Popular Harbor Freight Mortising Machine Models
Some of the most popular mortising machine models available at Harbor Freight include:
| Model | Type | Price |
| HF-40005 | Pneumatic | $299.99 |
| HF-40010 | Electric | $149.99 |
| HF-40015 | Hand-Operated | $49.99 |
When selecting a Harbor Freight mortising machine, there are several key features to consider in order to ensure that you find the right tool for your project. The size and depth of the mortise, the type and size of the bit, and the machine’s ability to provide repeatable results are all important factors to consider.
Mortise Size and Depth
The size and depth of the mortise are critical considerations when choosing a mortising machine. A mortise that is too small may not provide enough room for the tenon, while a mortise that is too large may be difficult to achieve precise control over. On the other hand, a mortise that is too deep may be difficult to mortise accurately, or may damage the surrounding wood. It is essential to consider the size and depth of the mortise when selecting a mortising machine.
| Model Name | Max Mortise Size | Depth Capacity | Bit Size |
| HF-60012 | 3/4 inches | 3/4 inches | 1/4 inch |
| HF-60014 | 1 inch | 1 inch | 1/4 inch |
| HF-66010 | 1 1/2 inches | 1 1/2 inches | 1/2 inch |
Bit Size and Type
The type and size of the bit used with a mortising machine is also an important consideration. Different projects may require different types of bits, such as a straight bit or a combination bit. The size of the bit will also depend on the size of the mortise. In general, a smaller bit will be used for smaller mortises, while a larger bit will be used for larger mortises.
For example, if you are working on a project that requires mortises that are 1/4 inch deep and 1/2 inch wide, you will need to use a bit that is 1/4 inch in diameter. However, if you are working on a project that requires mortises that are 1 inch deep and 3/4 inch wide, you will need to use a bit that is 1/2 inch in diameter. It is essential to consider the size and type of bit when selecting a mortising machine.
Repeatability
Another important consideration when choosing a mortising machine is the machine’s ability to provide repeatable results. A mortising machine that is capable of producing repeatable results will allow you to achieve consistent and accurate mortises. This is particularly important when working on large projects or when you need to make multiple mortises in a short amount of time.
In order to achieve repeatable results, look for a mortising machine that has features such as adjustable depth stop, precision bit alignment, and a sturdy frame. These features will allow you to make precise adjustments and achieve consistent mortises.
