There are some impressive features this jointer possesses.

Some of which will allow you to complete more woodwork projects with less fuss. Read on to find out these features.

Quick Set Knives

The Jet 708457DXK comes with a set of already-installed knives on the cutter blade. The knives are perfectly made to smoothen wood surfaces of up to 6-inches.

With this, you will need little or no adjustment.

Even better, the knives have a quick-change system. This way, you can easily fix another knife incase the blade of old ones become blunt.

Dust Chute

It’s bound to get a bit messy when working on wood. Specks of dust are bound to fly off. This is the advantage premium jointers have overhand planers.

The Jet 708457DXK, in particular, features a dust chute. This is where the remains of woods being worked on are collected.


Power and Performance

The Jet 708457DXK has a motor that produces 1 hp of energy. The motor produces enough power for the jointer to work on woods of different thicknesses at a stretch.

You can use it on mahogany, walnut, or pine without the engine stuttering midway.

The jointer is quite heavy, but you won’t need to worry about transportation since it will be rooted to a spot.

Also, this jointer is powered by electricity and not the battery. What this means is that it minimizes recurring costs, and the one-push button provides an easy start.

Overall, the performance of the Jet 708457DXK suits its price tag. You can use it to smoothen both the face and edges of wood with great precision.

It creates a straight and smooth surface during tedious woodworking projects.

Ease Of Usage

Being perfect with a hand planer doesn’t mean you will instantly become good with a jointer.

A jointer operation is much more advanced and would require a few practices under an expert’s watchful eyes.

Also, the tables of the jointer have to be adjusted depending on the size of the wood. Luckily, the tables come with a mounted wheel that allows adjusting their height easily.

Overall this jointer isn’t hard to operate. Once you know all the nitty-gritty involved, it only takes a few efforts before you start operating like a professional.


Ease Of Maintenance, Repairs, & Warranty

The manufacturers recommend the proper maintenance of blades and screws.

The blades should be cleaned with a solvent to eliminate any particle which might cause friction. Also, there’s no need to use the blades when it gets dull.

The screws, on the other hand, should be lubricated with a light coat of grease. The same applies to the outfeed gibs to allow free movement of the tables.

Jet tools, including the Jet 708457DXK, are covered by a 5-year warranty. This means if one or more parts of this tool become faulty and need professional repair, you can reach out to the company’s technical team.

The 5- year warranty period only applies to household use ; commercial users only get a 2-year warranty.

Price Of the Jet 708457DXK Jointer

This Jointer from Jet tools has a high price tag.

Compared to smoothing woods with a hand planer, this is a better alternative.

Not only is it easier to smoothen the wood surface with this, but it also gives better precision and takes fewer hours to get the job done.

Also, each of its parts is covered by a 5-year warranty. This is an indication that you will be using it for a very long time.


Pros and cons of the Jet 708457DXK Jointer

It’s hard to imagine any area this tool is lacking. However, there are a few loopholes we’ve observed while using the tool, and we’ve mentioned them below.


  • Easy to use
  • One-push button for easy start
  • Runs on electricity, minimizing recurring cost
  • Chute box for collecting wood chip


  • Blades get blunt easily
  • 6-inch bed relatively small for professional use


Who Should Buy the Jet 708457DXK ?

If you’re just getting started with woodworking, our bet is that you won’t need this jointer. You’re better off learning how to use a planer at first.

However, once your hand skill level improves along with your workload, you can consider a jointer.

This is because jointers provide more precision, control, and faster finish.

Our Recommendation

The Jet 708457DXK is quite pricey but is on a different level to planers, which is what makes it even more desirable.

Also, its sturdy design signifies that it’s built to last for a long time, but one feature that stands out is the presence of a dust chute. With this, your workplace doesn’t get messy with wood chips.
