Bclythax Cordless Angle Grinder, 4-1/2-inch, 6-Speed with LED Display
Product description
The brushless motor delivers up to 9000 RPM for metal cutting, grinding, rust removal and weld cleanup, while six speed settings let you tailor the tool to the task. Its cordless design works with compatible DeWalt 20V Max batteries, making it a practical addition to a battery platform you already use.
An LED display shows tool status, and electronic anti-kickback protection cuts motor power when it detects a sudden wheel jam or change in rotation.
Practical tips
Choose a speed to suit the material and finish you need. Lower settings are intended for metal polishing, the middle range for weld grinding, and higher settings for rebar cutting. Auto Mode adjusts output based on workload, offering another way to manage cutting, grinding, polishing and finishing tasks.
For example, a workshop job involving weld cleanup and surface preparation can make use of the grinder’s adjustable speeds and brushless motor. If you need a cordless tool that can move between work areas, this battery-powered format offers a different approach from setting up a grinder at a fixed workstation. The side handle can be mounted on either side to support handling and control from your preferred position.
What stands out
The 4-1/2-inch grinder is designed for metal processing, including cutting rebar, bolts and steel edges, grinding weld seams and rough edges, and removing rust or paint. Flap discs also support polishing and finishing work. A smart memory function recalls the last speed setting, so you can return to your preferred setup more easily between tasks.
The included accessory kit contains two cutting wheels, two grinding wheels and two flap discs, along with a guard and wrench. The grinder uses a standard 5/8\"-11 spindle. To change a disc, remove the battery first, then use the spindle lock and outer flange to remove and secure the wheel.
