[Features] ● A blade design compatible with ALC materials (with piano wire and reinforcing bars) allows for comfortable work in rotation mode. ●The thermal spraying dragon groove on the outer periphery of the core is highly effective in discharging chips, enabling speedy drilling of wet ALC materials. ● The newly developed Radius One Shank System makes it easy to change to other size core bodies. ●Two straight type and SDS type shanks are included, so it can be attached to both chuck type and SDS small and lightweight HAMMER CASTER drills. ●The "Kuzutori Pon! Center Drill" has a non-screw lock mechanism that allows you to easily remove cutting chips without disassembling the core drill body. ●Aluminum die-casting is used for the bottom of the core. (55φ or more) Workability is improved by reducing the weight of the conventional 257.
[Use] ●Work material: ALC material (with reinforcing bars), gypsum board.
