Critical Warning: Why You Should Never Oil Your DeWalt Brushless Nail Gun
Dublin, Ireland – A recent online video by Irish tool enthusiast Dean Doherty has shed light on a critical, yet often overlooked, maintenance detail for DeWalt’s 18V brushless nail guns. Doherty, known for his tool teardowns, demonstrated that these popular power tools operate on a unique friction-driven flywheel system, a significant departure from traditional pneumatic nailers that require regular oiling. During his detailed disassembly, Doherty revealed how oil, if applied to these specific DeWalt models, can severely impair their functionality. “They work using friction, no friction, no good,” Doherty explained, pointing to visible oil residue on the internal flywheel and ram components of a malfunctioning unit. He stressed that this lubrication, intended to help other tools, actually degrades the performance of DeWalt’s brushless nail guns by eliminating the necessary friction for operation. According to Doherty, once oil contaminates these internal parts, the damage is often irreversible. Even replacing components may not fully restore the tool’s ability to drive nails effectively. This insight serves as a vital warning for users, potentially saving them from costly repairs or premature tool replacement by highlighting the importance of understanding specific tool mechanisms before applying general maintenance practices.
