[Features] ● With a spiral groove, the rake angle is sharper than that of a straight groove, greatly improving sharpness. ●Because it uses cobalt high-speed steel, it has excellent wear resistance and heat resistance, and sharpness lasts for a long time. A single tool can be used for a wide range of processing such as drilling holes, enlarging pilot holes, correcting holes, and chamfering. Suitable for various applications and materials such as thin steel plates, prepared holes for wood screws, curved surfaces of pipes, etc. ●The tip bites well and does not require a center punch.
[Applications] ●Cover materials: iron plates, wood, plastics, etc. (Do not use on heat-treated metal plates.) ●Ideal for drilling, enlarging pilot holes, correcting and chamfering. ●Maximum drilling plate thickness (mm): steel plate 2.0, stainless steel 1.2, wood/plastic: 2.0
