DIYtoolifz Cordless Grease Gun Compatible with Milwaukee 18V Battery — 12000 PSI, 3-Speed Brushless, 39.4" Hose (Tool Only)

DIYtoolifz Cordless Grease Gun is a high-pressure, brushless, battery-powered grease applicator compatible with Milwaukee 18V batteries, delivering up to 12,000 PSI and three adjustable flow speeds for cartridge or bulk loading.

This cordless grease gun is built for technicians, mechanics, and fleet managers who need fast, reliable lubrication on heavy equipment and routine machinery maintenance. It pairs a durable brushless motor with a three-speed control and a 39.4" flexible hose to reach difficult fittings. The tool accepts both standard cartridges and bulk grease, and ships as a bare tool so you can use batteries you already own.

How does the three-speed control improve daily maintenance?

The 3-speed dial lets you match grease flow to the job so you avoid over-lubrication while still clearing stubborn fittings. Low speed gives precise dosing for small components, medium covers general upkeep efficiently, and high speed pushes heavy deposits through clogged or large fittings.

• Low: ~5 oz/min for delicate, low-volume points
• Medium: ~7 oz/min for standard maintenance cycles
• High: ~9 oz/min to overcome blocked or high-demand fittings

Can I use my existing Milwaukee 18V batteries with this grease gun?

Yes — the grease gun is designed to accept Milwaukee 18V batteries so you can leverage batteries from the same ecosystem. Because batteries are sold separately, using a 4.0Ah or higher pack is recommended for extended run time and optimal torque under load.

• Compatible with common Milwaukee 18V battery packs
• Tool-only packaging—battery and charger not included
• 4.0Ah+ recommended for best performance and runtime

What loading options and accessories come with the unit?

This model supports both 14 oz cartridges and bulk grease from pails or drums, giving you the flexibility to choose convenience or economy. The kit includes a long flexible hose, four specialized couplers, an extension pipe, wrenches, and a carrying case so you can start work immediately.

• Accepts standard grease cartridges and bulk-fill operation
• Includes 39.4" steel-braided hose and four pro couplers
• Comes with extension pipe, wrenches, strap, and blow-molded case

How safe and serviceable is the grease gun for heavy-duty work?

The brushless motor design runs cooler and lasts longer than brushed alternatives, while a steel-braided hose and burst-resistant components help keep operation safe under high pressure. Built-in features like an LED work light, kickstand, and quick-purge valve reduce downtime and simplify maintenance tasks.

• Brushless motor for improved durability and efficiency
• Quick-purge valve to remove airlocks for instant start-up
• LED work light, non-slip kickstand, and safety-rated hose

Who is this for: The DIYtoolifz Cordless Grease Gun is aimed at professional mechanics, agricultural and heavy-equipment technicians, fleet maintenance teams, and serious DIYers who require powerful, portable lubrication. If you already use Milwaukee 18V batteries and need a versatile, high-pressure grease solution that handles both cartridge and bulk grease, this tool delivers the reach, pressure, and controls to keep machinery operating smoothly.
