A Little Background

A mortiser is a helpful tool for any woodworker. Its main objective is to cut holes that are square in shape so that wood working will be simplified. Traditionally, mortising is done by the hand and this can take a lot of time and have a loss for accuracy when being done repetitively, whereas a machine can do the job just fine without getting hand fatigue or losing accuracy. A mortiser nowadays depends on machinery so that the job will be done in fewer amounts of time and with less effort.
Mortisers use chisels and bits to help drill holes perfectly on wood without messing up the wood material. When you use regular drills with super high speeds, it might accidentally break the wood or lumber and this is why mortisers have special speeds that are not too low and not too high. The speed of a mortiser is usually just right for wood material and specifically made for wood working. This is because it must meet the demands of woodworkers and it should adhere to the standards of common lumber and wood works.

How We Picked

A mortiser with a great speed at RPM is a good machine. Typically, you will always get a slow speed mortiser because wood cutting is not really that much of a hassle and trouble as compared to drilling holes on metal and such. Mortisers are typically made for wood and not hard materials such as metal.
You must know the horsepower of the mortiser. You will mostly get mortisers that run from 1/2 HP to 1 HP depending on their price features and size. The more horsepower it has the more power it can give you and the faster you can do your wood working job.
The mortiser should also come with the required accessories for mortising, such as bits, chisels, etc. Usually, the bits that come with any mortiser vary in length and measurements. These accessories are crucial when it comes to operating the mortiser and it will also help if you have multiple sizes of bits and chisels so you can choose ones that are more fitting for your job and can adjust accordingly.
The depth stop of a mortiser is crucial to making perfect cuts. This is a safety feature and a precision feature as well so that your mortising operation will run smoothly and surely. More often, you can assign the depth stop a value to meet your operation needs, which is very helpful.
Adjustability is a big game changer in any mortiser so a rack and pinion system must be present. In fact, there are mortisers out there with totally flexible parts but this is just a big plus point. You will most likely find adjustability in every mortiser out there so that you will not run into problems with any kind of wood size and thickness. In fact, some mortisers can be used for door installations.
Flexibility is a plus point if you have a mortiser that has a lot of tiltable and twistable components. Table top mortisers or bench top mortisers can also have flexible parts that rotate and tilt whenever and wherever you like it. In some cases, these mortising machines can be a bit pricey but if you really want precision and work place flexibility then these mortisers are very highly recommended for you.
A sturdy base must be included in the mortiser, particularly a cast iron one for durability. A mortiser is built to last for years to come and this is why they must be encased in a durable housing and a sturdy cast iron base at the very most to protect their inner components. More commonly, the price is a decisive factor when it comes to durability. Even if you save tons of dollars on a cheaper model, it will not be as durable as an expensive one and will always have flaws with it.
A mortiser that does not produce a lot of noise is something to look forward to. This is measured in decibels (dB) and is also a decisive factor on the operation of any mortiser. If you work on a neighborhood shop, you would not want to disturb the neighbors. What’s more, since power tools are generally noisy, it really helps to protect your ears from high volume damage by using a low noise level mortiser for your daily job or DIY projects.

Other Frequently Asked Questions

Q: What exatly is a mortiser and what does it do?
A: According to the information laid down by Wikipedia a mortiser is something that woodworkers need to shape or cut holes, particularly rectangular and square holes, on wood and similar lumber. Mortisers are needed for precision work and to speed up wood working in general. Mortisers are unlike drills that are often used for metal and only make circular holes. Mortisers are made to cut square holes that are specifically used for wood working.

As a matter of fact, there are many kinds of mortisers for you to choose from. However, the most commonly used are the chain mortisers in which the work piece is clamped to the frame. On the other hand, horizontal mortisers and square chisel mortisers are other types of this kind of machinery. Whichever mortiser you chose, most of this machinery can cost a lot of bucks so they are only typically ideal for those who own a business or a shop or work in the industry of woodworking and such.

Q: Any tips on using a mortiser?
A: According to Woodworkers Guild of America , it is important that you know the parts of the mortiser. For the basics, the hollow chisel is the one that creates a square hole while the auger spins within the hollow chisel to make a perfect and clean cut.
