Woodworking Tool News - Forrest Sharpening / Repair Service

Forrest Manufacturing is providing in-factory sharpening and repairs of all makes of carbide-tipped circular saw blades.

A properly performing blade is essential to delivering a good, reliable cut and to achieving the positive results woodworkers and others expect from their blades. At a time when many companies don’t offer such services, Forrest Manufacturing continues to provide affordable, in-factory sharpening and repairs of all makes of carbide-tipped circular saw blades.


Forrest’s two-step sharpening process

There are several things that indicate a blade needs sharpening. For example, it may begin to feed slowly or cause chipping. Or it may run excessively hot and cause burning, especially when used on veneer or melamine.

Blade dullness often results from the abrasion caused by normal wear and tear or by resin buildup. In other cases, it can be caused by encounters with a nail or some other object. At other times, it may be caused by using the wrong blade for a given application. These factors can result in a microscopic wearing down of the blade’s carbide cutting edge, causing it to become shiny and rounded.

Whatever the cause of the problem, it can usually be corrected with Forrest’s in-factory sharpening. The process takes approximately 20 minutes per blade and utilizes automated, high-speed, diamond-grit machines with flood cooling. The first step is to sharpen the front of the tip by face grinding. The second step is to fine-finish the top cutting edge. Removing too much carbide can shorten blade life. So Forrest’s process removes only a miniscule amount—about .010” to .020”. As a result, a Forrest blade—if operated normally—can usually be sharpened 8 or 10 times over its life.


Expert blade repair

No matter how careful woodworkers or other craftsmen may be, it is possible they will need repairs to their saw blades at one time or another. For example, a saw blade may be damaged by a loose throat plate, by hitting a nail or some other foreign object, by moisture, by improper storage, by dropping, or even by a safety mechanism abruptly halting a rotating blade.

Fortunately, Forrest offers a full range of services to restore the operation and effectiveness of damaged blades. These repairs and adjustments include straightening bent teeth, replacing tips, re-grinding both sides of all teeth, providing extra top grind for extremely dull blades, opening gullets, tightening or enlarging the bore, welding or replacing steel shoulders, and more.

Although Forrest repairs all makes of circular carbide-tipped saw blades, most of the work requested on products produced by other manufacturers involves either sharpening or tip replacement. On the other hand, owners of Forrest blades are eager to take advantage of the full range of proprietary services that can often restore blade performance to something that approximates “as good as new.” Craftsmen appreciate that Forrest blades are precision-engineered from corrosion-resistant, super-strong C-4 micro-grain carbide. This alone provides up to 300% longer life between sharpenings than other carbide blades. And they like the fact that Forrest blades are hand-straightened to ensure perfect flatness and have exceptional perimeter concentricity and side runout of +/- .001.


Affordable pricing

Forrest Manufacturing is firmly committed to helping craftsmen and hobbyists maintain the life and performance of their carbide-tipped circular saw blades. For this reason, the company keeps sharpening and repair costs as affordable as possible.

Charges for sharpening vary according to the diameter of the blade and the number of teeth. For example, sharpening a carbide blade with a diameter up to 12” and with 32-40 teeth currently costs $21.50. A dado set with 14-24 teeth on the outside blade and 4+ tooth chippers currently costs $60.50. Rates for specific blades, dado sets, or other products (such as groovers/cutters, router bits, and planer knifes) can be obtained by contacting Forrest.

The cost of blade repair varies according to the task—and sometimes the time—involved. For example, the charge for straightening bent teeth is $2.50 per tooth. Replacing one tip costs $7. Replacing multiple tips is priced according to quantity. If the expense for repairs is going to run more than 60% of the cost of a new blade, Forrest will consult with the customer to determine the best course of action.

Forrest blades are available from fine-quality dealers, retailers, and catalogs, as well as direct from the factory. Customers can order Forrest blades in complete confidence because they come with a 30-Day, Money-Back Guarantee.
