Buying guide: best cordless grease gun for home mechanics
Pressure and flow
Every pick except the Milwaukee listing states 12,000 PSI max pressure, so pressure does not separate the set. Flow rate does: 5.3 oz/min on the CICZ and OFISPEED guns, 6 oz/min on the SXBSXB gun, and 6 to 8 oz/min on the SUROVO gun.
Battery platform
Match the gun to batteries already in the garage. The CICZ and SXBSXB guns fit DeWalt 20V MAX batteries, the SUROVO gun fits Milwaukee 18V batteries, and the OFISPEED kit brings 2 x 4.0Ah batteries of its own. A 4.0Ah or higher capacity battery is recommended for full pressure on the CICZ and SUROVO listings. For battery sizing, see 2Ah vs 5Ah 20V battery.
Hose and couplers
A 39.4 inch hose reaches fittings under trucks and tractors without moving the gun. The OFISPEED gun pairs its hose with a quick locking coupler, the SUROVO and CICZ guns list 4 couplers, and the SXBSXB gun lists a 90° swivel coupler.
Bare tool or kit
The CICZ, SXBSXB and SUROVO guns ship without a battery or charger, and the Milwaukee gun is listed as tool only. Only the OFISPEED kit includes 2 batteries and a charger. A bare tool suits a garage where batteries are already on the shelf.
Use rated jack stands on solid ground, wear eye protection with power and air tools, keep fuel-burning equipment out of a closed garage, and follow the manual for every tool. Read our Safety Disclaimer.
Garage Fit Check
- Shelf space: the Milwaukee gun measures 20.0 x 10.0 x 4.5 inches, and the OFISPEED gun measures 16.14 x 12.52 x 4.65 inches.
- Power: DeWalt 20V MAX fits the CICZ and SXBSXB guns, Milwaukee 18V fits the SUROVO gun, and the OFISPEED kit brings 2 x 4.0Ah batteries.
- Storage: the CICZ and SUROVO listings include a carrying case; the other listings state no case.
- Grease: all 4 guns that state loading take 14 oz cartridges or 600 cc bulk grease.
