EBI Spiral Stage Drill, Non-Coated, 9 Stages, Hexagonal Shaft, 4-12, LBH412SPN, 1 Piece

Catalog number: LBH412SPN Features: ●The spiral groove makes the rake angle sharper than the straight groove, and the sharpness is greatly improved. ●Since it uses cobalt high-speed steel, it has excellent wear resistance and heat resistance, and the sharpness lasts for a long time. ●It can be used for various processing such as drilling, pilot hole enlargement, hole correction and chamfering with one tool. ●It can be used for various applications and materials such as thin steel plates, pilot holes for wood screws, and curved surfaces of pipes. ●The tip bites well, so no center punch is required. Applications: ●Workpiece: Iron plate, wood, plastic, etc. (Do not use on heat-treated metal plates.) ●Since it uses cobalt high-speed steel, it has excellent wear resistance and heat resistance, and the sharpness lasts for a long time. ●It can be used for various processing such as drilling, pilot hole enlargement, hole correction and chamfering with one tool. ●It can be used for various applications and materials such as thin steel plates, pilot holes for wood screws, and curved surfaces of pipes. ●The tip bites well, so no center punch is required.
