Milwaukee 18V Impact Wrench Kit with Grease Gun for HVAC Pros

Description

If you’ve ever struggled to break loose a stubborn condenser fan blade nut during a summer service call, or needed to quickly lubricate motor bearings on a rooftop unit, you know the frustration of carrying separate tools for every job. We’ve been there—juggling impact wrenches, grease guns, and battery chargers across job sites, wasting precious time and energy that could be spent getting HVAC systems back online.

That’s why we put the Milwaukee 2767-22GR high torque impact wrench grease gun kit through rigorous real-world testing across residential and light commercial HVAC installations. This bundled kit promises to consolidate two essential tools into one 18V platform, and after three months of field use on everything from condenser swaps to furnace installations, we discovered some compelling advantages—along with a few limitations you should know about before buying.

Here’s what matters most: This kit delivers legitimate 1,000 ft-lbs of fastening torque and 1,400 ft-lbs of nut-busting torque, making it powerful enough for virtually every HVAC fastener you’ll encounter, while the included 2-speed grease gun handled bearing maintenance and line set connections without the arm fatigue of manual pumping. For techs running Milwaukee’s M18 battery ecosystem, this combination makes exceptional sense.

Why Milwaukee 2767-22GR High Torque Impact Wrench Grease Gun Kit Stands Out

After testing dozens of impact wrenches and grease guns separately over the years, we immediately noticed how this kit eliminates the battery compatibility headaches that plague multi-brand tool collections. Both tools share the same M18 REDLITHIUM batteries, which means you’re not hunting for different chargers or dealing with dead tools mid-job.

The impact wrench’s DRIVE CONTROL feature genuinely impressed us during condenser fan motor replacements. We could dial down from maximum power to precision mode when working with delicate components, preventing the overtightening issues we’ve seen damage expensive motor mounts. This four-mode system (from 0-1,200 RPM and 0-2,000 RPM ranges) gave us granular control we didn’t have with our previous single-speed impacts.

The grease gun’s 2-speed electronic delivery system proved surprisingly useful for different HVAC applications. High speed (10 oz/min) made quick work of greasing blower motor bearings during PM visits, while low speed (6 oz/min) gave us the precision needed for delicate valve stem packing without over-pressurizing seals.

What really sets this kit apart is the brushless motor technology in both tools. During a particularly demanding commercial RTU installation in July heat, we ran both tools continuously for over four hours on rotation with just two 5.0Ah batteries. Older brushed motors would have overheated or drained batteries twice as fast under that workload.

Key Features & Specifications

• 1,000 ft-lbs Fastening Torque / 1,400 ft-lbs Nut-Busting Torque: Handles everything from 1/4″ sheet metal screws to 3/4″ condenser mounting bolts without requiring a breaker bar
• REDLINK PLUS Intelligence: Prevents overheating and over-discharge that kills batteries prematurely—we saw consistent runtime across dozens of charge cycles
• 4-Mode DRIVE CONTROL: Adjustable speeds (0-1,200 RPM in modes 1-2, 0-2,000 RPM in modes 3-4) prevent fastener damage and give precision control for different materials
• 2-Speed Grease Gun (6-10 oz/min): Variable flow rate handles both bulk lubrication jobs and precision applications without manual pumping
• One-Handed Loading Grease Gun: Accepts both cartridges and bulk loading—critical when you’re balanced on a ladder or working in tight mechanical rooms
• Brushless Motor Design (Both Tools): Extends tool life significantly compared to brushed motors, reduces maintenance needs, and delivers consistent power under load
• Friction Ring Anvil (Impact Wrench): Allows quick socket changes without fumbling with pins—shaves seconds off every fastener change
• (2) M18 5.0Ah REDLITHIUM Batteries: Enough capacity for full-day operation on typical residential service calls
• Multi-Voltage Charger: Simultaneously charges both batteries, so you’re always ready for the next job
• LED Work Lights (Both Tools): Illuminates dark spaces like crawlspaces and attic installations where you’re actually working

Hands-On Performance Testing

We tested the Milwaukee 2767-22GR across three months of varied HVAC work to see how it performed beyond controlled conditions. Our first major test came during a complete residential AC condenser replacement where we needed to remove severely corroded mounting bolts that had been exposed to coastal salt air for 15 years.

On Mode 4 (maximum power), the impact wrench broke loose 5/8″ bolts that we honestly expected to cut off with an angle grinder. The 1,400 ft-lbs breakaway torque wasn’t marketing exaggeration—it delivered genuine nut-busting capability that saved us at least 30 minutes of cutting and drilling. We compared this directly against a colleague’s DeWalt DCF899 on the same job site, and the Milwaukee had noticeably more breakaway authority on the most stubborn fasteners.

The grease gun faced its toughest challenge during preventive maintenance on ten rooftop package units. Each unit required bearing lubrication on blower motors and condenser fan motors—typically 20-30 pumps per bearing with a manual grease gun. The Milwaukee’s powered delivery eliminated the hand cramping that usually follows these marathon PM days. We measured our time per unit: 8 minutes with the Milwaukee versus 14 minutes with our manual Alemite gun. Over ten units, that’s an hour saved.

Battery performance exceeded our expectations for field use. On a typical residential service day involving furnace diagnostics, blower motor replacement, and ductwork modifications, we used approximately 40% of one 5.0Ah battery across both tools. The impact wrench is the heavier consumer—we measured roughly 25-30 high-torque impacts per 1% battery, while the grease gun used minimal power even during extended lubrication sessions.

We did encounter some limitations during commercial work. When installing a 5-ton rooftop unit with lag bolts requiring sustained high torque, the impact wrench triggered thermal protection twice during a 45-minute installation period. The tool shut down for about 90 seconds to cool before resuming—not a dealbreaker, but worth noting if you’re doing continuous heavy-duty fastening in hot environments. Older brushed impacts would have simply burned out, so the protection system is actually working as designed.

The grease gun’s 10,000 PSI maximum pressure handled standard zerk fittings perfectly, but we noticed it struggled slightly with extremely clogged fittings that hadn’t been serviced in years. A manual gun with leverage would sometimes power through what the Milwaukee couldn’t. That said, this happened in maybe 5% of situations—usually on severely neglected equipment.

What We Liked (Pros)

Legitimate Professional-Grade Torque: This isn’t a homeowner impact wrench pretending to be professional equipment. The 1,000 ft-lbs fastening torque handled every HVAC application we threw at it, from mounting 4-ton condensers to removing seized compressor bolts. We never once wished for more power, which is saying something for techs accustomed to pneumatic impacts.

Battery Platform Consolidation: If you’re already running Milwaukee M18 tools, this kit instantly becomes more valuable. We used the same batteries in our M18 FUEL drill, circular saw, and shop
