Milwaukee® M12 FUEL Ratchets

Milwaukee®'s FUEL designation means the tool is designed with three core technologies: a POWERSTATE brushless motor, REDLINK PLUS intelligence, and REDLITHIUM battery compatibility. 

Milwaukee® (2567-20) M12 FUEL Cordless High Speed 3/8 in. Ratchet

The 2567-20 FUEL ratchet has a drive size of 3/8 in.

The 2567-20 is designed specifically for technicians who need to run fasteners quickly in tight spaces, and its compact head profile makes it one of the most maneuverable 3/8 in. ratchets in the M12 lineup.

Key Specs

• Drive Size: 3/8 in.
• Max Torque: 35 ft-lbs
• Speed: 450 RPM
• Head Profile: 0.75 in. low-profile
• Weight: 1.7 lb (tool only)
• Motor: Brushless (POWERSTATE)
• Features: LED light, variable speed, sub-compact design
• Battery: M12 REDLITHIUM (sold separately)

At 450 RPM and a 0.75 in. head profile, the 2567-20 is purpose-built for confined engine bays and undercarriage work where larger tools simply won't fit. The variable speed trigger gives you precise control, so you’re working with accuracy.

How Much Does It Cost?

The Milwaukee® 2567-20 is available as a tool-only option, which is ideal if you're already running an M12 battery setup. Pricing sits at $114.99 for the bare tool through GenuineTools, offered in secure packaging.

Milwaukee® (2558-22) M12 FUEL Cordless 1/2 in. Ratchet Kit

The 2558-22 comes as a ratchet kit that includes the tool, its batteries, a charger, and a case. 

The 2558-22 steps up to a 1/2 in. drive and is designed to fully replace pneumatic ratchets in professional shop environments. With 60 ft-lbs of max torque and a balanced design, it handles the heavier fastening tasks that the 3/8 in. models aren't built for.

Key Specs

• Drive Size: 1/2 in.
• Max Torque: 60 ft-lbs
• Speed: 175 RPM
• Motor: Brushless (POWERSTATE)
• Weight: 2.7 lb (tool only)
• Features: LED light, variable speed
• Batteries Included: Two M12 2.0Ah REDLITHIUM batteries
• Kit Includes: Tool, (2) 2.0Ah batteries, M12 charger, tool bag

The compact barrel-grip design on the 2558-22 makes one-handed use comfortable and natural, even during extended work sessions. It's great for automotive pros who want the torque of a pneumatic without the compressor setup taking up half the shop floor.

How Much Does It Cost?

The Milwaukee® 2558-22 kit is priced at $227.99 at GenuineTools and includes two M12 2.0Ah batteries, a charger, and a tool bag. This makes it a strong value for shops that don't already own M12 batteries. 

Milwaukee® M12 Non-FUEL Ratchet

The non-FUEL M12 ratchet is the tool for the mechanic who needs reliable cordless performance without committing to the full FUEL investment. It runs on the same M12 battery platform as every other tool in the system.

Milwaukee® (2457-20) M12 12V Cordless 3/8 in. Ratchet

The 2457-20 ratchet has a speed of 250 RPM and delivers 35 ft-lbs of torque. 

The 2457-20 is Milwaukee®'s entry-level M12 ratchet, and it punches above its weight class for general maintenance work. With a brushed motor delivering up to 35 ft-lbs of torque and 250 RPM, it competes surprisingly well with pneumatic ratchets on lighter-duty tasks.

Key Specs

• Drive Size: 3/8 in.
• Max Torque: 35 ft-lbs
• Speed: 250 RPM
• Head Profile: 0.75 in.
• Weight: 1.9 lb
• Motor: Brushed
• Features: LED light, variable-speed metal trigger, on-board fuel gauge
• Battery: M12 (sold separately)

The 2457-20 keeps things simple with a brushed motor, but still includes a variable-speed metal trigger and LED work light for tight-quarters work. At 1.9 lb, it's slightly heavier than the brushless FUEL 2567-20 at 1.7 lb, a difference that adds up over a long shift.

How Much Does It Cost?

