Best Circular Saws

A circular saw is an essential tool for any serious DIYer or professional carpenter. It can cut through wood, metal, plastic, and masonry with ease. Here’s a comprehensive guide to understanding and selecting the best circular saw for your needs.

Types of Circular Saws

There are three main types of circular saws: sidewinder, worm drive, and hypoid.

• Sidewinder: The most common type, also known as a direct drive saw. Light and compact. The motor sits next to the blade.
• Worm Drive: Has a motor positioned at the back. Provides more torque, ideal for heavy-duty tasks.
• Hypoid: Similar to worm drive but with a different gearing mechanism. Usually quieter and requires less maintenance.

Key Features to Consider

When choosing a circular saw, consider the following features.

Blade Size

The most popular blade size is 7-1/4 inches. It offers a good balance between cutting depth and versatility. For lighter projects, a smaller blade may suffice.

Power

Measured in amps, power determines how easily the saw can cut through tough materials. For most DIY projects, a 15-amp motor is ideal.

Bevel Capacity

Allows the saw to make angled cuts. A higher bevel capacity gives more flexibility for various cutting tasks.

Safety Features

Look for saws with electric brakes, blade guards, and safety lock features to prevent accidents.
