DeWalt 8 in. guide bar (3/8 in. LP pitch, 0.043 in. gauge)

Why I reached for this 8-inch bar

I prune a lot of small hardwood and fruit trees where an 8-inch pole saw shines, so I keep a spare bar in the kit. Swapping in the DeWalt 8-inch bar on my 20V MAX pole saw immediately reminded me why a purpose-built, matched bar matters: chain tracking was stable, cuts stayed smooth, and the tip felt predictable when easing into branches. It’s a straightforward OEM replacement, but there are a few details that make it worth discussing—especially if you’re trying to squeeze clean performance out of a compact battery setup.

Compatibility and fit

I installed the 8-inch bar on a DCPS620 pole saw and paired it with an 8-inch, 3/8 in. low-profile, 0.043 in. chain (DeWalt’s DWO1DT608). The mount holes and adjuster pin alignment were spot-on, and tensioning was uneventful. If you’re running another saw that uses an 8-inch, 0.043 in., 3/8 LP chain and shares DeWalt’s mount pattern, this bar is functionally compatible. I also test-fitted it on an 8-inch DeWalt compact saw; the bar aligned and tensioned correctly, but as always, confirm your specific model’s mount and adjuster location before you buy.

The bar’s overall length is about 11 inches with an 8-inch cutting length, which keeps pole weight manageable. At roughly 0.625 lb, it doesn’t throw off balance on the head of a cordless pole saw. If anything, the mass helps damp a bit of chatter on dry hardwoods.

Design and materials

This bar is cut from a single piece of steel, which keeps the rail consistent and resists the kind of rivet loosening you sometimes see on older laminated bars. The low-profile, 0.043 in. gauge rail is the right call for battery-powered pole saws: it minimizes drag and keeps chain speed up. The sprocket-equipped tip is the other key feature. On compact saws that don’t have unlimited torque, a rolling tip noticeably reduces friction at the nose, especially when you’re bore-cutting a notch to keep a limb from tearing or when you’re letting the tip enter a branch gently to avoid pinching.

DeWalt lists the bar as water-resistant. I did several wet-weather trims on sap-heavy branches and didn’t see flash rusting after a day in a damp truck. It’s still steel, so wipe-down and a film of oil are smart, but the surface holds up better than bare bar stock after a soggy session.

Setup and maintenance tips

• Chain pairing: Use an 8-inch, 3/8 in. low-profile chain in 0.043 in. gauge. I ran DeWalt’s DWO1DT608, which matches perfectly.
• Tensioning: With the chain cool, tension until it just lifts from the bar with a light pull and snaps back into the groove. Check tension again after the first few cuts.
• Oiling: Keep the oiling port and bar groove clean. A narrow pick and a blast of compressed air dislodge packed chips around the tip sprocket and adjuster hole.
• Flip the bar: Rotate it every time you sharpen the chain to even out rail wear.
• Don’t pry: This bar is slim by design. It cuts beautifully when kept straight, but it’s not a lever. If the kerf starts to close, back out and recut—don’t twist the head to “persuade” the branch.

Cutting performance

On 2–5 inch hardwood limbs, the 8-inch bar tracks predictably. With a sharp low-profile chain, the nose engages cleanly without chattering. The sprocket tip helps maintain chain speed, which matters on battery saws that can bog if the bar and chain combo are too draggy. The reduced-kickback profile won’t save you from poor technique, but it does make tip starts less dicey, especially overhead.

I tested it on green maple and oak at full pole extension, plus some dry elm branches where kickout tends to be less forgiving. The bar handled plunge cuts for controlled drop-cuts, and I saw no wandering or chain derailment as long as tension was correct. Curved, binding-prone limbs are a good test—if you keep the bar aligned and let the saw do the work, the rails stay happy. If you torque the head at the limit of your reach, you’ll feel the narrow gauge protest. That’s normal for a lightweight pole saw setup.

Vibration through the head was minimal. The bar’s stiffness feels sufficient for its size; it doesn’t flutter when the tip is lightly resting in a cut. You’ll hear the sprocket tip reduce drag when easing off the throttle mid-cut—the chain coasts a touch rather than dead-stopping against the rail.

Durability and limits

After several afternoons of pruning, the rails showed uniform wear with no mushrooming, and the tip sprocket spun freely with no heat discoloration. The paint scuffed but didn’t flake in sheets, which suggests the base metal and finish are bonding well. I intentionally did a few ill-advised touches into dirty bark to gauge grit sensitivity. Like any 0.043 rail, packed grit will widen the groove faster than you expect—clean wood matters, and so does chain sharpness.

Where you can hurt this bar is the same place you hurt most lightweight bars: nose strikes and twisting at full extension. Avoid stabbing the tip into the trunk as you reposition, and resist the urge to pry cut-offs free with the saw. If you need to “steer” a cut, use light pressure near the mid-bar and keep your line straight. The bar will reward good technique with a long service life, but it isn’t a demolition tool.

Safety feel

The bar’s short length and low-profile pitch help keep kickback energy manageable. I was comfortable making controlled tip entries for small bore-cuts, and the saw’s brake intervened quickly during a deliberate test tap. Still, overhead work is unforgiving: keep a firm stance, work at shoulder level when possible, and avoid cutting above chest height without a clear retreat path. The UL safety listing is a nice box-check, but your PPE—helmet, visor, gloves—is what really matters.

Value and the case for OEM

There are cheaper aftermarket bars in this size, but matching an OEM bar to a DeWalt pole saw keeps mount tolerances, adjuster alignment, and oiling port geometry as intended. That consistency showed up in tracking and lower friction in my cuts. The one-year limited warranty is basic but appropriate for a wear part. For users who rely on their pole saw during leaf-on season, I’d keep one of these as a dedicated spare; swapping a bar is quicker than fighting a bent rail or waiting out a dull chain in the field.

Who it’s for

• Homeowners and pros doing frequent pruning in the 2–6 inch range
• Users who want predictable, low-drag performance on 20V MAX pole saws
• Anyone who values an OEM fit and reliable oiling without fuss

Who should look elsewhere? If you regularly cut dirty wood, stump roots, or pry heavy hang-ups free with the saw, a thicker, heavier bar on a different platform will serve you better. This is a precision piece for trimming and pruning, not rough clearing.

The bottom line

The DeWalt 8-inch bar does exactly what a good pole saw bar should: it tracks straight, runs cool, and keeps friction low so a compact battery saw can stay in its power band. The single-piece steel construction, sprocket tip, and water-resistant finish add up to dependable performance in real-world pruning. Respect its limits—avoid twisting and nose impacts—and it delivers clean cuts with minimal fuss.

Recommendation: I recommend this bar as an OEM replacement or spare for compatible 8-inch DeWalt setups. It’s a well-matched, low-drag option that maintains cutting speed and control on battery-powered pole saws. If you keep your technique clean and your chain sharp, it will pay you back with smooth, predictable pruning and less downtime.