The Milwaukee® 2457-20 is the most budget-friendly entry point into the M12 ratchet lineup, available as a tool-only option for $89.99 at GenuineTools. This makes it an accessible choice for anyone already running M12 batteries who wants a capable everyday ratchet without the FUEL price premium.

M12 FUEL vs Non-FUEL: How Do They Compare with Each Other?

Torque Output

The FUEL 2558-22 stands alone at 60 ft-lbs, nearly double the 35 ft-lbs that either 3/8 in. model delivers. For wheel fasteners, drivetrain components, or any stubborn-bolt job, that gap matters.

The two 3/8 in. models match at 35 ft-lbs on paper, but the brushless motor in the FUEL 2567-20 sustains that output more reliably across a full charge.

Speed

The FUEL 2567-20 hits 450 RPM, the fastest in the M12 ratchet lineup, while the Non-FUEL 2457-20 runs at 250 RPM. That extra speed makes a real difference when you're running down a lot of fasteners in a single job.

The FUEL 2558-22 runs slower at 175 RPM, but that's by design: the 1/2 in. drive is about torque delivery, not speed. All three models include variable-speed triggers, so you can dial the pace down for finesse work when accuracy matters more than raw RPM.

Weight & Head Profile Comparison

All three models stay light enough for extended overhead or cramped engine bay work. The FUEL 2567-20 is the lightest at 1.7 lb, followed by the Non-FUEL 2457-20 at 1.9 lb, and the 1/2 in. FUEL 2558-22 at 2.7 lb.

The 0.75 in. head profile on both 3/8 in. models is where Milwaukee® separates these tools from the competition. That compact head fits tight access points under dashboards, in engine bays, and anywhere a standard ratchet head won't clear surrounding hardware.

Drive Size Options

Drive size comes down to the work you're doing. The 3/8 in. drive on the FUEL 2567-20 and Non-FUEL 2457-20 handles most automotive fasteners, underhood work, interior components, and general mechanical tasks.

Step up to the 1/2 in. drive on the FUEL 2558-22 for larger fasteners that demand serious torque, like lug nuts, suspension bolts, or heavy equipment maintenance where 35 ft-lbs falls short.

Applications

The right M12 ratchet depends on the work. The FUEL 2567-20 suits automotive technicians running fasteners in engine bays, suspension components, and underdash spaces.

The FUEL 2558-22 fits shops where heavier fastening is routine: wheel service, drivetrain work, or anything past 35 ft-lbs. The Non-FUEL 2457-20 covers maintenance crews and DIY mechanics who want reliable cordless performance without paying for daily-pro features.

Frequently Asked Questions (FAQs)

Is the Milwaukee® M12 FUEL Ratchet Worth the Extra Money?

For professional use, yes. The brushless motor in the FUEL models delivers more consistent torque under load, longer tool life, and smarter battery management through REDLINK PLUS intelligence. If you're running a ratchet all day, the efficiency gains and durability of a brushless tool pay for themselves over time.

Can M12 FUEL and Non-FUEL Ratchets Use the Same Batteries?

Yes. The 2567-20, 2558-22, and 2457-20 Milwaukee® M12 ratchets run on the same M12 REDLITHIUM battery platform. The 2558-22 kit even comes with two M12 2.0Ah batteries included, which gives you immediate runtime out of the box.

What Is the Head Size Difference Between M12 FUEL and Non-FUEL Ratchets?

Both the M12 FUEL 3/8 in. (2567-20) and the non-FUEL 3/8 in. (2457-20) share the same 0.75 in. low-profile head, so there's no advantage to either model when it comes to accessing tight spaces on the 3/8 in. drive side. The 1/2 in. FUEL ratchet (2558-22) also features a low-profile head design, though its larger drive size naturally requires a slightly larger head to accommodate the increased torque output.

Does GenuineTools Stock Milwaukee® M12 Batteries?

Yes, GenuineTools carries the Milwaukee® M12 battery range, including the 2.0Ah compact, 2.5Ah CP High Output, 3.0Ah XC, 4.0Ah XC, and 5.0Ah XC High Output packs, plus multi-pack starter kits. We also stock the M12 single-bay charger and the M12/M18 multi-voltage charger, so you can power any ratchet in the lineup without buying batteries from a separate source.
