DeWalt 16 in. 3/8 in. LP Pitch, 0.043 in. Gauge Guide Bar

Why I reached for this bar

Swapping a guide bar can breathe new life into a cordless saw, especially if you’re chasing cleaner cuts and better efficiency. I picked up the DeWalt 16-inch bar as a replacement for a well-worn stock bar on a 60V DeWalt saw and treated it like any other critical component upgrade: install it carefully, pair it with the right chain, and see if the cut quality and runtime justify the change.

Fit and setup

I ran the 16-inch bar on a DeWalt 60V saw (think the form factor of the DCCS670), pairing it with a 3/8 in. low-profile, 0.043 in. gauge chain. DeWalt’s matching narrow-kerf chain (DWO1DT616T) is the straightforward choice, and keeping pitch and gauge consistent is non-negotiable. The mount holes and slot alignment were on the mark, the tensioner engaged cleanly, and the chain tracked dead center on first spin.

A few notes from setup:

• The bar measures a touch under 20 inches overall (19.882 in.), with a nominal 16-inch cutting length.
• At 1.172 lbs, it doesn’t add noticeable nose-heaviness on a 60V chassis; balance felt neutral with a 9Ah pack on the rear.
• The 0.043 in. gauge is a narrow-kerf spec. That’s part of the appeal on cordless saws—less drag, faster chain speed under load, and often a bit more cut-per-charge.

If you’re replacing a different bar, confirm you have the correct pitch and gauge, and don’t assume your existing chain will fit. Drive link count is saw-dependent, so check your manual or the original chain packaging.

Design and build quality

This is a single-piece steel bar with a sprocket nose. That construction matters. Solid-body bars resist spreading at the rails and tend to stay straighter under heat. The sprocket tip reduces sliding friction at the nose, which helps both cutting efficiency and bar longevity.

Other design notes:

• Water-resistant finish: The coating held up to damp wood and a drizzly morning without rust flash or staining, which is ideal for outdoor storage in less-than-perfect conditions.
• Rail machining: The groove was uniform and clean out of the box, with no burrs. Chain sat snugly without binding.
• UL safety: It’s a UL-listed component, and the tip radius plus depth gauge‑friendly geometry contribute to lower kickback potential when paired with a compliant chain.

Nothing about the bar screams gimmick. It’s a straightforward, well-machined piece of steel that prioritizes durability and efficient chain handling.

In-use performance

I ran the 16-inch bar through a mix of fresh pine, seasoned oak, and a stack of storm-downed limbs that still had muddy bark. Here’s what stood out:

• Cutting feel: With a sharp 0.043 in. chain, the bar feeds smoothly and resists wandering. The nose tracks predictably in plunge cuts, and the narrow kerf really does help the saw keep chain speed in tougher material.
• Vibration and chatter: Chatter was minimal. The sprocket nose and rigid body keep the chain stable, especially in longer rips and when you’re cutting at full bar length.
• Heat management: After several back-to-back cuts, the bar was warm but not discoloring. Chain oil flow was adequate; I kept the oiler set on the higher side for dry hardwood.
• Kickback behavior: It’s not a magic shield—technique and a sharp, compliant chain still rule—but the tip profile and narrow kerf kept reactive forces manageable. Chain brake tests were uneventful and consistent.

Importantly, the bar didn’t feel like it was robbing the saw of power. Cordless saws live and die by efficiency. The reduced friction at the tip and narrow kerf complement the motor’s torque curve.

Battery life and efficiency

With an apples-to-apples chain in comparable wood, I saw a modest but noticeable improvement in cuts-per-charge versus a heavier-gauge bar and chain combo. Less drag at the nose and reduced kerf width show up as a few more crosscuts before the pack hits the low-voltage cutoff. It won’t double your runtime, but it does make the saw feel freer and faster in the cut—exactly what I want from a 16-inch setup on a cordless platform.

Maintenance and longevity

After a few weeks of regular use:

• Rails: Minimal mushrooming, and the groove walls stayed square. A quick touch with a bar dresser kept the edges crisp.
• Tip sprocket: Still spinning freely, no grit binding. Keep it clean and oiled; regular chain oil is sufficient.
• Finish: The water-resistant coating scuffed where the chain rides (as expected) but didn’t peel or rust around the slot or mount area.

Maintenance tips I found helpful:

• Match oil flow to wood: Dry hardwoods and longer cuts benefit from a richer oil setting.
• Flip the bar: Rotate it every chain swap to even out rail wear.
• Keep tension honest: Narrow-gauge chains can heat up and stretch if run too tight. Adjust after the first warm-up cut.

DeWalt backs the bar with a 1-year limited warranty. That’s reasonable for a component that lives in the line of fire.

Safety notes

• Stick with 3/8 in. low-profile, 0.043 in. chains. Mixing specs invites derailments and kickback.
• Verify your saw’s chain brake and oiling system are in good order before first use.
• Even with a lower-kickback profile, use a sharp chain, proper stance, and PPE. The bar helps; it doesn’t replace safe technique.

Limitations and compatibility quirks

Two caveats stood out:

• Chain availability: 0.043 in. narrow-kerf chains aren’t hanging on every hardware aisle. Plan to keep spares on hand, ideally the matching DWO1DT616T or an equivalent spec from a reputable brand.
• Platform specificity: This bar is intended for DeWalt’s 16-inch cordless models. If you’re running a different saw or a gas platform, verify the mount pattern and adjuster location before assuming it will fit.

Neither is a deal-breaker, but they’re worth planning around if you depend on your saw for daily work.

Who will appreciate this bar

• DeWalt cordless owners who want an OEM-fit 16-inch replacement that preserves the saw’s balance.
• Users cutting a mix of limbing, firewood, and light bucking who value runtime and clean tracking.
• Anyone who prefers the feel of a solid-body bar with a responsive tip on plunge cuts and bore starts.

You might look elsewhere if you need a heavier-gauge setup for consistently abrasive, dirty wood or if sourcing 0.043 in. chains is a headache in your area.

What I like

• Solid, single-piece steel bar that stays true under heat
• Sprocket nose reduces friction and helps runtime
• Predictable tracking with low chatter
• Water-resistant finish that shrugs off damp conditions
• Light enough to keep a 60V saw well balanced

What could be better

• Narrow-kerf chain availability can be spotty locally—stock up
• Platform-specific fit limits cross-compatibility with non-DeWalt saws

Bottom line and recommendation

I recommend the DeWalt 16-inch bar for anyone running a compatible DeWalt cordless chainsaw who wants reliable, efficient cutting with minimal fuss. It combines a rigid, single-piece build with a smooth-running sprocket nose and a narrow kerf that plays to the strengths of cordless powerheads. The result is cleaner cuts, steady tracking, and a modest boost in cuts-per-charge without compromising control.

The only real caution is chain availability. If you’re comfortable keeping a couple of matching 0.043 in., 3/8 in. LP chains on the shelf, this bar is a smart, durable upgrade that makes a 16-inch cordless setup feel sharp and ready for work.
