For automotive work, trailers, tractors, lawn equipment, heavy machinery, UTVs, and other gear with grease fittings, being able to apply consistent pressure without pumping by hand can save a ton of time and frustration. It’s especially useful if you’re servicing multiple fittings at once or trying to keep vehicles and equipment on a regular maintenance schedule. A manual grease gun can still work fine for occasional use, but if you’re doing this often, a cordless model is a serious upgrade.With this deal we found at Amazon, the DeWalt 20V Max Cordless Grease Gun Kit is on sale for just $224, which is nearly 40% off on a trusted name brand tool that also has nearly 6,000 five-star ratings at Amazon. The grease gun delivers up to 10,000 max psi to help push through clogged grease fittings, and the high volume pump can move up to 5 ounces per minute for faster applications. The kit also includes a 20V Max XR 4.0Ah battery, fast charger, shoulder strap, and box, so you’re not just getting the bare tool.DeWalt 20V Max Cordless Grease Gun Kit, $224 (was $369) at AmazonCheck PriceAdvertisementAdvertisementThe variable speed trigger helps control grease flow, while the 42-inch flexible hose makes it much easier to reach tight fittings under vehicles, around suspension components, or on equipment where access is limited. The built-in LED light is also a nice touch if you’re working under a car, inside a dark garage, or around machinery where fittings aren’t always easy to see. DeWalt says the tool can handle up to 16 cartridges per charge with a single 4.0Ah battery, which makes it a solid option for regular equipment servicing.This probably isn’t necessary if you only grease one fitting once or twice a year, but for mechanics, farmers, fleet owners, trailer owners, and anyone maintaining multiple vehicles or pieces of equipment, it’s a tool that can pay for itself in saved time.Related: Amazon’s ‘Powerful’ $200 Electric Grease Gun Is Now 40% OffOne reviewer commented, “This battery-operated grease gun makes the work go so fast and easy.
