Milwaukee 3610-22CT M18 18V Li-ion Brushless Cordless Compac

The Verdict

The Milwaukee 3610-22CT is the drill you grab when the job is in a cramped corner, not when you’re mixing mortar. This compact brushless hammer drill from Milwaukee’s M18 lineup packs surprising punch for its size, but it comes with compromises that matter depending on what you’re drilling.

What’s in the Box

The 3610-22CT kit ships with the drill itself, two M18 CP2.0 compact batteries, a rapid charger, and a contractor bag. Notably absent: a side handle, belt clip, or carrying case. The bag is decent but flimsy compared to Milwaukee’s hard cases. If you’re the type who throws tools in a truck bed, budget for a proper case.

Performance That Surprises

Here’s the headline: this thing delivers 1,500 in-lbs of torque from a housing just 6.3 inches long. That’s real power — enough to drive 3-inch deck screws without pre-drilling and handle 1-inch spade bits through dimensional lumber. The brushless motor is the star, providing better runtime and more consistent power than the older brushed compact models.

The hammer function is genuinely useful for 3/16-inch and 1/4-inch masonry anchors in block or brick. It’s not a rotary hammer — don’t expect to bore through foundation walls — but for hanging shelving or conduit straps, it does the job.

Ergonomics matter on a compact drill, and Milwaukee nailed the balance. At 2.4 pounds with the CP2.0 battery, it’s light enough for overhead work without arm fatigue. The rubber overmold grips well even with gloved hands.

What Buyers Consistently Praise

The 4.6-star rating across 229 reviews reflects real-world satisfaction. One buyer notes, “I was skeptical about the compact version but it drives lags like my full-size Fuel. The size advantage is huge when you’re working inside cabinets.” Another echoes that sentiment: “Perfect for tight spots. I keep this as my go-to for electrical work where I’m constantly in cramped panels.”

The kit value gets repeated mentions — buyers appreciate getting two batteries and a rapid charger rather than paying extra piecemeal.

Where It Falls Short

Let’s be honest about the downsides. The included CP2.0 batteries are compact for a reason — they keep the weight down but sacrifice runtime. Under heavy load, like drilling 1-inch holes continuously, expect roughly 20-25 minutes of actual use per battery. You’ll want larger batteries for serious work, but they add weight and defeat the compact advantage.

The chuck is metal but not the all-metal unit on the Fuel line. It’s fine for general use but lacks that premium feel and long-term durability of the higher-end model. After heavy use, some users report the chuck needing occasional tightening.

And that missing side handle? For a drill with this much torque, you’ll want one for bigger bits. It’s a $15-20 add-on, but it should ship in the box.

Who Should Buy This

• Electricians and low-voltage techs: The compact head and light weight make this ideal for panel work, conduit, and tight attic spaces
• DIYers with Milwaukee batteries: If you’re already in the M18 system, this is a smart addition for everyday drilling
• Plumbers and HVAC pros: Reaching into tight cabinet bays and stud pockets is where this drill shines

Skip it if: You primarily drill large holes or drive heavy lags all day — get the full-size Fuel instead. Also skip if you’re starting fresh with no Milwaukee batteries; the compact power isn’t worth investing in a new battery platform.

FAQ

Can this drill handle concrete? Yes, for light masonry work — anchors, tapcons, small holes up to 1/4-inch. For anything bigger, rent a rotary hammer.

Is the 3610-22CT compatible with all M18 batteries? Yes, all M18 batteries work, including the high-output 12.0Ah. Just know that bigger batteries add weight and shift the balance.

What’s the difference between this and the 2904-20 Fuel version? The Fuel has more torque (1,200 vs 1,500 in-lbs in this model’s favor actually), a metal chuck, and better durability for daily professional abuse. The 3610 is lighter and more affordable.

The Verdict

Buy it if you need a compact, capable drill for tight spaces and already own M18 batteries. Skip it if you need all-day heavy drilling or want the premium chuck of the Fuel line.

Rating: 4.6/5 — this is a genuinely useful tool with honest limitations. The size-to-power ratio is excellent, the brushless motor is reliable, and the kit value is fair. Just know what you’re buying: a specialist for cramped work, not a do-everything monster.
