From D.I.Y to Professional drilling. Our 12V, 16.8V, and 21V platforms deliver consistent torque and professional reliability for every task.
You’re not alone. If you’ve been sourcing cordless grease guns for your market, you’ve likely run into these frustrating customer complaints:
Stalls Under High PSI: Weak motors or fragile pumps stall out against clogged Zerk fittings, failing to push thick grease into heavy machinery joints.
Messy Leaks & Air Locks: Low-end couplers leak grease everywhere under pressure, while poor air bleeder valves cause frequent air locks that stop grease flow mid-job.
Battery Strain & Slow Delivery: Pumping thick grease in cold weather rapidly drains cheap battery packs, triggers thermal cutoffs, or pumps too slowly to service big fleets.
Heavy & Awkward Handling: Clunky, poorly balanced bodies that are painful to carry around job sites, paired with short, rigid hoses that can’t reach tight fitting angles.
The real challenge? Finding a cordless grease gun that busts through stubborn clogs with high pressure — fast, leak-free, and effortless to load.
Explore our high-pressure range of cordless grease guns, engineered for rapid, effortless lubrication across heavy machinery, agricultural equipment, and automotive maintenance. Powered by robust motor drives delivering exceptional operating pressure and high flow rates, our series eliminates manual hand-pumping fatigue and accelerates equipment servicing on demanding job sites.
Powered by a heavy-duty motor drive that delivers up to 10,000 PSI (690 Bar) of max working pressure. Effortlessly forces grease through clogged grease fittings and delivers high flow rates (up to 5.0–7.5 oz/min) for fast, thorough equipment lubrication.
Supports flexible 3-way loading: standard 14 oz. grease cartridges, bulk suction, or filler pump loading. Built with an intuitive air bleeder valve that quickly purges trapped air pockets to prevent air-locks and ensure smooth, uninterrupted priming.
Equipped with a long, reinforced flexible high-pressure hose (e.g., 30″ to 42″) and heavy-duty coupler to easily reach recessed or tight lubrication points. Features a bright front-mounted LED work light to illuminate dark grease fittings under vehicles and machinery.
Designed with built-in shoulder strap loops and a stable stand base for comfortable, hands-free operation and easy carrying around large job sites. Powered by a flexible 21V Makita-style pin platform, ensuring seamless battery sharing across your entire tool lineup.

👉 Looking for a cordless drill manufacturer/ supplier in China you can rely on?
Let’s talk — and get you the performance your customers expect.
High Working Pressure (Up to 10,000 PSI / 690 Bar): Generates more than enough force to clear clogged grease fittings (zerks) on heavy trucks, farm tractors, and construction machinery.
High Flow Rate (Up to 4.0–5.0 oz/min or 110–140 g/min): Dispenses grease 5x faster than a manual lever gun. You can grease heavy equipment joints in seconds with just a pull of the trigger.
It supports 3-Way Loading:
Standard Cartridge: Pop in a standard 14 oz (400g) grease tube.
Bulk Suction: Dip the barrel into a bucket and pull the rod back to load.
Filler/Dispenser Pump: Connect to a bulk grease pump via the filler valve.
Air pockets inside the barrel stop grease from flowing.
The Bleeder Valve: Simply press or turn the valve button after loading a new tube to bleed trapped air in seconds, restoring smooth grease flow immediately.
Extra-Long Flex Hose (usually 30"–42" / 75cm–100cm): Reaches tight, awkward zerks on deep vehicle undercarriages easily.
High-Pressure Rated: Reinforced to handle over 10,000 PSI without kinking or bursting.
Greasing requires efficient power use:
A standard 2.0Ah battery can pump out up to 5 to 7 full grease cartridges on one charge—enough to service multiple heavy trucks or tractors.
Yes! A bright LED light is built near the hose mount to illuminate dark zerk fittings, under chassis, and inside dark machinery compartments so you don't miss a spot.
It gives you total control over grease output:
Low Speed / Light Pull: For small bearings and delicate joints that need precise, slow greasing without blowing out rubber seals.
High Speed / Full Pull: For fast, heavy-duty greasing on big machinery bushings.
Zero Hand Fatigue: No more pumping a heavy lever hundreds of times with sore arms.
One-Handed Operation: Leaves your other hand free to hold the hose coupler securely onto stubborn grease fittings.
Yes, 100%! The complete kit includes:
1× Cordless Grease Gun Host & Barrel
Rechargeable Lithium-Ion Battery & Fast Charger
1× High-Pressure Flexible Hose with Coupler
1× Shoulder Strap & Carrying Case / Bag
(Charge the battery, drop in a grease cartridge, bleed the air valve, and you are ready to grease effortless!)
