Milwaukee M18 2-Spd Grease Gun Bare Tool - 10,000 PSI Power

Our review of the Milwaukee M18 2-Spd Grease Gun finds it aimed squarely at service techs, fleet mechanics, and serious DIYers who need reliable, repeatable lubrication without fuss. The single biggest reason to consider this grease gun is its combination of an industry leading 10,000 PSI max operating pressure and a patent pending pre-set grease counter that lets users dispense precise amounts of grease, which is a real time saver for routine maintenance and preventative service work.

Key Features

• 10,000 PSI max pressure: Delivers the force needed to reach stubborn fittings and push grease through tight lines for thorough lubrication.
• 48in flexible hose: Provides access to hard-to-reach grease points on trucks, heavy equipment, and in cramped engine bays without awkward repositioning.
• Pre-set grease counter dial: Allows technicians to measure and dispense repeatable, precise amounts of grease for consistent service records and reduced waste.
• Two-speed design: Lets users switch between max pressure for stubborn fittings and max flow rate for faster fills when pressure is not required.
• Air bleeder and LED: The air bleeder valve speeds priming and the on-board LED improves visibility when working in low-light areas.
• Lock-on/lock-off trigger: Adds user convenience for extended jobs and helps limit hand fatigue during repetitive greasing tasks.

Who It's For

This grease gun is best for professionals and hardworking hobbyists who service fleets, agricultural or construction equipment, and heavy-duty trucks where high pressure and precision matter. The tool's pre-set grease counter and high PSI make it suitable for scheduled maintenance where consistent grease volumes are required.

It is less appropriate for occasional home users who only perform very light greasing; the bare tool format also means buyers will need to provide an M18 battery if they do not already own one. Those wanting a kit with battery and charger should look for bundled options instead.

Pros & Cons

Pros

• High pressure capability makes greasing difficult fittings straightforward and effective.
• Precision through the pre-set grease counter reduces over-application and improves consistency between jobs.
• Flexible 48in hose and on-board LED increase access and usability in tight or poorly lit spaces.
• Lock-on trigger and shoulder strap capability lower user fatigue during long tasks.

Cons

• Sold as a bare tool, so an M18 battery must be supplied separately if you do not already have one.
• The professional features may be more than required for very occasional light-duty home use.

Our Verdict

The Milwaukee M18 2-Spd Grease Gun is a solid choice for professionals who need high pressure and measured dispensing in one package; its 10,000 PSI capability and pre-set grease counter deliver both power and repeatability. For technicians who already use the M18 platform, the bare tool format represents good value because it adds capability without duplicating battery investments.
