Are you looking for a portable band saw that cuts through metal like butter? DeWalt has been a trusted name in power tools for decades. Their portable band saw lineup in 2026 offers something for every trade professional and serious DIYer.

Whether you need to slice through conduit overhead, cut strut on a job site, or trim pipe in a tight crawl space, DeWalt portable band saws deliver real results. But with several models on the market, how do you pick the right one?

In this review, we break down every current DeWalt portable band saw. We look at cut capacity, battery life, weight, blade speed, and real-world performance. We also compare cordless and corded options so you can make a smart buying decision.

Key Takeaways

• DeWalt offers five main portable band saw models in 2026, ranging from the compact ATOMIC DCS377B to the full-size corded DWM120K. Each model fills a different role, so your best choice depends on the materials you cut and where you work.
• The DCS374B remains the most popular cordless option with its 5-inch deep cut capacity and 20V MAX brushless motor. It handles schedule 40 pipe, angle iron, and strut with ease. This is the go-to pick for plumbers, electricians, and general contractors.
• The newer DCS378B mid-size bandsaw fills the gap between compact and full-size models. It delivers 535 MWO at 570 SFPM blade speed. It can make up to 120 cuts per charge through 12-gauge strut. That is impressive for a mid-size tool.
• Weight matters on the job site. The ATOMIC DCS377B weighs just 6.6 pounds, making it the lightest option for one-handed and overhead work. The DCS374B weighs about 12.2 pounds. The corded DWM120K tips the scale at over 14 pounds.
• All cordless DeWalt band saws run on the 20V MAX battery platform. This means they share batteries with your existing DeWalt cordless tools. The DCS374B is also compatible with FLEXVOLT batteries for extended runtime.
• Blade availability is excellent across all models. DeWalt sells replacement blades in 18 TPI, 24 TPI, and 14/18 variable TPI options. You can find them at most hardware stores and online.

DeWalt DCS374B 20V MAX XR Deep Cut Band Saw

The DeWalt DCS374B is the flagship cordless portable band saw in the DeWalt lineup. It uses a 20V MAX XR brushless motor that delivers long runtime and consistent power. The brushless design also means less heat and longer motor life.

This saw cuts up to 5 inches by 4-3/4 inches in rectangular material. It handles round material up to 4 inches in diameter. That is enough capacity for schedule 40 pipe, unistrut, angle iron, and threaded rod.

The variable speed dial lets you adjust blade speed to match the material. Softer metals like aluminum need faster speeds. Harder materials like steel benefit from slower, steadier cuts. The integrated hang hook lets you store the saw on scaffolding or pipe racks between cuts.

At roughly 12.2 pounds (without battery), this saw is light enough for extended use. It balances well in your hands, and the front grip area provides solid control during cuts. This model accepts 44-7/8-inch blades. Blade changes are quick and tool-free.

DeWalt DCS378B 20V MAX XR Mid-Size Bandsaw

The DeWalt DCS378B arrived as part of the newer XR mid-size bandsaw category. It sits between the compact ATOMIC models and the full-size DCS374B. This saw uses a brushless motor that delivers 535 MWO at 570 surface feet per minute (SFPM).

The cut capacity is 3-3/8 inches by 3-3/8 inches. That handles most common materials like conduit, pipe, and strut. DeWalt claims this saw can complete a cut through 12-gauge strut in just 5.1 seconds. That speed matters on commercial job sites.

A single 5.0Ah battery can power up to 120 cuts through 12-gauge strut. That is a full day of work for many electricians and plumbers. The saw uses 35-3/8-inch blades, which are shorter than the DCS374B’s 44-7/8-inch blades.

The overall weight is lighter than the DCS374B. This makes it a strong choice if you spend long hours cutting overhead or in tight spaces. The single trigger design offers straightforward operation. You squeeze and cut.

DeWalt DCS377B ATOMIC 20V MAX Compact Bandsaw

The DeWalt DCS377B belongs to the ATOMIC series. This is the smallest and lightest portable band saw DeWalt makes. It weighs just 6.6 pounds without a battery. That weight makes it a true one-handed cutting tool.

The compact size comes with a trade-off in cut capacity. The DCS377B handles material up to 1-3/4 inches. That covers conduit, threaded rod, small pipe, and thin-wall tubing. It does not cut large-diameter pipe or thick structural steel.

An integrated blade guard wraps around the exposed blade area. This guard lets you use the saw one-handed while keeping your other hand free to hold the material or brace yourself. The variable speed trigger and speed dial give you precise control for different materials.

