Polycrystalline diamond tipped teeth deliver up to 75X the life of a traditional carbide tipped blade. Anti-friction coating keeps the blade cool while cutting and resists corrosion and gumming. Laser cutting technology creates the blade from 100\% sheet steel to ensure a stable blade that increases cutting accuracy. Laser cut vibration slots minimize wobble and warping during use. Thin kerf design delivers faster cuts as well as more cuts per charge when using a cordless tool. Optimized for both cordless and corded tools. Great for use with fiber cement products such as siding, backing, trim boards and moldings.
