Lincoln 1134 vs Milwaukee M12 Grease Gun: Manual Lever vs Cordless for Shop and Field

Lincoln Industrial 1134 lever grease gun vs Milwaukee M12 2446 cordless grease gun — pressure output, shot counting, battery requirements, cold weather performance, and which to choose for automotive, agricultural, and shop use.

Pressure: Lincoln Wins for Packed Zerks

Lincoln 1134: up to 10,000 PSI. Milwaukee M12: 8,000 PSI maximum. For standard zerks on well-maintained equipment: both clear fittings without issue. For packed or corroded zerks on equipment that has not been serviced in seasons: 10,000 PSI matters. The Lincoln's two-hand lever action physically overcomes resistance the M12 motor cannot.

Choose Lincoln if your equipment has difficult zerks that require maximum pressure. Choose Milwaukee if zerks are accessible and pressure is not the limiting factor.

Operation: Milwaukee Wins for Volume and Precision

The Milwaukee M12 operates with one trigger press — no physical effort. Over 30+ fittings per service, manual lever fatigue is real. The Milwaukee also includes a shot counter — a digital display tracking grease per fitting. The Lincoln has no counter; output per stroke is estimated.

Choose Milwaukee for high-volume servicing, for users with reduced hand strength, or for applications where shot counting improves procedure accuracy (fleet maintenance, equipment manufacturer recommendations).

Power Source: Lincoln Wins for Reliability

The Lincoln runs with no battery. It works in any temperature, after any storage duration, in any location without a power source. The Milwaukee requires a charged M12 battery — in cold weather battery capacity drops and must be managed.

Choose Lincoln if greasing is infrequent (seasonal), if cold weather is a regular factor, or if battery management is not acceptable.

Cost: Lincoln Wins on Initial Price

Lincoln 1134: approximately $50-70. Milwaukee M12 bare tool (no battery): approximately $90-110. Milwaukee M12 kit (with battery and charger): approximately $150-200. If the M12 battery platform is already in use: the bare tool cost is the relevant comparison. If not: the kit cost makes the Milwaukee significantly more expensive.
