HEAVY-DUTY VACUUM BRAZED DIAMONDS - Diamonds are permanently bonded to the heat-treated hi-speed steel core by our advanced vacuum brazing process to create the strongest bond possible in even the most demanding conditions and is extremely resistant to heat. Use for cutting and grinding metal such as rebar, copper, galvanized steel, conduit, angle iron, ductile iron, stainless steel, and more. Will also cut through plastic, PVC, drywall, concrete, granite, and more.
LASTS 100X LONGER - A single Diamond Extreme blade outlasts and out performs up to 100 abrasive cut-off wheels. Save time by using one blade without having to constantly put on a new disc after a few cuts. Diamond Extreme blades use a heavy-duty vacuum brazed diamond bonded segment and will not wear out as fast as other diamond discs.
CONSTANT CUTTING DEPTH & SAFER - Abrasive discs wear down and will shrink which can be dangerous. Diamond Extreme maintains a constant cutting depth, giving you the maximum cutting depth throughout the life of the blade. The steel core makes the blade much safer to use and produces far fewer sparks and dust. Commonly used by fire departments for fire/rescue situations across the country.
SPECIFICATIONS - 16" diameter X .140 thick with a 1" arbor. Included preinstalled 20MM bushing for adapting to just about any hand held power saw or cut off saw. The maximum safe operating speed is 4,725 RPM.
LIFETIME WARRANTY & FREE RETURN SHIPPING - All Delta Diamond Products, Inc Diamond Blades, Coring Bits, Hole Saws and Grinding Wheels include a lifetime warranty against warping, cracking, and material defects. If any diamond tool (being used under its intended use with at least 50% wear left) fails to cut or work properly, or if the bond between the diamond segment and the steel core becomes separated at any time, the diamond tool will be replaced free of charge.
