When comparing the Bosch GWS8-45 and the Makita 9557NB, the Bosch model is priced at $79.00, making it about 17% cheaper than the Makita, which is priced at $84.01. Both angle grinders feature a powerful 7.5 amp motor capable of delivering 11,000 RPM, making them well-suited for a variety of grinding tasks. However, the Bosch GWS8-45 holds a better sales rank at 30,612, while the Makita 9557NB sits at 74,761, indicating it is a more popular choice among users.

Power and Performance

Both the Bosch GWS8-45 and Makita 9557NB are equipped with a robust 7.5 amp motor that provides high output power. The performance specifications are nearly identical, with both tools offering a no-load speed of 11,000 RPM. This makes them suitable for heavy-duty grinding tasks. However, the Bosch grinder's directed airflow feature helps divert dust away from vital components, potentially enhancing its durability over time. In contrast, the Makita grinder includes a protective zig-zag varnish that seals the armature from dust and debris, which also contributes to its longevity.

Design and Comfort

In terms of design, the Bosch GWS8-45 has a slim-grip design that enhances user comfort for extended periods of use. Weighing only 4.2 lbs, it is slightly lighter than the Makita 9557NB, which weighs 4.5 lbs. The Bosch model also features a two-position side handle that allows for greater control during operation. On the other hand, the Makita 9557NB boasts a compact design with a small 2-1/2 inch diameter barrel, which may appeal to users looking for a more manageable grip. Both grinders are designed for comfort, but the Bosch may have a slight edge due to its lighter weight.

Durability Features

Durability is a significant consideration for angle grinders, and both models offer features that enhance their longevity. The Bosch GWS8-45 includes durable carbon brushes that contribute to an extended tool life, along with a Service Minder brush system that alerts users when maintenance is needed. The Makita 9557NB also emphasizes durability with its labyrinth construction that seals and protects the drive gear and bearings from contamination. While both grinders are designed for long-term use, the Bosch's Service Minder feature adds an extra layer of convenience for users who may not be proactive about maintenance.

Safety Features

Safety features are essential in power tools, and both the Bosch GWS8-45 and Makita 9557NB prioritize user protection. The Bosch grinder includes a burst-protection guard that allows for quick adjustments, enhancing user security during operation. The Makita model features an AC/DC switch, enabling it to be used with alternative power sources, which can be a significant advantage in various working environments. Both tools provide sufficient safety measures, but the Bosch model's focus on the quick-adjust guard may offer added peace of mind for users.

Included Accessories

Both angle grinders come with essential accessories, but the Makita 9557NB offers a more comprehensive kit. It includes a 4-1/2 inch grinding wheel, wheel guard, lock nut, lock nut wrench, side handle, and inner flange. In contrast, while the Bosch GWS8-45 does not specify included accessories in the product description, it is known for its ease of disc changes thanks to a large spindle lock feature. Users looking for a complete package may find more value in the Makita's included accessories, as they provide everything needed to get started with grinding tasks.

Price Comparison

The Bosch GWS8-45 is available for $79.00, making it a more budget-friendly option compared to the Makita 9557NB, which costs $84.01. This price difference of about $5.01 can be a deciding factor for consumers who are looking for quality at a lower cost. Additionally, the Bosch model has a lower average price over the past 90 days at $70.80, suggesting that it may be available at an even better value if you can catch it during a sale. For those prioritizing cost without sacrificing performance, the Bosch GWS8-45 offers a compelling choice.

Which should you buy?

Choosing between the Bosch GWS8-45 and the Makita 9557NB ultimately comes down to your specific needs and preferences. If you prioritize a lighter tool with a slim grip and excellent dust management, the Bosch GWS8-45 is the better option, especially given its lower price and better sales rank. However, if you want a more comprehensive accessory package and appreciate the AC/DC switch feature for versatility, the Makita 9557NB may be worth the additional cost. Both models are high-performing grinders, but the Bosch GWS8-45 edges out in terms of comfort, price, and popularity.
