Diager 420D08L0120 Centering Guide Diamond Core Bit Accessories Inverter Black outer lens darker shadingHIGHLIGHTS: The Diager 420D08L0120 Centering Guide is a precision accessory designed to provide accurate alignment and easy starting when using compatible Diager M16 Diamond Core Bits. Installed at the center of the core bit before drilling, it stabilizes the bit during initial contact to prevent wandering and ensures a clean, accurate hole. Once the groove has been established, the guide is simply removed, allowing normal core drilling to continue.
