Xlertor blades are designed to stay cool and dissipate heat under the most demanding conditions. With a “Vented Core” and specially designed gullets which create an “Airfoil” around the blade to keep the blade cool, which results in better cuts, increased performance & longer life. With extra large laser-welded segments in either 10mm or 15mm you'll get longer life and increased durability. They cut up to 3x faster than conventional blades and will increase your tool life dramatically.
