DEWALT DW734 Benchtop Planer Review — 12-1/2″ 15-Amp Three-Knife

What the Research Shows

The DEWALT DW734 is consistently identified across independent published assessments as one of the most respected benchtop planers in the woodworking category, with multiple long-term video reviews spanning several years of ownership reporting high reliability and consistent satisfaction. Published manufacturer specifications confirm a 15-amp motor, a three-knife cutter head with disposable double-sided knives, a maximum cut depth of 1/8 inch per pass, and capacity for boards up to 12-1/2 inches wide and 6 inches thick. Independent tool comparison publications specifically recommend the DW734 as a step-up alternative to base-tier benchtop planers for buyers prioritizing durability and finish quality.

At approximately 80 pounds, the DW734 is built for stability during operation while remaining portable via built-in handles, with optional mobile base carts available separately. The three-knife cutter head design is a key differentiator from two-knife benchtop planers — published assessments consistently attribute the DW734’s smoother finish quality to the additional cutting knife, which reduces the cutting load per knife edge and produces more cuts per revolution.

Cutting Performance & Finish Quality

Published assessments across multiple independent reviewers consistently praise the DW734’s finish quality and dimensional accuracy as standout attributes relative to two-knife benchtop planers at lower price points. The three-knife cutter head produces a noticeably smoother surface finish that published assessments describe as requiring less post-planing sanding than two-knife alternatives. The disposable double-sided knives can be flipped once for a second cutting edge before replacement — published pricing data indicates replacement sets cost approximately $40–$50, a routine maintenance expense confirmed across multiple independent sources.

Long-term published video reviews spanning several years of ownership report consistent thickness accuracy and reliable performance without frequent fuse resets or motor issues — a notable point of differentiation from published assessments of lower-tier competing planers. As with all benchtop planers, proper infeed and outfeed board support is necessary to minimize snipe; published assessments note this remains a factor even on the DW734, though several reviewers describe the machine’s snipe as manageable with correct technique.

Build Quality & Design

The DW734’s approximately 80-pound weight and robust table construction are consistently cited across published assessments as contributing to the machine’s stability during cuts and its reputation for long-term reliability. The dust collection hood integrates effectively with shop dust collection systems according to multiple published assessments, and the infeed/outfeed tables fold down for more compact storage — though published sources note the tables cannot fold with the dust hood attached, a minor design tradeoff. The large on/off switch is highlighted in published reviews as a meaningful safety feature, and the depth gauge with adjustment knob is described as accurate and easy to use for setting precise cut depths.

Where It Falls Short

Research and published assessments identify legitimate drawbacks. Multiple independent video and forum assessments describe the DW734 as notably loud during operation — hearing protection is universally recommended by published reviewers. Changing the three-knife cutter head’s knives is described in published forum discussions as more involved than simpler two-knife systems, though the disposable, reversible design reduces how often this is necessary. Preset thickness stops are limited compared to some competing models, meaning most thickness adjustments are made via the depth gauge rather than fixed-position stops. Published forum feedback includes at least one long-term owner report that the thickness setting can drift slightly over years of use, though this did not prevent that owner from continuing to use and generally recommend the tool. The dust collection hood design is described by some published reviewers as somewhat cumbersome relative to newer competing designs. At approximately 80 pounds, moving the DW734 without a mobile base requires more effort than lighter benchtop planers.

Value Assessment

At a price point roughly $50–$100 above base-tier two-knife benchtop planers, published assessments consistently conclude the DEWALT DW734 justifies the premium through its three-knife finish quality, dimensional accuracy, and multi-year reliability record. Independent tool comparison publications specifically recommend the DW734 as an upgrade path over lower-tier alternatives for buyers who plan regular or serious woodworking use. Multiple published long-term ownership reviews spanning years of use report continued satisfaction and reliable performance, reinforcing DEWALT’s reputation for durability in this category. Research and independent published assessments consistently position the DW734 as one of the best benchtop planers available for serious hobbyists, remodelers, and small shop owners who need consistent, professional-quality results.
