Friction is the quiet killer of machinery. It does not announce itself; it simply wears bearings, overheats joints and turns a $50 component into a $500 failure. The Hydra Prime exists to interrupt that process — a cordless grease gun that delivers industrial-grade pressure with the freedom of a battery, so the maintenance that prevents breakdowns actually gets done.
At its heart is a 960 W brushless motor driving up to 69 MPa (10,000 PSI) of delivery pressure — enough to push grease through the tightest fittings on heavy equipment, excavator pins, truck chassis and agricultural machinery. The high-pressure 50 cm hose handles the rated working pressure without strain, and the trigger-controlled speed adjustment lets you switch between precise low-flow metering and rapid bulk delivery with a single press. A built-in work lamp illuminates dark undercarriages, the anti-slip handle keeps control in oily hands, and the vented housing sheds heat so the tool keeps its pace through a full service bay of fittings. It runs on the ubiquitous Makita 18 V battery platform, so it shares power packs with the rest of your cordless fleet.
There is a reason workshops measure grease guns in hours of continuous use, not in box specs. The Hydra Prime was built for that metric: 410 to 570 g of lubricant capacity depending on configuration, a rugged plastic case for transport, and nine accessories to reach the fittings other tools cannot. Maintenance is not glamorous. But it is the difference between a machine that runs and a machine that fails — and this is the tool that makes the difference routine.
Friction is not a fact of life. It is a management failure — and The Hydra Prime is the correction.

Frequently Asked Questions
Q: Which batteries does The Hydra Prime use?
A: It runs on the Makita 18 V battery platform. Choose the configuration with no battery, one 4.0 Ah battery, or two batteries plus a charger, depending on your existing tool kit.
Q: How much pressure can it actually deliver?
A: The brushless pump generates up to 69 MPa (10,000 PSI), which is sufficient for the tightest heavy-duty grease fittings found on trucks, tractors, excavators and industrial machinery.
Q: Can I control the grease flow precisely?
A: Yes. The trigger doubles as a speed control — a light press delivers a slow, precise flow for metering, while a full press switches to rapid bulk delivery.
Q: Is it suitable for dark or awkward service areas?
A: Absolutely. The integrated work lamp illuminates the fitting area, and the 50 cm high-pressure hose plus nine included accessories help you reach confined spaces.
Q: What is in the box?
A: The cordless grease gun, 9 accessories, and a rugged plastic case for storage and transport. Battery and charger depend on the configuration you select.
Q: How do I maintain the tool itself?
A: The vented housing dissipates heat during continuous use, and the brushless motor eliminates brush replacement. Wipe the hose and fittings after use and store in the included case.
Q: Can The Hydra Prime handle heavy equipment grease?
A: Yes — with 69 MPa of delivery pressure it pushes NLGI #2 and #3 greases through the long lines and tight zerk fittings found on excavators, tractors, truck chassis and industrial machinery, which is exactly the workload these tools are rated for.
Q: How many fittings can I service per charge?
A: On a 4.0 Ah Makita battery you can expect dozens of fittings per charge in normal service — the brushless pump only draws power while delivering grease, so intermittent use between fittings extends run time dramatically compared to continuously-running motor designs.
