    Can you bulk fill this grease gun
    ByApr 28, 2025
    1 Answer | 
    Answer This Question

    Yes, you can bulk fill the M12 Grease Gun. The grease gun features an air bleeder valve which acts as a priming mechanism to provide quick flow, making it suitable for bulk filling applications.

      Does this come with a locking tip, or is that something that must be purchased separately?

        No, but that might be a good thing.  I’m never sure I’m not injecting dirt into my cylinders.

                            Where is the shoulder strap that is clearly written in the product description? I did not get one. It?s the same thing with the m12 fuel circ saw and its rip fence, claims to be included but isn?t.

                                Does the unit come with a 90* end for the hose?

                                No. It only has a straight end. The end is removable if you needed to change it. The tip is standard and the hose is removable too. If you wanted a different length or flexibility. The factory arrangement works for me. All my zirks are easily accessible. 

                                By|May 24, 2023

                                  No the unit does not come with a 90 degree end. The hose is straight

                                      The greese gun comes with a normal coupler. The coupler is easily taken off to attach different assortment of tips. I have no problem switching out the coupler to a needle point tip in a minute or two.

                                      By|Jan 4, 2022

                                        No, straight only.

                                                Hose is relatively long and seems to work fine unfortunately mine has stopped pumping grease I have primed several times and still will not work I have even packed grease around plunger doesn't build pressure any more.

                                                  The milwaukee right angle die grinder has worked great for many different applications from cleaning and polishing bushings and sheaves to deburring conduit and unistrut. The compact size allows it to get in to a lot of tough spots.

                                                  Makes easy work of greasing my suspension. Old, manual gun, was a pain. One hand to hold the grease fitting, one hand to hold the gun, one hand to pump. Was always one hand short. So much easier now. And size is not much larger than manual grease gun.

                                                  The 1/4" right angle die grinder seemed like an luxury purchase for a the occasional home shade tree mechanic, when a scraper or razor blade is the usual tool of choice, but it was so nice to use a 3M Roloc disk to clean the hardened paper gasket from the water pump housing and mating engine block surface when replacing a water pump in my 1996 Daihatsu Hijet Japanese mini truck. It'll also come in very handy at lower speed to strip the paint and mild surface rust from the steel wheel rims before powder coating them. This M12 tool is a no-brainer decision for professional mechanics but also a worthwhile purchase for occasional home use because most people would prefer to spend some money to avoid the unpleasant tedious labor this tool eliminates. The previous version of the M12 right angle die grinder was a bit anemic but it's very difficult to stall this newer brushless version. The Milwaukee tool bundles offer the best value but are also likely to result in having way more chargers than you need, but you can never have too many M12 batteries, Don't forget to buy the accessories you need to use the M12 die grinder. The 3M woven abrasive pads are very handy for removing gaskets and sealants, as are the 3M disks with abrasive fingers. Other applications might require sanding disks, wire brushes or carbide burrs. Ensure that any accessories are rated for 25,000 RPM and always wear eye protection. ANSI rated cut resistant gloves are recommended as well.

                                                  This grease gun works great for my small hobby farm. Greasing the skid steer and tractor is a much cleaner process.

                                                  I bought this Milwaukee grease gun from Home Depot. Its been working flawlessly. I was doing all the service work on my Excavation equipment, and dump trucks. when I backed my dump truck out of my building I accidentally drove over my grease gun. I was really surprised it still worked. Theres some broken parts, but the darn thing still works. Thats why I only buy Milwaukee tools, because there extreme tuff!!!
