Description

Milwaukee 2646-20 M18™ 2-Speed Grease Gun

Industry-Leading 10,000 PSI Punch. Pre-Set Precision Dosing Dial. High-Velocity 10 oz/min Delivery.

The Milwaukee M18 2-Speed Grease Gun introduces ultimate fluid-delivery force, meticulous volumetric portion control, and effortless single-handed tool handling to high-volume equipment maintenance lanes. Custom-engineered to eliminate the bone-tiring muscle strain of manual hand lever grease guns and the restrictive logistics of dragging air lines across service bays, this high-performance 18V tool pumps out an industry-leading 10,000 PSI of maximum operating pressure. It provides heavy diesel mechanics, excavator operators, farm equipment maintenance crews, and factory millwrights with a highly nimble platform optimized to blow through grease blockages, clear hardened dirt crusts, and pack heavy-duty bearing tracks instantly.

Meticulous accuracy and rugged jobsite stamina form the core of this M18™ architecture. The 2646-20 features a built-in pre-set grease counter dial, a breakthrough precision tracker that lets service pros select the exact amount of grease required per point to completely eliminate over-lubrication errors that destroy bearing seals. Its versatile 2-speed design gives you total control: click into Speed 1 to unlock maximum pressure for clogged lines, or switch to Speed 2 to blast out an industry-leading 10 oz/min high-flow stream for rapid bulk fills. Built to withstand standard workshop abuse, the self-standing housing includes an extra-long 48-inch flexible hose with spring guard, an integrated air bleeder valve for lightning-fast pump priming, and an ultra-bright onboard LED light to illuminate dark chassis grease points.

Why the Milwaukee® 2848-20 M18™ Cordless Inflator Commands the Fleet Truck:

  • Brute 10,000 PSI Max Pressure: Easily hammers out stubborn, frozen zerk pins and clears hardened debris channels on heavy earthmoving tracks.
  • Smart Pre-Set Volumetric Counter: Built-in dosing dial allows technicians to pump exact quantities to safely match specific bearing tolerances.
  • Dual-Speed Pump Optimization: Seamlessly toggle between Max Pressure (Speed 1) and Max Flow Rate up to 10 oz/min (Speed 2).
  • Extra-Long 48" Flex Hose: Extended high-pressure hose provides exceptional accessibility when maneuvering around tight suspension blocks and machine frames.
  • Rapid Air Bleeder Priming Valve: Specialized release system purges trapped air pockets instantly, ensuring immediate pump priming after standard tube reloads.

Frequently Asked Questions

+ How does the pre-set grease counter dial help prevent bearing damage?
Over-greasing is a primary cause of bearing failure because pushing too much grease into a sealed hub can blow out the rubber seals and let abrasive dirt in. Milwaukee's integrated pre-set counter dial lets you program the exact number of pump strokes needed. Once the grease gun dispenses your specified volume, it automatically stops pumping, giving you consistent dosing without guessing.
+ What is the functional difference between Speed 1 and Speed 2 on this gun?
The 2-speed switch alters the internal gear ratio of the pump motor. Speed 1 optimizes internal torque to hit the maximum 10,000 PSI pressure at a slower flow rate, which is ideal for clearing out clogged zerk fittings or rusted pins. Speed 2 shifts the motor to deliver a maximum flow rate of 10 oz/min at lower pressure, allowing you to quickly fill massive bearing housings, ball joints, or turntable drives.
+ Can I use bulk grease with this tool, or does it only take standard cartridges?
This grease gun features a highly versatile 3-way loading setup. It seamlessly accommodates standard 14.5 oz grease cartridges, can be used for 16 oz bulk grease suction loading directly from a tub, or can be filled using a bulk grease dispenser pump through the integrated filler fitting on the tool head.
+ How do I prime the pump if air gets trapped inside after loading a new grease tube?
Air pockets can trap the pump mechanism and interrupt grease flow. The 2646-20 features a built-in manual air bleeder valve near the top of the cast head block. After reloading a grease cartridge, simply press down on the air bleeder valve button while pushing the follower rod forward. This vents trapped air pockets out of the cylinder head instantly, restoring a solid prime in seconds.
