DEWALT Grease Gun Kit 20V MAX with Battery and Charger - Powerful

Our review of the DEWALT Grease Gun Kit 20V MAX finds it best suited to technicians, fleet mechanics, and serious DIYers who need a fast, reliable way to service heavy equipment. The single biggest reason to buy is raw delivery: the motor produces up to 10,000 max PSI and a high-volume pump that pushes up to 5.0 oz per minute, which turns long greasing jobs into quick maintenance tasks. It is a cordless, battery-powered tool designed to replace slower manual pumps while adding reach and control.

Key Features

• High pressure: The motor delivers up to 10,000 max PSI so the tool can power through clogged grease fittings without stalling.
• High-volume pump: The pump moves up to 5.0 oz per minute to speed through high-flow applications and reduce service time.
• Variable speed trigger: Precise flow control lets the operator feather grease delivery for delicate fittings or rapid fill when needed.
• 42 in flexible hose: The long, flexible hose reaches hard-to-access fittings in tight or awkward areas of heavy equipment and machinery.
• Built-in LED and no-mar foot: The bright LED helps locate fittings in dark work areas and the integrated no-mar foot allows the tool to rest without damaging surfaces.
• Pump protection: A pump filter screen and an air-bleeder valve help prevent contamination and simplify priming after cartridge changes.

Who It's For

The DEWALT 20V grease gun is ideal for automotive shops, construction equipment maintenance, agricultural operations, and serious home mechanics who regularly service bearings, pivots, and heavy chassis points. Users who need reliable pressure and continuous flow for many fittings will appreciate the time savings and consistent results.

It is less appropriate for occasional light household use where a manual lever gun is sufficient and more economical. If you rarely grease fittings or need a pocket tool for occasional tasks, a simpler hand pump may be a better choice.
