An electric brake stops the blade in about 2 seconds. While some grinders have mechanical brakes that stop a rotating wheel or blade instantly, electric brakes rely on electricity to stop the blade. The electric blade brake has likely been the invisible guardian of many tradesmen.
An electric motor brake is a safety feature incorporated into many modern power tools, such as circular saws, drills, and miter saws. The first use of an electric brake on a tool was that of the miter saw, invented in 1964 by Ed Niehaus, a tool engineer for Rockwell Tools. The way the brake on cordless tools works is slightly different than in corded models; when the switch is released, the motor terminals are shorted together, causing the motor to stop almost instantly by dissipating the rotational energy in the windings.
You may get confused about which electric circular saw with electric brake to buy, given the myriads of brands and models of circular saws today.
