Wood-Mizer Blade Spotlight: DoubleHARD

Field tested in demanding sawing applications throughout the world, Wood-Mizer DoubleHARD blades are the flagship and workhorse sawmill blade that sawyers have trusted for decades. DoubleHARD blades earned their name because Wood-Mizer starts with a high-quality alloy steel and induction hardens the tooth tip, resulting in a durable and reliable blade that delivers twice the toughness and twice the sharp life compared to standard carbon blades.

There’s a reason why DoubleHARD is one of the industry’s most popular sawmill blade. DoubleHARD blades are tough, durable, and won’t chip or wear down prematurely. Each tooth is precisely set by computer-controlled equipment and completely profile ground tip to tip using super abrasive CBN grinding technology to ensure the highest quality blade performance for any type of sawing application. All Wood-Mizer blades are quality checked for performance throughout more than 100 tests and inspections from the selection of raw materials to the final grind.

"On our farm, we cut oak with these blades. We've never had a problem with DoubleHARD," says Copford Farm owner Alex Gingell from England.

"I used to try different blades, but finally, I chose DoubleHARD due to its longer life. They provide the best cost per volume of sawn product. The use [of DoubleHARD blades] has paid off," says Oleksandr Gaydarzhi, a sawmill owner from Ukraine.
