Laser-cut from high quality Japanese steel, Hitachi's 7-1/4" 24T framing/ripping VPR blade (115429) - with tungsten carbide tips - delivers maximum durability and longevity, and precise cutting. The tungsten carbide tips are carefully welded into each tooth to control the exactness of the saw blades. An automated grinding process provides accurate tip geometry, increasing the life and performance of the blade's ATB C3 carbide teeth. This 24-inch Hitachi framing blade features tri-metal shock resistant brazing on the tips to withstand extreme impacts, for additional durability, and large micrograin carbide teeth for prolonged blade life. The 115429 VPR ripping blade includes laser-cut expansion slots (filled with silicon) to reduce noise and vibration. An electrophoresis coating protects against rust. This Hitachi circular saw blade is ideal for rough framing lumber, plywood, softwood, OSB and hardboard siding.
