MK Diamond 163930Y MK-304RCK 12 by .125 by 7/8 inch is a Tiger Tooth premium demolition blade. This blade has been engineered for use by fire fighters, police rescue teams, search and rescue teams, SWAT and USAR and specifically designed to cut rapidly through a wide variety of materials. The applications include utilization as an emergency rescue blade and tactical entry tool as well as demolition. Provides a user with swift and efficient cutting of a diverse range of materials, such as aluminum, concrete, copper pipe, corrugated roofing, dry wall, masonry, plastic, polyethylene pipes, PVC, rebar, roof tile, stainless steel, steel, stucco, tile backer board and wood. This wide range of materials means that this blade cuts items such as acrylic, chain link, hardened stainless shackles, Lexan, metal hinges, Nader bolts, padlocks, steel doors and window bars. Using a new vacuum-brazed system, the Tiger Tooth premium demolition blade has diamond particles fused directly to its steel core. This creates an incredibly strong heat-resistant bond, the strongest bond available when cutting without water cooling. The blade can be used on hand-held grinders, circular saws, chop saws and gas cutoff saws.