This saw uses 32-7/8-inch blades. DeWalt offers several TPI options for these shorter blades. Electricians love this saw for cutting EMT conduit quickly. HVAC technicians use it for small ductwork and copper pipe.

Top 3 Alternatives for DeWalt Portable Band Saw

The Milwaukee 2529-20 M12 FUEL Compact Band Saw runs on the 12V M12 platform. It features Jobsite Armor Technology to protect against drops and debris. The compact size is ideal for tight workspaces. It competes directly with the DeWalt DCS377B.

The Makita XBP05R1B 18V LXT Sub-Compact Band Saw offers a 2-inch by 2-inch cut capacity. It runs on the Makita 18V battery system. The sub-compact form factor weighs under 7 pounds. This is a solid choice if you already own Makita 18V tools.

The DeWalt DWM120K 10 Amp Corded Deep Cut Band Saw is still a top pick for users who want unlimited runtime. The 10 Amp motor provides steady, constant power. The 5-inch deep cut capacity matches the cordless DCS374B. You never worry about batteries dying on a big project.

DeWalt DWM120K Corded Deep Cut Band Saw

The DeWalt DWM120K is the corded option in the DeWalt portable band saw family. It runs on a 10 Amp motor with variable speed control. The blade speed ranges from 100 to 350 SFPM. That range covers soft aluminum through hardened steel.

The cut capacity matches the cordless DCS374B at 5 inches deep cut. The saw weighs about 14.5 pounds, which is heavier than the cordless models. But you get consistent, full power on every cut. No battery fade. No recharging.

This model ships as a kit with a hard carrying case. The case holds the saw, blade, and accessories. It is a practical package for shop use and job site transport. The included blade is 44-7/8 inches long.

The DWM120K remains popular among fabricators and shop workers who stay near an outlet. If you cut metal all day at a workbench, the corded model offers better value than paying for batteries. The variable speed dial lets you fine-tune performance for each material type.

Cutting Performance Across All Models

Cutting performance depends on blade speed, motor power, and cut capacity. The DCS374B leads in maximum cut size at 5 inches. The DCS378B delivers faster blade speed at 570 SFPM. The DCS377B focuses on speed and convenience for small materials.

In real-world testing, the DCS374B cuts through 2-inch schedule 40 steel pipe in about 15 seconds with an 18 TPI blade. The DCS378B handles the same cut in a similar time frame. The compact DCS377B cannot fit 2-inch pipe because of its 1-3/4-inch capacity limit.

For unistrut and slotted channel, the DCS378B shines. DeWalt reports a 5.1-second cut time through 12-gauge strut. The DCS374B is close behind. Both models produce clean, straight cuts with minimal burr.

Blade choice matters. An 18 TPI blade works well for thin-wall material and tubing. A 14/18 variable TPI blade handles mixed-thickness material. A 24 TPI blade is best for very thin metals and clean finishes.

Battery Life and Runtime

All cordless DeWalt band saws use the 20V MAX battery platform. The DCS374B works with standard 20V MAX batteries and FLEXVOLT batteries. The DCS378B and DCS377B use standard 20V MAX packs.

With a 5.0Ah battery, the DCS374B delivers roughly 100 to 150 cuts through common materials like strut and conduit. The DCS378B reaches about 120 cuts per charge through 12-gauge strut. The lighter DCS377B typically exceeds 150 cuts because of its smaller motor and blade.

Larger batteries extend runtime significantly. A 9.0Ah FLEXVOLT battery in the DCS374B can nearly double the cut count. That makes a big difference on busy commercial jobs. Keep two batteries on rotation and you will rarely stop to recharge.

Battery charge time varies by charger model. A standard DeWalt charger takes about 60 to 90 minutes for a 5.0Ah pack. A fast charger reduces that to about 45 minutes. Plan your charging breaks around your workflow.

Build Quality and Durability

DeWalt builds their portable band saws for professional job site conditions. The housings use high-impact plastic and rubber overmold. The motor areas feature metal reinforcement. These saws survive drops from ladders and scaffolding.

The blade tracking system on the DCS374B and DWM120K uses a simple adjustment wheel. You can fine-tune blade position quickly. Proper blade tracking extends blade life and prevents the blade from slipping off the wheels.

Rubber tires on the internal wheels are a wear item. They last a long time under normal use, but they do need replacement after thousands of cuts. Aftermarket tire sets are easy to find and cost under $15. This is a cheap and simple maintenance task.

The trigger mechanisms on all models feel solid and responsive. The DCS378B and DCS379B (dual trigger model) use different trigger layouts. The single trigger DCS378B is simpler. The dual trigger DCS379B adds a safety lockout that some users prefer.

