In this dewalt benchtop planer review, we examine the DW734 model. This machine is defined by its 15-amp motor and 12-1/2-inch cutting width. It is a corded benchtop planer designed for substantial material removal. The unit weighs 80 pounds and measures 24 inches in length. Its 15-amp motor drives the cutterhead at 10,000 rpm. This speed helps deliver a fine finish on hardwoods. You get three knives for cutting. The machine handles cuts up to 2 inches deep. It is built for users who need power and width in a portable format.
What stands out
- 15-amp motor delivers 20,000 rpm for deep cuts in hardwoods.
- Three-knife cutter head runs at 10,000 rpm for 96 cuts per inch.
- 12-1/2-inch cutting width accommodates wide boards.
- Disposable, reversible knives offer 30% more knife life.
- Four-column carriage lock reduces snipe and movement.
Who it fits
Good fit for
This planer suits woodworkers who frequently process wide boards up to 12-1/2 inches. The 15-amp motor and 2-inch cutting capacity help those removing significant material from hardwoods. The extra-long infeed and outfeed tables support longer pieces, reducing snipe. If you need a portable unit with a powerful motor and wide capacity, this model fits your benchtop setup. The turret depth stop helps you return to frequent settings quickly.
Who should skip it
You should look elsewhere if you need a planer for boards wider than 12-1/2 inches. The 80-pound weight makes it less ideal if you move the machine often. If you require a thinner maximum cut depth than 2 inches, this might be overkill. Users needing a cordless tool will not find one here, as it is corded. Those wanting a very compact footprint under 17 inches wide should consider smaller models.
Verdict: The DEWALT DW734 offers a powerful 15-amp motor and wide 12-1/2-inch capacity for serious benchtop planing. Its three-knife head and carriage lock provide a fine, stable finish for hardwoods.
Key specs explained for planer
Motor Power: 15-Amp
A 15-amp motor delivers substantial torque for consistent operation. This power level allows the machine to handle deeper cuts in dense hardwoods without stalling. You benefit from reliable performance during heavy stock removal tasks. When comparing benchtop planers, higher amperage generally indicates better ability to maintain speed under load, ensuring smoother results on tough materials.
Cutting Width: 12-1/2-Inch
This width determines the maximum board size the planer can process in a single pass. A 12-1/2-inch capacity accommodates most standard lumber widths found in home workshops. It allows you to plane wide boards without needing to joint edges first. When shopping, verify this measurement against your typical project dimensions to ensure compatibility with your stock sizes.
Blade Count: 3
The cutter head features three knives, which influences surface finish quality. More blades generally produce a smoother surface by reducing the distance between cut marks. This configuration helps minimize tear-out on figured woods. When comparing models, note that three-knife heads are standard for portable units, offering a balance between finish quality and maintenance simplicity for general woodworking.
Cutterhead Speed: 10,000 rpm
The cutter head rotates at 10,000 revolutions per minute. This speed, combined with three knives, results in 96 cuts per inch. Higher cut density creates a finer surface finish that requires less sanding. When evaluating planers, this metric helps predict the final wood texture. Faster cutter heads generally yield smoother results, reducing the need for additional finishing steps on your projects.
Design and build overview
The DW734 is a heavy benchtop planer weighing 80 pounds. Its dimensions are 24 inches long, 17 inches wide, and 21 inches high. This substantial footprint suggests it is intended for a dedicated workspace rather than temporary setups. The black and yellow finish is typical for the brand. The unit uses a corded power source, requiring a nearby outlet for operation.
According to the listing, the machine features a four-column carriage lock. This design choice drastically reduces movement that typically causes snipe during planing. You get more consistent results on your workpieces. The infeed and outfeed tables are extra-long, providing 33-1/2 inches of material support. This layout helps you feed longer boards smoothly without them tipping or catching unevenly.
Controls include a material removal gauge and an extra-large thickness scale. These components allow you to set accurate cuts with every pass. A turret depth stop lets you return to your most frequently used depths quickly. This saves time when you are making repeated adjustments. The three-knife cutter head is a core part of the build. It spins at 10,000 rpm to deliver a fine finish. The knives are disposable and reversible, which extends their life by 30 percent. This design makes knife changes fast and easy for you.
Setup and daily operation guide
Setting up the DW734 involves positioning a heavy unit. At 80 pounds, it requires a sturdy bench. The dimensions are 24 inches long, 17 inches wide, and 21 inches high. You need adequate floor space for the extra-long infeed and outfeed tables. These tables provide 33-1/2 inches of material support. This length helps stabilize boards during feeding. The four-column carriage lock reduces movement. This feature minimizes snipe by keeping the carriage steady. You secure the unit to your workbench before powering it on. Daily use begins with checking the material removal gauge. The extra-large thickness scale allows for accurate cuts. You adjust the depth using the turret depth stop. This mechanism lets you return to frequently used depths quickly. The planer handles wood up to 12-1/2 inches wide. It removes up to 2 inches of material in total capacity. The 15-amp motor runs at 20,000 RPM. The cutter head spins at 10,000 RPM. This speed creates 96 cuts per inch. The result is a fine finish on hardwoods. You use disposable, reversible knives for maintenance. These knives offer 30% more life. Changing them is fast and easy. The machine requires a standard power outlet. It is corded, so you manage the cable during operation. The black and yellow color scheme is standard for the brand. You keep the workspace clean to ensure smooth operation. The design supports consistent, heavy stock removal tasks.
Before you buy this planer
This DEWALT model is a heavy, high-capacity tool. It weighs 80 pounds. You need a solid bench to support it. The 12-1/2-inch width handles standard lumber. You must check your material size against this limit. The 15-amp motor requires a dedicated circuit. Do not plug it into a standard outlet shared with other heavy tools. The unit includes reversible knives. You will need to buy replacements eventually. Keep spare blades on hand. The four-column carriage lock reduces snipe. You should still make test cuts on scrap wood. This machine fits well in a dedicated shop. It does not fit in small garages. Compare it to lighter models if space is tight. The 3-knife head provides a fine finish. You may need to adjust the dust port for your shop vacuum. Ensure your vacuum hose fits the port diameter. This planer suits serious woodworkers. It is less suitable for casual hobbyists with limited space.
Check before you buy
- Verify your workbench can support 80 pounds.
- Check if your electrical circuit handles 15 amps.
- Confirm your lumber width is under 12-1/2 inches.
- Ensure you have space for the 24-inch length.
- Buy spare reversible knives for future maintenance.
