[0011] Compared with existing technologies, the advantages of this utility model are: it is suitable for drilling hexagonal nuts and bolts. The first mounting plate is fixed in the vise position through an internal and external interlocking locking and clamping method. The detachable positioning block inside the tooling is dovetail-shaped. It has pre-drilled wire cutting holes of the same size and Q-shaped, penetrating the entire block. These wire cutting holes are designed for accurate and efficient drilling of hexagonal products under a bench drill, and are strictly based on product dimensional tolerances. The positioning blocks are available in different models depending on the size of the hexagonal nuts and bolts to be processed. The first and second mounting plates are connected to the positioning blocks via U-grooves and fastening screws. Loosening the fastening screws adjusts the position of the positioning blocks. Rotating the locking screws loosens the fixing of the positioning blocks, facilitating the adjustment and replacement of positioning blocks of different sizes. The screw or nut to be cut is placed between the positioning blocks on both sides. Rotating the adjusting screws brings the second mounting plate closer to the first mounting plate, securing the screw or nut with the two positioning blocks. The cutting wire passes through the wire cutting hole to cut the screw or nut that needs to be processed. The cutting debris falls naturally into the discharge groove for easy cleaning. After cutting, rotating the adjusting bolt moves the second mounting plate away from the first mounting plate, allowing the processed screw or nut to be removed. To process screws or nuts of different sizes, simply replace the corresponding positioning block. Attached Figure Description
