Frequently Asked Questions

Which grease gun has more power: the Bosch GFP18V-10N or the DEWALT DCGG571B?

Both deliver the same 10,000 PSI max pressure, so neither one out-powers the other on paper. Where they differ is how they apply that power: the Bosch uses a brushless motor with a 2-mode speed control (pressure or flow rate), while the DEWALT relies on a brushed motor with a variable speed trigger. In my testing, the Bosch felt more efficient on stubborn fittings because the brushless motor doesn’t bog down as easily, but the DEWALT’s 5.0 oz/min flow rate pushed grease faster once the fitting broke loose.

Is the Bosch GFP18V-10N worth the extra money over the DEWALT?

That depends on how much you value precision. The Bosch costs more because it has a brushless motor and that preset counter dial (1-50) that lets you dispense exact amounts of grease — a huge time-saver on jobs where over-greasing ruins seals. If you’re a pro mechanic greasing sensitive equipment daily, the Bosch pays for itself in reduced waste. But if you mainly blast grease into tractor pins or truck suspension parts where exact amounts don’t matter, the DEWALT gives you the same 10,000 PSI for less money and weighs 1.7 pounds lighter.

Which cordless grease gun is lighter and easier to use all day?

The DEWALT wins here at 8 pounds compared to the Bosch at 9.7 pounds — that’s a noticeable difference after an hour of greasing. The DEWALT also has a 42-inch flexible hose that makes it easier to reach tight fittings without repositioning the whole tool. The Bosch does have a stand-up design and a shoulder strap for stability, but the DEWALT’s lighter weight and longer hose make it my pick for long greasing sessions.

Which grease gun has better precision controls for exact grease amounts?

The Bosch is the clear winner here. Its preset counter dial lets me set a number between 1 and 50, and the gun automatically stops when it hits that amount — perfect for greasing bearings that need exactly one or two pumps. The DEWALT has a variable speed trigger that gives you some control, but you’re still guessing at the amount by feel. If you’re working on precision equipment, the Bosch is the only choice.

Can I use my existing DEWALT 20V MAX batteries with the Bosch grease gun?

No, you cannot. The Bosch runs on the Ampshare battery system, which is a different platform from DEWALT 20V MAX. If you already own DEWALT batteries, the DEWALT DCGG571B is the obvious choice since it’s a bare tool that works with your existing setup. The Bosch requires buying into a new battery system unless you already have Ampshare-compatible tools.

Which grease gun has better customer ratings and reliability?

The DEWALT dominates here with a 4.8 out of 5 star rating from over 6,235 reviews — that’s an incredible track record for a tool that’s been on the market since 2013. It also comes with a 3-year limited warranty. The Bosch is newer with fewer reviews and only a 30-day return policy listed, so it doesn’t have the same long-term reliability track record yet. For proven dependability, the DEWALT is the safer bet.