Ergonomics and Handling

A portable band saw is only useful if you can hold it steady for long periods. The DCS377B wins for pure ergonomics because of its 6.6-pound weight. You can use it one-handed above your head without fatigue.

The DCS374B weighs about 12.2 pounds bare. Add a 5.0Ah battery and it reaches roughly 15 pounds. That is manageable for most users, but long overhead sessions will tire your arms. The front handle and D-grip rear handle provide two solid contact points.

The DCS378B sits in a comfortable middle ground. It weighs less than the DCS374B but offers more cut capacity than the DCS377B. Many professionals call it the “Goldilocks” band saw because it hits the sweet spot for weight and performance.

All models feature rubberized grip surfaces that reduce vibration and prevent slipping. The hang hooks on the DCS374B and DCS378B let you stow the saw quickly. You do not need to set it on the ground or a workbench between cuts.

Blade Changing Process

Changing blades on a DeWalt portable band saw takes less than two minutes with practice. The DCS374B and DWM120K use a tool-free blade change system. You release tension, open the blade guard, slip the old blade off, and thread the new blade onto the wheels.

The DCS377B and DCS378B follow a similar process. The smaller blade size makes handling easier. You should always check blade tracking after installing a new blade. Run the saw briefly without cutting and watch the blade position on the wheels.

DeWalt sells replacement blades in three-packs. The DW3983 (18 TPI, 44-7/8 inch) fits the DCS374B and DWM120K. The DW3983C (18 TPI, 32-7/8 inch) fits the DCS377B and DCS378B models. Keeping a spare three-pack in your tool bag is smart practice.

Blade life depends on what you cut. Mild steel conduit and pipe are gentle on blades. Stainless steel, hardened bolts, and abrasive materials wear blades faster. Most professionals replace blades every 50 to 200 cuts depending on material hardness.

Price Comparison and Value

The DCS374B bare tool typically sells between $230 and $280. Adding a battery and charger pushes the total to about $350 to $400. The kit version (DCS374P2) with two 5.0Ah batteries and charger runs around $450 to $500.

The DCS378B bare tool prices in a similar range to the DCS374B. The DCS377B is the most affordable cordless option. It usually sells between $150 and $200 as a bare tool. That price point makes it an easy entry into cordless band saws.

The corded DWM120K kit often sells for $250 to $300. That includes the saw, blade, and carrying case. You save money by skipping batteries. For shop-based work, this is the best dollar-per-cut value in the lineup.

If you already own DeWalt 20V MAX batteries, the bare tool options offer the best value. You do not pay for batteries you already have. This is one of the biggest advantages of sticking within a single battery platform.

Who Should Buy Each Model

The DCS374B is for professionals who need maximum cut capacity in a cordless package. Plumbers cutting 3-inch and 4-inch pipe will appreciate the 5-inch throat. Ironworkers and fabricators benefit from the deep cut ability.

The DCS378B suits electricians and HVAC technicians who cut mid-size materials all day. The lighter weight and fast blade speed make quick work of strut, conduit, and small pipe. It is a strong all-around choice.

The DCS377B is perfect for tight-space work. If you spend time in crawl spaces, above drop ceilings, or on ladders, this compact saw is your best friend. Its light weight prevents fatigue during overhead cuts.

The DWM120K belongs in shops and fabrication areas. Any worker who has reliable access to an outlet should consider this model. You get full power, no battery limitations, and a lower entry price.

Maintenance Tips for Long Life

Keep your DeWalt band saw running well with a few simple habits. Clean the blade wheels after every heavy use session. Metal shavings build up on the rubber tires and affect blade tracking.

Inspect the blade tension before each use. A loose blade drifts during cuts and produces crooked results. A blade that is too tight puts extra stress on the motor and wheels. The adjustment mechanism on each model lets you set tension quickly.

Lubricate the blade lightly with cutting fluid or WD-40 when cutting thick steel. This reduces heat, extends blade life, and produces smoother cuts. Avoid excessive lubrication that could fling off during cutting.

Check the rubber wheel tires every few months. Look for flat spots, cracks, or glazing. Worn tires cause blade tracking problems. Replacement tires are inexpensive and available from DeWalt and aftermarket suppliers.

Final Verdict: Which DeWalt Portable Band Saw Is Best in 2026

Choosing the right DeWalt portable band saw depends on your daily cutting needs. The DCS374B is the best overall cordless model for heavy-duty work. It offers the largest cut capacity and runs on the proven 20V MAX XR platform.

The DCS378B is the best choice for users who want a balance of power, speed, and portability. Its 120-cut battery life and 5.1-second strut cuts make it a productivity machine on commercial sites.
