A Milwaukee battery grease gun typically costs $200-$500, depending on model, included batteries, charger, and seller. A tool-only M18 model is usually about $300-$350, while a kit with a battery and charger often runs $400-$500; the M12 model can cost less. The biggest price difference is whether the purchase includes the battery system, not the grease gun’s basic function.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| M12 grease gun, tool only | $180 | $220 | $270 | Compact 12-volt model; availability varies |
| M18 grease gun, tool only | $270 | $320 | $380 | Common 18-volt model, usually sold without battery |
| M18 kit with battery and charger | $380 | $440 | $520 | Kit contents and battery capacity affect price |
| Grease gun hose or accessory | $15 | $35 | $75 | Replacement hose, coupler, or specialty fitting |
| Typical purchase total | $200 | $340 | $500 | Before sales tax; assumes regular retail pricing |
What Milwaukee grease guns cost by model and kit
Milwaukee’s battery-powered grease guns are sold mainly in M12 and M18 versions. The M12 2446-20 is a compact option, while the M18 2646-20 is a common full-size tool. Prices differ by retailer and stock, and model numbers or included accessories can change between packages.
For most buyers, budget $270-$380 for an M18 tool-only purchase or $380-$520 for a complete kit. Tool-only means the package generally does not include a battery or charger. A buyer who already owns compatible batteries may therefore pay substantially less than someone starting a new platform.
Typical listed prices are not guarantees. Promotional discounts, clearance stock, and bundled offers can lower the checkout price. Conversely, limited availability or a seller listing an older package can push the price above the usual range. Verify the exact model number, battery count, charger, and case before comparing offers.
Assumptions: U.S. retail pricing, standard tool package, ordinary access, before sales tax. Regional freight, promotions, and inventory can change the final quote.
How batteries, labor, and accessories shape the quote
A retail purchase has no installation labor charge: the buyer loads grease, installs a charged battery, and uses the tool. The main price components are the gun, battery platform, charger, and any replacement or specialty accessories. A repair shop may instead charge diagnostic and repair labor if the tool is malfunctioning.
| Quote component | Low | Typical | High | What changes the price |
|---|---|---|---|---|
| Grease gun, tool only | $180 | $300 | $380 | M12 versus M18 and seller discount |
| Battery and charger | $80 | $140 | $220 | Battery capacity, kit format, and charger type |
| Hose or coupler | $15 | $35 | $75 | Length, pressure rating, and fitting style |
| Repair diagnosis and labor | $40 | $90 | $180 | Shop rate, troubleshooting time, and parts |
| Sales tax and delivery | $0 | $20 | $55 | Local tax rate, shipping weight, and seller terms |
Repair pricing is an estimate rather than a fixed Milwaukee service tariff. Independent repair shops may charge around $75-$125 per hour, with a one-hour minimum or separate diagnostic fee. A simple switch or hose issue can cost less than a motor, gearbox, or electrical repair requiring parts.
Battery and charger costs can add $80-$220 if the buyer does not already own a compatible pack. Grease tubes are also an ongoing supply expense, but they are not normally included in the tool’s purchase price.
Battery platform, grease capacity, and model numbers matter
The largest buying distinction is the battery platform. The M12 model is smaller and can suit lighter maintenance work or users who value compact handling. The M18 model is a common choice for frequent equipment and vehicle lubrication. The M18 tool-only price can look high, but it may be the lower-cost option for someone already invested in M18 batteries.
Grease-gun specifications also affect value. Milwaukee M18 2646-series models are commonly rated for high working pressure, and some versions offer selectable output settings. Confirm the specific model’s published pressure, flow rate, hose length, and bulk-loading options rather than assuming every package has identical features. A higher-capacity battery can extend run time but adds weight and may cost more.
Compare model numbers and package contents before treating two listings as equivalent. A number ending in “-20” commonly identifies a bare tool package, while kit suffixes may indicate a battery, charger, or carrying case. Retailer descriptions can be incomplete, so check the package list and product label.
Also check whether the tool accepts the buyer’s intended grease-loading method. Cartridge size, bulk filling, and suction loading can affect convenience and compatibility. A replacement hose or coupler may be needed for a particular machine’s fittings; budget roughly $15-$75 depending on the part.
