§ FAQ

What collet sizes does the DWE4887 accept?

The DWE4887 accepts both 1/4-in. and 1/8-in. collets, making it compatible with a wider range of die grinder accessories than models that only accept 1/4-in. shank bits.

Does the DWE4887 have a lock-on switch?

Yes. The DWE4887 features a paddle switch with a lock-on button, allowing sustained no-hands-needed operation during extended grinding or finishing tasks. The DWE4887N is the no-lock-on version.

What is the no-load speed of the DWE4887?

The DWE4887 delivers 25,000 RPM under no-load conditions, which is standard for corded straight die grinders and appropriate for carbide burr work, mounted abrasive stones, and small grinding wheels.

What is the difference between the DWE4887 and DWE4887N?

The DWE4887 includes a lock-on button for sustained operation. The DWE4887N is the no-lock-on variant, which is required by OSHA and certain industrial safety programs. Both use the same 4.2 Amp motor and 25,000 RPM rating.

What applications is the DWE4887 suited for?

The DWE4887 is suitable for precision metalworking applications including carbide burr grinding, deburring castings, weld cleanup in tight areas, die and mold polishing, and mounting point abrasive work.
