 Band Saw Basics
All About Blades
A circular saw may be portable, and a jig saw may be able to make a plunge cut into the center of a piece of wood, but only a band saw can produce a truly finished piece of wood. As the thin steel blade zips along at upwards of 2,000 feet per minute, the wood it parts emerges with a clean edge, as if it's been polished with fine-grain sandpaper. |
 A band saw gets its name from the blade itself, a giant loop that's stretched between two or three wheels and pulled through a small hole in a cutting table. Its blade is thin--far thinner than that of a circular saw--and can cut not only straight lines, but also graceful curves. This makes band saws a favorite among everyone from boat builders to furniture makers. With the right blades, these versatile saws can cut plastic and metal as well as wood. |

Heft |
| You can't just toss a band saw into your toolbox the way you can a circular saw. The biggest floor models, which can cut massive beams lengthwise, weigh nearly a ton. There are more modest versions that sit on special stands, but even smaller bench-top versions, which might be considered portable, would be hefty to tote. |
Measurements |
 Regardless of their overall dimensions, band saws are classified by the diameter of the wheels that hold their blade in place. That dimension is slightly greater than the one that really counts: throat capacity. Measured by the distance between the blade and the throat--the supporting post that connects the top and bottom wheels--throat capacity determines the maximum width of board the saw can handle.
The depth of the cut that can be made is determined by another measurement altogether--namely, how far the upper blade guide can be maneuvered above the table. Bench-top models might eke out a cut just over 3 inches deep, those on stands might go to 6 inches, and giant floor models may be able to cut 12 inches or more. |
Horsepower |
 An underpowered tool will labor under the effort of the work and cut slowly, resulting in burns in the wood from the accumulating friction. To avoid this, you need a saw that has the appropriate horsepower for the job.
For instance, if you're cutting through 3 or more inches of hardwood, you'll need a saw with at least a 1/2 horsepower motor. To make cuts of up to 6 inches deep, go with a 3/4 horsepower motor. To saw beams, you'll need a giant machine with about 3 horsepower. |

Size |
Blades come in a nearly uniform thickness, but they vary greatly in width.
- Narrow 1/8-inch blades can cut tight curves without twisting and breaking.
- Blades of 1/4 inch are the most versatile; they're narrow enough to cut curves and wide enough to handle straight cuts quickly.
- A 3/4-inch blade can still cut curves with a decent 5-inch radius.
- Larger blades of up to 2 inches or more are strictly for
straight lines. These cut fast and straight, and won't twist.

Tooth count |
 The fewer teeth a blade has per inch, the faster it will cut. For this reason, many-toothed blades should be used for thin stock; blades with fewer teeth work better on thick boards.
Blades for sawing beams, for instance, might have only two or three teeth per inch, while a blade for thin scrollwork can have 20. The most popular blades among woodworkers have between 4 and 10 teeth per inch. |
Material matters |
Blades come in a variety of materials:
- Steel Blades: The least expensive. Although they work well with ordinary wood, they become dull when used on glued woods or plastic, and they won't cut steel.
- Bimetal Blades: Designed to handle the strain of cutting metal; their teeth are made of high-speed durable steel.
- Carbide Blades: Pricey, but they stay sharperlonger than ordinary steel blades. They should be used only on wood, not metal.