Three realistic Milwaukee grease gun purchase totals
A low-cost scenario assumes the buyer already owns a compatible M18 battery and charger and finds a discounted 2646-20. A midrange scenario includes a new M18 tool and a modest battery purchase. A high scenario reflects a full kit, larger battery, delivery, and tax.
| Purchase scenario | Tool and package | Extra costs | Estimated total | Approximate unit cost |
|---|---|---|---|---|
| Existing M18 owner | Tool-only M18, $275-$310 | Tax or delivery, $10-$30 | $285-$340 | $285-$340 per gun |
| New M18 buyer | Tool-only M18, $300-$350 | Battery and charger, $100-$180 | $400-$550 | $400-$550 per setup |
| Complete kit buyer | M18 kit, $400-$490 | Tax or delivery, $15-$45 | $415-$535 | $415-$535 per kit |
The M12 option can be a lower-cost complete setup when the buyer already owns M12 batteries. A tool-only M12 purchase around $180-$270 may rise to approximately $270-$400 when a separate battery and charger are needed. Prices depend on current stock and whether the model is actively sold by major retailers.
The least expensive advertised price is not always the lowest complete-system price. Add the cost of a compatible battery, charger, required hose, and delivery before comparing the final totals.
Regional retail prices and delivery can shift the total
Milwaukee tools generally have national suggested pricing, but actual shelf prices vary by retailer, local competition, and inventory. A metro-area sale or online promotion may be 5%-15% below a typical price. Rural locations with fewer retailers or limited stock may run roughly 5%-12% higher, particularly when shipping or special ordering is involved.
These are practical comparison ranges, not guaranteed regional price rules. Store pickup may avoid shipping charges, while online listings can add $10-$35 for delivery or place an item behind a minimum-order threshold. Sales tax varies by state and locality; a $400 kit can add roughly $0-$40 in tax depending on where it is purchased.
Compare the same model and package at two or three sellers, including tax and shipping. A $20 lower listing can lose its advantage if it excludes the charger or charges for delivery. Check whether a seller is authorized and what return or warranty terms apply.
Repairing an existing gun versus buying another
A worn hose, coupler, or simple connection problem may be economical to repair. Common replacement accessories typically cost $15-$75, and a local shop’s diagnosis plus labor can bring a straightforward repair to around $60-$150. More extensive electrical or drive repairs may reach $150-$300 once parts and labor are included.
Compare a repair estimate with the replacement price for the same platform. If a repair approaches $200 or more on an older tool, a discounted bare tool may cost less, particularly when the battery and charger remain usable. A new complete kit is harder to justify if the existing battery system is in good condition and compatible.
Use the total repair quote, not just the parts price, to decide whether replacement makes financial sense. Ask whether the shop charges a diagnostic fee if the repair is declined, and whether replacement parts carry a separate warranty.
Which costs can be avoided without sacrificing output
Existing M12 or M18 batteries are the clearest source of savings. Choose a tool-only package when it matches the buyer’s platform, but confirm that the battery is in usable condition and the charger is available. Buying another battery solely for occasional use may make a kit more sensible if the kit price is close to the bare-tool-plus-battery total.
Compare standard packages before paying extra for accessories that may not be needed. A specialty hose, extra coupler, or larger battery can be useful for frequent work or difficult fittings, but can add $15-$220. Avoid paying a premium for a case or bundle items already owned.
Set a complete-system budget before choosing the listing. Include the gun, compatible battery, charger, delivery, tax, and any required hose. For an occasional user, a manual grease gun may cost $20-$60 and avoid battery expense, though it requires more physical effort and is slower for repeated lubrication.
When comparing quotes, request the exact model number and itemized package contents. Check sale timing and local pickup availability, but do not assume a promotional price is comparable unless battery capacity and warranty terms match. A repair estimate is worth getting when the existing gun has a small, identifiable fault rather than widespread wear.
Hose, grease, and warranty expenses after purchase
Replacement hoses and couplers are the most likely incidental expenses. Standard replacement parts often fall in the $15-$75 range, while specialty fittings or longer high-pressure hoses may cost more. Grease cartridges commonly cost about $5-$15 each depending on formulation, brand, and package size; bulk grease can have a different per-pound price and requires a compatible loading approach.
Warranty coverage depends on the exact tool, purchase date, seller, and applicable Milwaukee terms. Keep the receipt and model information, and verify current coverage directly in the product documentation. Warranty service may not cover ordinary wear, misuse, or accessories in the same way as the tool itself.
For budgeting, allow about $20-$100 for initial grease and a commonly needed hose or coupler, separate from the gun price. Routine cleaning and correct loading help reduce avoidable blockages and service calls, but no maintenance schedule guarantees a particular tool life.
