DEWALT® Launches New Small Angle Grinders with Improved Brake and Lanyard Ready™ Connection

Press Release   •   Jan 13, 2016 09:00 EST

TOWSON, MD (January 13, 2016) –DEWALT announces the launch of its new 4 ½” Small Angle Grinders with brake (DWE4222N*, DWE4222, DWE4224), ideal for professionals who need to perform a variety of applications in tight spaces such as grinding and beveling steel, grinding welds, cutting pipe and steel plate and concrete surface prep. The new grinders feature a Lanyard Ready™ Connection, which allows users to utilize a lanyard to tether the grinder to rigid structures at jobsites, and brake that stops the wheel 50% faster on average than DWE402 model with DW4541 abrasive wheel.

“The new 4 ½” Small Angle Grinders raise the bar for the compact small angle grinder with improvements in the key focus areas durability, performance, ergonomics, and ease of use, compared to the DEWALT Small Angle Grinder D28402 and D28402N that the DWE4222/N and DWE4224 are replacing,” said Sean Kelly, Group Product Manager.

Key improvements include the Lanyard Ready™ Connection, improved brake system, a Dust Ejection System™ that has been taken to a new level of design and functionality, an E-CLUTCH™ that activates in less than a tenth of a second when a wheel pinch/stall event is detected, and the new motor design. A new motor platform has been developed yielding 40% more copper than the motor on the D28402, upgrading the grinder to 11 Amps and adding another 200 max watts of output power. Average temp rises have also been reduced compared to the D28402 and the body circumference is still smaller than competitors’ models**.

Durability and long tool life are the top concerns of professionals who use grinders. A detriment to grinders is abrasion from debris and particulates that are ingested into the grinder while in use, when the grinder pulls air through the motor to cool. The new 4 ½” Small Angle Grinders feature a newly redesigned and patented Dust Ejection System™. This feature filters debris from the air allowing mostly clean air to pass across the motor leading to long motor life.

First introduced on the D28402 Small Angle Grinder, DEWALT’S patented Dust Ejection System™ feature required power from the motor to operate. The new design of the Dust Ejection System™ on the DWE402 does not require power from the motor. This allows the motor to be protected without compromising performance.

For most grinding applications, performance is critical. Power is needed to not only complete applications quickly but complete them for long periods without overheating the grinder. In 2005, when DEWALT launched the D28402 Small Angle Grinder as a next generation motor Phase 1 with a patented 4 piece field design, the extra copper allowed the motor to stay small and compact but generate high power. With the new Small Angle Grinders, DEWALT is introducing phase 2 of the Next Generation Motor. The new motor has the 4-piece field introduced in phase 1 plus 40% more copper now added to the armature providing even more power.

“The new 4 ½” Small Angle Grinders deliver the durability and performance users need, but what makes DEWALT different with these new small angle grinders is that we refused to trade off ergonomics in two ways,” said Kelly. “The 194mm body circumference remains smaller than competitive models**. Additionally, the new motor design along with the total system approach to increasing efficiency, the new grinders have a 35% cooler average temp rise on the gear case and a 30% cooler average temp rise on the field case (body of the grinder) compared to previous DEWALT models (D28402 and D28402N).

The new grinders are also designed to be easier to use. A patent pending feature, the One-Touch™ guard allows for the guard to be adjusted in a single, fluid motion. Keyless guards and detent style guards found on competitive units require 2 or more actions to adjust the guard. At 4.6 lbs and a circumference of 194mm, the slim, ergonomic body design allows for comfortable use without sacrificing the performance that users want and need to perform tough cutting and grinding applications.

The DWE4222, DWE4222N, and DWE4224 are expected to retail for approximately $159 and will be available wherever DEWALT products are sold. The tool will come standard with a three-year limited warranty, one-year free service contract and 90-day money-back guarantee.
