A saw is a piece of toughened steel with teeth cut into one edge and a wooden or plastic handle. In some form or other, saws have been one of the principal woodcutting tools for thousands of years. The different types of saw for different jobs can roughly be divided into three main groups:
- saws for cutting along the grain of wood - rip saws
- saws for cutting across the grain of wood - cross-cut saws
- saws for cutting curves or special shapes, such as bow saws and fret saws. There are also special-purpose saws for cutting wood while it is still on the tree - pruning saws, for example.
Miter Saw Blade
Saws differ in the size and shape of the blade, and the size, shape and number of teeth they have. Rip teeth, which are designed for cutting down the grain of wood, work like small chisels. The front edge of each tooth is more or less perpendicular to the saw edge and the back edge slopes at about 30 degrees. If saws with teeth like this are used to cut across wood grain, they tend to tear the fibres and leave a jagged edge. Rip teeth are generally straight-sharpened the tip of each tooth is perpendicular to the cutting line. Cross-cut teeth, which are designed for cutting across wood grain, generally slope back rather more and are usually cross-sharpened the teeth are sharpened at an angle to the saw so that the outside edge of each tooth is pointed. Cross-cut teeth tend to cut through the wood fibres rather like a knife. Fleam teeth slope back even more than cross-cut ones and have symmetrical points. They cut equally well on the push and pull strokes.
Saw teeth are usually set teeth are bent slightly outwards from the blade, alternately in each direction, so that the width of the slot cut by the saw is greater than the width of the blade. This prevents the saw jamming in the slot when cutting and lets you change the direction of the cut slightly during sawing. An even set is essential: badly set saws tend to wander.
For years, saw blades have been made from hardened steel which has been tempered to reduce the hardness (and increase the toughness) so that the blade wears well but is still soft enough to be sharpened with a file. More recently, however, saws have been introduced which have 'hardpoint' teeth the tips of the teeth are hardened to reduce wear. Saws with hard-point teeth can have several times the life of a conventional saw, but they cannot be sharpened by conventional methods and they are much more easily damaged when they meet a nail in their path.
There are, confusingly, two systems for describing the number of teeth a saw has - both are still based on imperial measurements. The first method records the number of complete teeth in an inch length of blade. The second method states the number of tooth points in an inch, starling on a point and including this in the count. The two methods can be confusing since a saw with eight points per inch actually has seven teeth per inch. The second method is the most widely used and the terminology is often shortened to talk about an eight-point saw, for example. Saws with large teeth generally cut faster but leave a rougher edge than saws with small teeth.

This 10" Perma-Shield coated blade gives new life to underpowered saws and produces smooth crosscuts in hardwoods, softwoods, and moldings. The coated blade pulls 1/3 less on the saw, which translates into 33 more cutting power. The thin kerf blade (.090) removes less material than standard carbide blades, thus requiring less horsepower to produce equally good results. 5/8" arborChristmas Sales Freud LU88R010 10-Inch 60 Tooth ATB Thin Kerf Crosscutting Saw Blade with 5/8-Inch Arbor and PermaShield Coating Specifications
The Freud Difference
Freud manufactures some of the most innovative, technologically advanced saw blades in the world. To ensure that the highest quality products meet the toughest design standards, Freud owns and operates six manufacturing facilities in Western Europe. Freud is one of the few manufacturers of woodworking tools in the world that produces its own MicroGrain carbide with titanium, called TiCo -- a combination of titanium and cobalt. Freud develops different types of carbide for each application to maximize the cutting life and performance of the tool; and Freud also operates one of the most modern product development research centers in Europe. By overseeing the entire manufacturing process from start to finish, Freud guarantees some of the highest quality, most advanced products in the industry.
About Freud Industrial Blades
Freud’s industrial series blades were designed for the serious woodworker. Available in a variety of styles for different applications, LU blades feature thick carbide tips, precision-tensioned bodies found in every Freud quality blade. Some LU blades include a red Teflon coating that helps reduce friction, heat build-up, and gumming -- which prolongs the life of the blade.
About this Thin Kerf Crosscutting Saw Blade
This blade gives new life to underpowered saws and produces smooth crosscuts in hardwoods, softwoods and moldings. Coated blades pull 1/3 less on the saw, which translates into 33-percent more cutting power. This thin kerf blade removes less material than standard carbide blades, thus requiring less horsepower to produce equally good results. The "fusion" tooth design gives glass smooth side finishes as well as a chip-free top and bottom during both ripping and crosscutting applications. Perma-Shield permanent non-stick coating reduces friction, protecting this thin kerf saw blade against corrosion, gumming and pitch build-up. With laser-cut construction made from high-strength steel, this blade is built for long life and precision. Pre-tensioning assures that the blade will remain flat through the shocks from cutting and stresses from turning at high speeds, and its anti-vibration reed design eliminates all vibration and produces the cleanest cuts possible, making the use of a stabilizer unnecessary.
Applications
This exceptional blade rips and crosscuts wood, chip board, plywood, and laminate -- but it is not recommended for ferrous metals or masonry. This blade is ideal for crosscutting with a fine finish, while using an underpowered saw.
Warranty
This blade is covered by Freud's limited lifetime warranty.
