A Woodworker's Perspective on the Powermatic 15HH-15S Planer

Having used the Powermatic 15HH-15S Planer in my woodworking shop for several months now, I've come to appreciate the subtleties and strengths of this machine. My work involves creating custom furniture pieces, and precision is a critical factor that can significantly impact the final product. Here are my thoughts on how this planer fits into daily operations and some of the benefits it has offered.

Day-to-Day Use and Performance

From the first day, setting up the Powermatic planer was a straightforward process, which was a relief. Adjusting the tables and getting the machine ready for its first job was less cumbersome than expected, given its size and the complexity often associated with industrial tools.

The helical cutterhead, with its 74 carbide knife inserts, was something I was particularly eager to test, and it did not disappoint. The quality of the finish on hardwoods, which are a staple in my workshop, has been noticeably smoother than what I achieved with previous planers that used standard cutterheads.

One feature that stands out for daily use is the dual-speed gearbox. It allows for quick adjustment between different types of cuts, which is invaluable when I need to switch between rough dimensioning and fine finishing. This flexibility has been a significant time saver.

Handling a Variety of Wood Types

My projects often require working with a variety of wood types, from soft pines to hard maples.
The Powermatic planer handles these differences with ease, a testament to its robust motor and versatile cutterhead. Adjusting the cutting depth according to the wood hardness helps in minimizing tear-out and ensures a consistent finish across different materials.

This adaptability is crucial for maintaining quality and efficiency, especially when deadlines are tight.

Precision and Adjustability

The precision of the planer is another aspect that significantly impacts my daily work. The large cast iron handwheel makes fine adjustments straightforward, allowing me to dial in exact thicknesses without too much back and forth. This precision is particularly beneficial when I'm working on custom fittings or components that need to match precisely in an assembly.

Workflow Integration

In terms of integrating the planer into my existing workflow, the built-in casters have been a game changer. Despite its hefty size, I can move the planer around the workshop to accommodate changes in the workflow or to make space for larger project assemblies.

This mobility helps in optimizing shop space, which is often at a premium.

Noise Level and Safety

The reduced noise level due to the helical cutterhead is not just a comfort perk; it contributes to a safer work environment. In a workshop where multiple machines run simultaneously, being able to hear safety alarms and calls from coworkers is crucial. And, the magnetic safety switch on the planer provides an extra layer of security, ensuring that the machine won't accidentally start up—a feature I now consider essential.

Efficiency and Dust Management

The efficiency of the dust collection system has also impressed me. Keeping the workshop clean not only creates a more pleasant working environment but also reduces the risk associated with airborne dust.

The 4" dust port on the Powermatic effectively pulls away chips and dust, which is particularly noticeable when handling larger boards that generate more debris.

Practical Benefits and Drawbacks

The large cast iron table and extension wings provide ample support for larger pieces of wood, which is a great help during larger projects. However, it's worth noting that the size of the machine requires a considerable amount of space. For those with smaller workshops, this might be a limitation.

Another minor issue is the initial investment. The Powermatic 15HH-15S Planer is at the higher end of the price spectrum, which might be a consideration for hobbyists or smaller operations. But for professional environments where quality and reliability are paramount, the investment makes sense.


The Powermatic 15HH-15S Planer has proven to be a reliable, high-performance tool in my workshop.
It's well-suited for woodworkers who prioritize quality finishes and operational efficiency. While it comes with a higher price tag and requires a bit of space, the benefits in terms of durability, safety, and performance are clear.

For anyone serious about woodworking and looking to upgrade their equipment, I would recommend considering this planer. It's a solid choice that should meet the needs of most professional users without going overboard.

The Powermatic 1791213 Model 15HH-15S Planer stands out as a premier choice, boasting a range of features that cater to professionals and hobbyists alike. This review will delve into the specifics of its design, features, and performance, helping you determine if it's the right addition to your workshop.


The Powermatic 15HH-15S Planer is equipped with a helical cutterhead, which is a significant upgrade over traditional straight knife cutterheads. The helical design includes 74 four-sided indexable carbide knife inserts that produce a smoother, quieter cut and a finer finish. This not only enhances the quality of the work but also reduces the noise level in your work environment.

A powerful 3HP TEFC (Totally Enclosed Fan-Cooled) motor drives this machine, offering ample power to handle both softwoods and hardwoods with ease. Safety is paramount in any power tool, and here, a magnetic switch controls the motor, providing a reliable safety feature that prevents unintended startups.

The planer features three V-belts that efficiently transfer power from the motor to the cutterhead, ensuring consistent performance. The infeed and outfeed rollers are designed to optimize the handling of materials. A serrated steel infeed roller and a smooth steel outfeed roller support a maximum depth of cut of 1/8 inch, facilitating trouble-free operation through various wood types.

Additional features include a large cast iron handwheel for quick and easy table adjustments and built-in lockable casters on the one-piece welded steel stand, which enhance mobility within the workshop.

The planer also includes a large, precision ground cast iron table and extensions that provide ample support for larger workpieces.
