DEWALT DCS438B: problems, parts and running costs

Checked: 2026-10-11

Summary

The DEWALT DCS438B is a bare-tool 20V MAX XR 3-inch cut-off tool that ships without a battery or charger, so the real cost is the tool plus a 20V MAX XR battery and charger. No independent instrumented test or owner failure data was found, and community evidence is sparse. At $199 (Northern Tool and Home Depot) it is a reasonable buy only for buyers who already own 20V MAX XR batteries.

Common problems and fixes

Bare tool, no battery or charger — the DCS438B ships without a battery or charger; buyers new to the platform must buy both separately, which is a significant extra cost. The DCS438E1 kit variant includes them. [1]
Small grip — ToolGuyd commenters flagged the small grip as a potential issue for users with large hands, based on the tool’s appearance. No measurement or fix was reported. [3]
No independent test — no instrumented test of this exact model was found, so the specifications are manufacturer claims. [3]
The 3-year limited warranty, 1-year free service and 90-day satisfaction guarantee apply. [1]
