionals may prefer the quality and reliability of the Makita’s included items, even if they are fewer in number.

Which should you buy?

Choosing between the AVID POWER Angle Grinder and the Makita 9557NB ultimately depends on your individual needs and budget. If you are a DIY enthusiast or someone who occasionally uses an angle grinder for lighter tasks, the AVID POWER model offers excellent value at $42.99 with a higher RPM and a variety of included accessories. On the other hand, if you are a professional or plan to use the grinder frequently for more demanding tasks, the Makita 9557NB's durability, lower RPM, and excellent protective features may justify its higher price of $84.01. Both tools have their strengths, so consider what aspects are most important for your projects before making a decision.
