270 owner reviews, more than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other power tools and workshop machinery we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The Delta 14-651 is a corded benchtop mortiser drawing power from a 110V supply and operating at 1720 RPM. That speed is in the classic range for hollow-chisel mortising, where a chisel and bit combination plunges into hardwood to cut clean, square mortises for traditional joinery. The 77-pound frame plants it firmly on any workbench and absorbs the vibration that lighter machines transmit to the operator.
At $630.63 this sits above the entry-level benchtop mortisers and below the premium Powermatic floor models. With 270 owner reviews at a 3.9-star average it carries the most substantial verified feedback of any mortiser in this group, which gives buyers more real-world signal than the zero-review alternatives. The rating just clears the 3.8-star quality threshold, indicating that most owners are satisfied but that some have reservations.
The listing does not publish chisel capacity, stroke length, or table tilt specs, so buyers comparing against the Powermatic models should verify the Delta's full specifications before committing at this price.
Pros
- 270 owner reviews provide the strongest buyer feedback pool in this mortiser group
- 77-pound frame delivers stability that reduces chatter and vibration during plunge cuts
- 1720 RPM is a proven speed for hollow-chisel mortising in hardwood
- 110V corded supply is compatible with standard single-phase shop power
- Delta is an established brand with wider parts and service availability than generic sellers
Cons
- 3.9-star average is the lowest rating in this mortiser lineup, suggesting some owner dissatisfaction
- At $630.63, it costs more than entry-level benchtop mortisers and chisel capacity is not published
- 77-pound weight makes it a permanent shop fixture; moving it between locations is impractical

Performance notes
The 1720 RPM motor is calibrated for hollow-chisel mortising rather than high-speed routing. The 77-pound machine sits at a weight class that resists movement during repeated plunge cycles, which matters for cut accuracy in hardwood. Corded 110V power provides consistent motor speed under load across a long session.
What buyers say
Owners highlight the machine's stability and its suitability for regular woodworking shop use. A segment of the 270-review pool points to fit-and-finish concerns or accessory compatibility issues, which accounts for the 3.9-star average falling below the typical 4.0 threshold seen in higher-rated mortisers.
